William Henry Murdoch

William Henry Murdoch
Murdoch Mysteries character
First appearance	Except The Dying
Created by	Maureen Jennings
Portrayed by	Peter Outerbridge (TV movies) Yannick Bisson (TV series)
In-universe information
Gender	Male
Title	Detective, Deputy Inspector
Occupation	Police officer

Relatives	Harry Murdoch (father) Mary Murdoch (mother) Susannah Murdoch (younger sister) Sergeant Jasper Linney (older halfbrother)

Yannick Bisson, the actor who plays Murdoch

Detective Murdoch, who is portrayed by Peter Outerbridge in the TV movies and by Yannick Bisson in the series, is an intelligent, observant detective who uses unusual (for the time) techniques such as blood testing and fingerprinting. It is revealed he comes from Nova Scotia, is a devout Roman Catholic who was educated by the Jesuits and is fluent in French. In one episode, it is revealed that he believes that his father beat his mother and may have indirectly caused her death, although this was proven incorrect. Following that incident, he was taken to live in an orphanage for a time.

Murdoch is also a polymath: Although very logical, sceptical, observant, scientific and clear-headed with a photographic memory (possibly Hyperthymesia) and working memory, these become an issue when he needs to connect with people on an emotional level, something he finds difficult. Often his unusual techniques and unbiased opinions of people lead him to clash with Brackenreid (even though they work together well). In season 9, episode 11, Murdoch takes up golf and does quite well till a machine he invents ruins his "swing". Julia plays well and Murdoch is told all he has to do is empty his mind to again play well. This is something he cannot do and he ends up angrily throwing his clubs in the lake, one by one.

Murdoch often consults on cases with Dr. Julia Ogden, with whom he is infatuated, although he did not attempt a relationship with her until the first half of season 2. As the season progressed, an argument over beliefs and past decisions made by Ogden split up the couple for a time, during which time Murdoch pursued a relationship with Enid Jones. However, he and Ogden rekindled their relationship during the season 2 finale on the advice of his half-brother (see below), and it becomes "public" (despite everyone already knowing about it) in the first episode of season 3. Ogden and Murdoch become engaged in the finale of season 7 and are married in episode 4 of season 8.

In the season 2 finale, it is revealed his father had another son, Jasper Linney (of whom Murdoch knew nothing) out of wedlock, before marrying Murdoch's mother. Jasper is a sergeant in the North-West Mounted Police and his mannerisms, interests and investigative techniques are similar to those of Murdoch's own (mentioned above), and the two prove successful in working together to solve a gold mining scam case. In the season 4 episode Voices, it is revealed that Murdoch has a younger sister, Susannah, who is a nun living in Toronto briefly before returning to her convent in Montreal when it is revealed she is terminally ill. Their conversations reveal that they had an aunt, whose home he left at seventeen, to work at a logging camp. This episode also mentions that Murdoch's father was still alive two years prior and lives in Western Canada.

In season 1, episode 4, it is revealed that Murdoch once had a fiancée, Liza Milner; she died a year prior of consumption.

In season 9, episode 10, "Raised on Robbery", he and Julia have adopted a son, Roland, the orphaned son of the bank-robber couple; however, in episode 14, "Wild Child", when they find out that the couple were not Roland's biological parents, Murdoch and Julia make the heart-breaking decision to give up Roland and reunite him with his real father (the mother having died in childbirth.) Murdoch later learns he has a son, Harry, from his relationship with Anna Fulford. In season 15, William and Julia welcome a daughter of their own, named Susannah after William's late sister.

In a crossover with fellow CBC show Republic of Doyle, called "If the Shoe Fits", a modern-day version of Murdoch appears in the form of "Bill Murdoch", who is the great-great-great-grandson of William.

Thomas Charles Brackenreid

Thomas Charles Brackenreid
Murdoch Mysteries character
First appearance	Except The Dying
Created by	Maureen Jennings
Portrayed by	Colm Meaney (TV movies) Thomas Craig (TV series)
In-universe information
Gender	Male
Title	Inspector, Chief Constable
Occupation	Police officer
Spouse	Margaret Brackenreid

Inspector (later Chief Constable) Thomas Brackenreid (portrayed by Colm Meaney in the TV movies and in the TV series by Thomas Craig) is a middle-aged married man, fond of the theatre and a good drink. He is the head of the stationhouse and does most of the interrogating, often forming opinions of a suspect because of personal impressions or their social standing. Quick to anger and tenacious, with a sarcastic sense of humour, he is better at traditional "coppering" and is very proud of his job and what he feels is his duty to protect the city.

While he often disagrees with Murdoch's methods, he uses them when he feels they have merit. He has little time for Crabtree until the second half of the fifth season where he takes him directly under his wing and actually seems to care deeply for him. He is shown to care for Murdoch and knows his mannerisms well enough to know when he is pining and advises him to do something about it.

Throughout the second season Brackenreid is forced to hide his drinking habits from his wife, who has joined the temperance movement.

In the third season, it is revealed that Brackenreid is a Freemason, as is Constable Crabtree (who happens to be of higher rank, as he can watch his language, etc., better than Brackenreid can).

At the end of the seventh season Brackenreid suffered a severe beating from a gang of thugs that was controlling the harbour. The first two episodes of season eight detailed that, although he had physically recovered, he was initially adamant about leaving his job, fearing that his family might be endangered. After being convinced by his wife that being a policeman was his life, he began a lone and almost maniacal search for the person responsible for the attack and other crimes, proving willing to eschew the "rules" to achieve his objective. Although he came close to killing the culprit, in the end he abided by the law he had served for years and returned to his job as Inspector.

At the end of Season 17 Brackenreid is appointed as the new Chief Constable.

Brackenreid paints as a hobby. Although his colleagues and family don't always appreciate his work. His style greatly resembles Canadian painter Tom Thomson.

Brackenreid is from Yorkshire, England and has two young sons with his wife Margaret, John and Bobby. John, the elder son, would become a Constable under his father at station house four in season 11. Before he became a policeman, Brackenreid served in the British Army and fought in Afghanistan. He is a supporter of Sheffield Wednesday Football Club.

Dr. Julia Ogden

Julia Ogden
Murdoch Mysteries character
First appearance	Except The Dying
Created by	Maureen Jennings
Portrayed by	Keeley Hawes (TV movies) Hélène Joy (TV series)
In-universe information
Gender	Female
Title	Doctor
Occupation	Pathologist, general practitioner, psychiatrist
Relatives	Dr. Lionel Ogden (father) Ruby Ogden (sister)

Doctor Ogden, who is portrayed by Keeley Hawes in the TV movies and by Hélène Joy in the TV series, attended Bishop's University and is a skilled pathologist and medical examiner. (In 1894, a woman did graduate from Bishop's University and become a skilled pathologist: Dr. Maude Abbott.) However, it is later (episode 11.05) said that she studied under Dr. William Osler at McGill University (McGill University did not admit women to the Faculty of Medicine until 1918). The first of two sisters, Dr. Ogden was a tomboy in her youth and has a criminal record for skinny dipping with some university colleagues (episode 2.04). Her mother is dead, and she has a strained relationship with her father. She enjoys tennis, reading, cycling and attending the theatre. Through her family connections, she is quite well known in Toronto's upper class society (episode 1.08). Dr. Ogden is often consulted on cases by Murdoch and is able to provide valuable insights into many cases. They, along with Constable Crabtree, enjoy the intellectual puzzles that many murder mysteries present.

In the first season, she and Murdoch begin a tentative romantic relationship. In episode 2.06, Dr. Ogden tells Murdoch that she became pregnant when in university and terminated it. (Abortion in Canada was illegal during 1869-1969.) As Murdoch struggles to come to terms with this knowledge, Ogden decides to end their relationship, believing that, due to his Catholicism, he will never accept what she did or that she still feels it was the right decision. Their relationship is awkward until the end of the final episode of season 2 when Dr. Ogden agrees to discuss restarting the relationship.

At the end of Season 3, she leaves the Constabulary to go work in a children's hospital in Buffalo, New York. It is revealed that she cannot give birth to a child due to the previous abortion, and for this reason she decides to terminate her relationship with Murdoch. Murdoch tries to stop her leaving and intends to propose to her despite knowing about her condition, but arrives late at the train station. (In a daydream that he has about proposing, he intends to tell her that he does want a family, but that they can adopt. However, he never has this conversation with her in real life, and she leaves Toronto not knowing about his intentions for either marriage or family.) Dr. Ogden does not return to work in the morgue at the start of season 4, but Murdoch writes to her to help solve a case. She does not appear in episode 2, but does appear in episode 3 (Buffalo Shuffle), where Yannick Bisson makes his directing debut. Murdoch brings the engagement ring with the intention of proposing, but Dr. Ogden reveals that she is already engaged to a doctor working at the children's hospital in Buffalo. She returns to her old position in Toronto several episodes later. Her fiancé takes a position at a Toronto hospital to be with her. In the last episode Julia marries Dr. Darcy Garland, despite her affection for Murdoch.

At the beginning of the season 5 (Back and to the Left), however, she terminates her employment in the City Morgue and starts her own private practice in Toronto, leaving the work to her protégée, Dr. Emily Grace. Julia states that with her feelings towards Murdoch maintaining their professional relationship would jeopardize her marriage. Later on in the series she actively participates in a birth-control campaign, which complicates her husband's social position and even leads to her arrest. At the end of the season, she and Darcy separate. In season 6, Julia is working as a psychiatrist, often assisting Murdoch with his cases. She is actively trying to divorce Darcy and is framed for his murder at the end of the season, though Murdoch uncovers the real killer and clears her name barely in time to prevent her execution by hanging. The trauma of her experience and guilt feelings cause her to withdraw from Murdoch at the season 6 finale; but, in season 7, their relationship seems to be back on track, and they become engaged in the finale. They are married in the fourth episode of season 8.

In season 9, episode 10, Raised on Robbery, she and William briefly adopted a son, Roland, the orphaned son of the bank-robber couple. When Julia discovers the child's actual father is still alive, they reluctantly return Roland to his father. However, the experience with Roland encourages William and Julia to seriously consider adopting a child of their own. In season 11, episode 4 (The Canadian Patient), Julia meets a woman conducting research into fertility treatments, and offers herself as a potential test subject. In episode 11 ("Biffers and Blockers"), Julia reveals to William that the treatments have worked and she is pregnant. Julia suffers a miscarriage in the fourth month of her pregnancy (season 11, episode 17, "Shadows are Falling"). She later becomes pregnant again and gives birth to a daughter, Susannah, named after Murdoch's late sister. Dr. Ogden's pregnancy in the series coincided with Hélène Joy's own pregnancy and was written into the show.

Julia's father, Dr. Lionel Ogden, died in the season 7 finale. She has a younger sister, Ruby Ogden, who is a minor character in the series and a journalist, who often travels the world.

Constable George Crabtree

George Crabtree
Murdoch Mysteries character
First appearance	Except The Dying
Created by	Maureen Jennings
Portrayed by	Matthew MacFadzean (TV movies) Jonny Harris (TV series)
In-universe information
Gender	Male
Title	Constable 1st Class, Deputy Detective
Occupation	Police officer

Jonny Harris

Murdoch's assistant, Constable Crabtree, is portrayed by Matthew MacFadzean in the TV movies and by Jonny Harris in the TV series. Although inexperienced at first and often comically naive, Crabtree frequently provides useful insights into cases and does much of the forensic legwork collecting evidence.

In early seasons, Crabtree is eager, but has yet to master Murdoch's more advanced scientific skills. He is very loyal to Murdoch, willing to threaten one of Ogden's suitors when Murdoch asked him to investigate him; he also knows Murdoch's mannerisms rather well. While Brackenreid initially regards him as an idiot, over time, Crabtree and some of the other constables prove adept at learning Murdoch's methods (e.g. photography) and eventually gains Brackenreid's respect and the possibility of promotion to detective.

Crabtree dates a number of women over the years, but the relationships tend to be doomed by circumstances. At the end of season 8 and the start of season 9, he proposes to Edna Brooks, but she learns she is not a widow—and then her husband is murdered. Fearing that Edna is guilty, Crabtree protects her by allowing himself to be prosecuted and convicted, via Nolo Contendere. Consequently, he is not promoted, but demoted to Constable Third Class, after Murdoch finds the real killer.

Crabtree often has ideas for commercial uses for Murdoch's inventions. Murdoch usually dismisses them as absurd, but they often prefigure real successful products. Crabtree also aspires to be a mystery novelist. His first novel, The Curse of the Pharaohs, is published in season 5. (Concurrently with that season, Curse of the Lost Pharaohs also aired on Citytv.com as a mixed live action/animation web series dramatizing the plot of Crabtree's manuscript.)

Crabtree revealed in one episode ("Big Murderer on Campus") that he did not know who his biological mother was and was left on the doorstep of a church and taken in by the family there. He was later re-united with his mother at the end of the episode after taking part in a plan to uncover the murderer of a professor; he learns that she was forced to leave him on the church's doorstop after her husband died and she couldn't provide for their son. Crabtree also frequently refers to his many "Aunts", each of whom seems to be named after a variety of flower. In the season 7 episode "Republic of Murdoch", it is revealed that these Aunts are, or at one time have been, prostitutes who live in a large house rented to them by the Reverend who became Crabtree's guardian after he was abandoned. Crabtree, while having-been born in Toronto, was raised in Newfoundland.

In season 3, it is revealed that Crabtree is a Freemason, along with Brackenreid, and turns out to be of higher rank than the inspector, as Brackenreid cannot refrain from his use of bad language, etc.

Crabtree also has a difficult time with a flighty socialite named Roger Newsome, whom he has numerous dealings with, to his irritation. His deepest cause for this enmity was when Newsome was assisting Crabtree on a case and at one point Crabtree was being attacked with deadly intent by a criminal. Rather than do anything to assist his police companion in mortal peril, Newsome abandoned him in blatant cowardice, and Crabtree required assistance from others. Newsome never adequately apologized for his failure and would meet the unforgiving Crabtree on numerous other occasions. However, when Newsome was murdered by a sniper to silence his testimony for a murder trial in the episode, "Weekend at Murdoch's", Crabtree was able to spare a bit of politeness for him under the circumstances. In the show's 16th season, he marries Roger Newsome's cousin Effie (Clare McConnell).

Dr. Emily Grace

Emily Grace
Murdoch Mysteries character
First appearance	Murdoch of the Klondike
Last appearance	Double Life
Portrayed by	Georgina Reilly (TV series)
In-universe information
Gender	Female
Title	Doctor
Occupation	Coroner

Georgina Reilly

Portrayed by Georgina Reilly, Emily Grace is the new coroner who joins the morgue in season 5 as Dr. Ogden leaves to set up her private practice. Initially described as Dr. Ogden's protégée, Dr. Grace is a trained medical doctor but admits she prefers pathology because she has little patience to maintain a good bedside manner. She is interested in spiritualism, believing that it is compatible with scientific study. Though eager and impatient, she quickly learns the rules of the station house and proves to be a highly competent coroner to Murdoch in his investigations.

Emily later becomes a love interest for Constable Crabtree; they become good friends and she often enjoys his company and entertains his far-fetched theories with some enthusiasm. A tentative romance develops between them in season 6, but George breaks off their relationship after she kisses Leslie Garland, the brother of Julia Ogden's first husband Dr. Darcy Garland. (She kisses Leslie to prevent him from ruining her undercover disguise as Mademoiselle Desiree Deneuve). Leslie asks her out to dinner and Emily initially refuses, but as she is no longer dating George, she consents to having dinner with Leslie, unaware that George was on his way to Emily's office with flowers and seeking to reconcile with Emily.

After Emily finds out that Leslie was behind the threatening letters to Dr. Ogden, Emily ends things with Leslie. George is still initially quite distant with Emily, though gradually they become friends again. Emily joins the Women's Suffrage movement in season 8, becoming a strong advocate and encouraging Dr. Ogden to support them. Through the suffrage movement, Emily becomes acquainted with Lillian Moss and they eventually enter a romance. In season 8, Lillian Moss proposes to her to move to London, England, and fight there for the women's suffrage. Though Lillian is murdered by the husband of her ex-lover, Emily still chooses to follow through with moving to London and finally leaves Toronto for London alone at the end of the episode 3, season 9 "Double Life".

Supporting characters

Constable Henry Higgins

Portrayed by Lachlan Murdoch. Constable Henry Higgins is a police constable at Toronto's station house four. He frequently assists George Crabtree in investigations.

Higgins is best known for doing his own thing when it comes to any sort of case or off duty business, ranging from locating a new kind of ice cream with George (Season 9 Episode 15, House of Industry) or watching boxing fights with Jackson (Season 8 Episode 3, Glory Days). It appears that he and George are best friends, and that he is somewhat of an assistant to him. Higgins has appeared in almost all the episodes. Higgins was amongst the sceptical constables to whom Murdoch presented his Pneumograph (Season 1 Episode 8, Still Waters"). Henry was also one of the three who contributed to the purchase of the motor car between himself, George and Jackson in Murdoch Takes Manhattan.

Henry is prone to making frequent mistakes in episodes, but usually has a redeeming moment towards the end. Detective Murdoch has taught Henry how to correctly make shoe impressions in the mud in Child's Play after Henry messes up three footprints beforehand, having no clue how to do them exactly. When Prince Alfred visited Toronto and Constable George Crabtree was assigned to his security, Higgins assisted Detective William Murdoch with an investigation into the murder of Maggie Gilpatrick. Murdoch taught Higgins about fingermarks and how to trace a person's next of kin. When it was determined there was a plot to kidnap Prince Alfred, Higgins was selected to impersonate the prince to help safeguard His Highness (Season 1, Episode 12, The Prince and the Rebel). However, Higgins also tends to let words slip out of his mouth before thinking about them, but means no harm. Such an example of this is during Unlucky in Love (Season 9 Episode 12) when Higgins accidentally insults Baby Roland Connor when Detective Murdoch is worried about Roland not walking yet and suggest that 'Maybe he's just slow.' which annoys Murdoch. Higgins later apologizes sincerely for this though, never meaning to speak ill of Murdoch's son. Nevertheless, Henry has proven himself to be good with young children, during this episode as well as "Raised on Robbery" (Season 9 Episode 9).

Growing up, Higgins family owned a piano shop. He did not enjoy playing, but he loved all of the parts. (Season 7 Episode 17, "Blast of Silence") It's also known that Henry's mother is from the Gaspé in Quebec, and he knows how to speak a bit of French as shown in "Convalescence and Monsieur Murdoch". Higgins has a homosexual cousin and so was aware of the secret gay club where homosexual men gathered in Toronto (Season 1 Episode 5, "'Til Death Do Us Part").

In "War on Terror" (Season 5 Episode 4), Henry is caught in an explosion along with George and is rendered unconscious, resulting in George attempting to find the culprit behind the bombing of Milne's store. The bomber is caught, and Higgins returns to the station house having been hospitalized for the majority of the episode. In the beginning of Season 10, (Season 10 Episode 1, Great Balls of Fire, Part 1) Higgins picks up smoking cigars, but whether this was just to impress the Inspector or not is unknown, as we're never shown him smoking again after.

At the end of the Season 10 finale (Season 10 Episode 18, Hell to Pay), along with Constable George Crabtree and Constable Slugger Jackson, Henry is caught in an ambush; all are shot and possibly murdered.

In Season 11, Higgins begins courting Ruth Newsome (of the Mimico Newsomes), sister of Roger Newsome, who was involved in several of Murdoch's investigations. In Episode 11 ("Biffers and Blockers"), Higgins has taken up cricket and also engaged a butler, at Ruth's suggestion, part of his transformation to join the upper class. In Episode 12 ("Mary Wept"), Henry attempts to propose to Ruth but is interrupted when a body falls from a bell tower and lands just behind him, traumatizing Ruth. Ruth later proposes to Henry herself and is accepted. While Henry quits the constabulary believing that he has married into wealth, the apparent loss of the Newsome fortune humbles him into asking for his job back and begins moonlighting as a motorcar cab driver for additional money to support his new family. He later becomes a father to a daughter, Jordan Higgins-Newsome. Despite retaining his laidback demeanor, Henry becomes more reliable as a constable, particular when George is absent.

Rebecca James

Portrayed by Mouna Traoré, Rebecca is a young woman of humble origins who has recently arrived in Toronto, living at the Junction, and working as an overnight cleaner for the city morgue. Dr. Ogden meets Rebecca on her first day back as the Chief Coroner, where Rebecca exhibits a genuine interest in anatomy that Dr. Ogden appreciates. Because she is African Canadian, a number of people are unhappy with the attention that Dr. Ogden gives her. When Rebecca is dismissed from her position for removing evidence from the morgue for an experiment that provided evidence, Dr. Ogden hires her back as Morgue Assistant. It is revealed that Rebecca attended a year at the New York Medical College for Women. When her patron died, his son was less inclined to support her schooling so she had to leave. She eventually resumes her medical studies at the Ontario Medical College for Women while working at the morgue, and her application to work at the City Morgue is officially granted at the end of Summer of '03. She later completes her studies to become a family doctor and departs to open a medical practice in Chatham, where she eventually marries her sweetheart, Nate Desmond.

Margaret Brackenreid

Margaret, portrayed by Arwen Humphreys, is married to Inspector Thomas Brackenreid and together they have two young boys. Margaret is a very passionate woman, who is always very determined in everything she does. Thomas Brackenreid had just come out of the army when Margaret's father asked him to join the family's plumbing business. Margaret thought he'd have been a good plumber, but his heart was set on the police force. Married to a policeman, she knew what she was getting into, no point in complaining about the long hours – and the worry. But still... after they had two sons, Margaret does worry about her husband's safety due to his career as a police officer. Margaret does not like the opera but instead enjoys classical music on their gramophone. She is a good cook, bakes her own bread, and is noted for her excellent plum pudding at Christmas by Murdoch. She is involved in the temperance movement for a period, and once becomes suspicious of her husband's relationship with an opera singer, but is typically portrayed as a loyal and loving partner. Brackenreid has stated he met Margaret when he was a beat cop and he arrested her for causing a disturbance. She and Thomas have two children, John and Bobby. John, the elder son, would go on to become a Constable under his father at Station House Four much to his mother's chagrin; after a near life-threatening accident, John leaves police work to become an actor instead, to Margaret's relief. Margaret is greatly distressed when her younger son Bobby is involved in the death of a boarding school classmate and disappears to evade justice, finding relief only after Bobby returns to face charges, even though he is ultimately convicted and incarcerated. In season 9, episode 13, Unlucky in Love, Margaret Brackenreid has started a Wedding planner business. She is later hired as a nursing assistant for Dr. Ogden at the Toronto women's medical clinic.

Detective Llewellyn Watts

Portrayed by Daniel Maslany, Llewellyn Watts (known as Detective Watts until his first name is revealed in "Hades Hath no Fury" (season 10, episode 15) is a detective, originally from station house 1 who in "Concocting a Killer" (season 10, episode 4) is brought to station house 4 to re-examine a case where new evidence has arisen that may mean a man sent to prison by Murdoch could be exonerated. In "A Murdog Mystery" (season 10, episode 11), when Inspector Brackenreid leaves station house 4 to accompany James Pendrick to Panama, Watts is brought back as the station detective while Murdoch serves as the acting inspector. Detective Watts is assisted by Constable Slugger Jackson in some ongoing missing persons cases, which eventually leads Watts to his long-missing older sister ("Hades Hath no Fury" (season 10, episode 15)), who abandoned him when he was a child (their parents were dead and she just saw him as a burden). In "Up From Ashes" (season 11, episode 1) and after Inspector Brackenreid's return, Watts remains working with station house 4. In "Murdoch Schmurdoch" (season 11, episode 15), while investigating the murder of a Jewish man, Watts recognises a Yiddish lullaby as the same one his late mother used to sing to him. Llewellyn is told that if his mother sang that, his family must be Jewish. Llewellyn thinks it unlikely as "Watts is not a Jewish name." He's told that names are often changed when families immigrate, and if his mother was Jewish, so is he. After researching, Llewellyn discovers his family's original name was Wattenberg, but his parents changed it when they immigrated to Canada).

Like Murdoch, Watts is extremely well-read and philosophical, approaching his cases with objective analytical logic in the vein of Sherlock Holmes. However, Watts prefers performing his investigations outdoors and on the streets. He can be difficult to work with because he tends to speak with little regards to social graces and voices his thought processes aloud and unfiltered. Watts' eccentric body language and speech patterns are reminiscent of famous Canadian pianist and personality Glenn Gould.

In season 13, Detective Watts begins a relationship with Jack Walker, a local butcher that Watts meets during a case. Their relationship becomes romantic, but they are forced to keep the true nature of their relationship discreet, owing to laws against homosexuality and to avoid damaging each other's public reputations. Jack later marries a woman named Clara, who is pregnant with their son Samuel, and breaks up with Watts. Watts briefly entertains a relationship with poet Milo Strange, but returns to Jack when Jack tries to run away with Samuel and Watts to New York, and Watts has quit the Toronto Constabulary out of disgust over Brackenreid's apparent decision to manipulate evidence to ensure the arrest of a Black man who was guilty for other crimes that could not be proven. Although Inspector Brackenreid had turned a blind eye to Watt's relationships, Brackenreid's temporary successor Inspector Edwards arrests Watts on charges of indecency related to homosexual activities. On principle, he refuses to leave his prison cell after all the other men are released and begins a hunger strike, until Violet Hart spikes his water with amines and encourages him to use his voice in a setting where he will be heard. He rejoins the constabulary at the request of George when the latter becomes acting inspector of station house 4 while Brackenreid is away in England to care for a sick relative and Murdoch has been abducted.

Introduced as an entrepreneur selling nutrition pills, Dr. Ogden offers Violet the opportunity to attend university and work with as her assistant at the morgue, making her ambitions to Dr. Ogden clear that she does not intend to remain Dr. Ogden's assistant forever. While impressed with her aptitude, Dr. Ogden becomes concerned with Violet's apparent lack of compassion. However, Inspector Brackenreid looks favourably upon Violet's competence and recommends her to officially take over the morgue as its chief coroner when Dr. Ogden departs to become a surgeon, becoming the first black woman to hold the position. Murdoch finds it increasingly difficult to trust Violet, despite her professionalism, suspecting that Violet may be involved in unlawful activities.

Miss Hart's ambitions and shady past eventually nearly undo her success. To secure her position as coroner, she aligns with upcoming politicians until she learns the extent of their corruption extends to murder. She is given a second chance by Murdoch and Brackenreid, and is allowed to remain at the morgue.

Violet later marries millionaire socialite Arthur Carmichael, but she grows frustrated that Arthur married her only to shock Toronto's elite for his own amusement. She coerces him into submission and takes control of his finances, investing her new wealth into Toronto's Black community through the local Starbright Club run by Cassiopeia Bright. The unexpected arrival of her criminal father, Isaiah Buchanan, results in Arthur's murder and the loss of Violet's fortune.

In season 11, Louise is arrested for impersonating the Mercy Killer by fabricating letters from the murderer published the Toronto Gazette. Later, she is hired by another paper, The Toronto Telegraph, and receives a visit from the editor while in jail. His offer is quite generous; he offers a more prominent title and wages significantly more substantial than she was receiving at the Gazette. George briefly dates Louise, but learns how she thinks poorly of his friends and finds her blunt personality makes them incompatible. However, he does value her feedback on his literary career and they maintain a tentative friendship.

Robert Parker

Portrayed by Marc Senior, American Robert Parker is a private investigator who served in the U.S. Army and was a Pinkerton agent who was once part of the squad that tracked Butch Cassidy to Colorado. He arrives in Toronto to find the Pinkerton agent who ordered the death of his brother Daniel, also a Pinkerton agent, who was considered expendable as a black man. He eventually forms an informal partnership working at Station House Four as a special constable and demonstrates a strong sense of justice. His undoing comes when he attempts to arrest con artist John Lincoln, who has arrived in Toronto to blackmail Violet Hart, without substantial proof that Lincoln was responsible for a recent murder. The action draws attention to his unrecognized status as a special constable to the chief constable, who orders Brackenreid to fire Parker, leaving him feeling betrayed and believing his colleagues at Station House Four do not support him because he is black. Although Miss Hart warns him to leave the city to protect himself from repercussions, he refuses and continues to investigate Lincoln.

Unsure of what to do, the police leave Dr. Roberts in his frozen state.

Minor recurring police officers

Chief Constable Percival Giles

Nigel Bennett

Portrayed by Nigel Bennett. The Chief of police, he succeeded Chief Constable Stockton. He believed that Murdoch set a prisoner free in season 4 episode 13, "Murdoch in Wonderland"; in the season 5 episode 1, "Murdoch of the Klondike", Brackenreid covered for Murdoch with the story of a faulty lock. Giles did not believe this story but because he did not have any evidence, he could not arrest Murdoch. However, because of that, in a number of episodes in season 5, Giles seemed to have something personally against Murdoch and was always against anything that Murdoch said in any episode that had both Giles and Murdoch. The storyline with Giles personally hating Murdoch was dropped from the program, and because of that in season 6 episode 6, "Murdoch and the Cloud of Doom", when somebody threatened Toronto with a deadly toxic gas, Giles personally asked Murdoch to find the person. In season 6 episode 12, "Crime & Punishment" he arrested Dr. Ogden for the murder of her husband Dr. Darcy Garland and suspended both Murdoch and Brackenreid, but when they secretly continued their investigation, he reinstated them. In season 8, episode 7, Giles admits to being homosexual, regarding which another constable years prior had tried to blackmail him.

He is still working in the pub in episode 18, "Free Falling".

Recurring antagonists

James Gillies

James Gillies, portrayed by Michael Seater, is Detective William Murdoch's nemesis. He is a cold, calculating, murderous criminal mastermind who hides behind a facade of cordiality. Gillies views his nefarious schemes as high-stakes games in which he and Murdoch match wits and, for which, there must be a clear winner and a loser. Priding himself on always being one step ahead of the detective, he often employs people as dispensable pawns to aid in his machinations, not hesitating to kill them when they no longer prove useful, to ensure their silence. During his first appearance, Gillies is shown to be a gifted student and teacher's assistant along with his friend and fellow teacher's assistant, Robert Perry. Murdoch eventually discovers that Gillies and Perry had murdered their physics professor, supposedly to test their knowledge of physics. Under pressure, Perry confesses to his involvement in the crime and implicates Gillies, after being tricked into believing that Gillies intended to kill him as well.

Gillies is arrested, convicted, and sentenced to death for his crimes; but he escapes from his execution and seeks revenge against Murdoch. Gillies kidnaps and buries Dr. Julia Ogden alive. Though Dr. Ogden is saved, Gillies escapes again. In his next act of revenge, Gillies frames Julia for the murder of her estranged husband, Dr. Darcy Garland. After capturing Murdoch, Gillies sets an elaborate trap to pressure Murdoch into choosing either his own life or that of the convicted Julia's. Though Murdoch chooses to save Julia, he is rescued, and Gillies is apprehended. Gillies is boarded on a train headed to Kingston where he is to be hanged for his crimes. While Gillies manages to escape from the train, Murdoch pursues him. After pinning Gillies down, Gillies distracts Murdoch with a kiss and jumps off a bridge, to escape. Despite an extensive manhunt undertaken by the Toronto Constabulary, Gillies is nowhere to be found, and it seems likely he perished from his fall.

After Gillies' fall, Julia begins receiving letters from someone claiming to be Gillies. The author of the letters threatens to kill Murdoch should Julia accept Murdoch's proposal for marriage or reveal the existence of the letters. Murdoch, Ogden, and Brackenreid begin investigating whether Gillies is alive, which results in finding what appears to be Gillies' body downriver from where he threw himself off the bridge. After Dr. Ogden and Dr. Emily Grace examine the badly decomposed body and perform a facial approximation on the skull, they and Murdoch believe the body to be Gillies'. The key piece of evidence suggesting the corpse is Gillies' is a bullet found embedded in its shoulder. Constable George Crabtree had shot Gillies in the shoulder, and the bullet was never removed. After careful examination, Murdoch ascertained the bullet to be the same that Crabtree shot Gillies with.

Years later, a murderer is caught who claims to be possessed by the spirit of James Gillies. Murdoch and Dr. Ogden interrogate the man and coax information from him that leads them to realize that Gillies is alive, having faked his death by killing someone of similar appearance, embedding the bullet George Crabtree shot him with into the corpse's shoulder, and throwing the corpse in the river he jumped into. After giving a clue to the whereabouts of Gillies, the murderer kills himself. Ogden's autopsy of the murderer reveals a small wireless radio transceiver hidden in his body as well as an even smaller wireless electroacoustic transducer embedded in his skull—both of which are soon after discovered to have been commissioned and implanted by Gillies. After following the clues to the address of a girl Gillies once kidnapped, he finds a talking doll whose message seems to suggest that Gillies has once again kidnapped Julia. Murdoch rushes to his home only to find Gillies instead holding Murdoch's young son hostage with a syringe filled with heroin. Gillies, who, as a result of his fall suffers from chronic pain and has a severely disfigured face, wants Murdoch, the man he most loves and respects, to kill him. Murdoch hesitates at first, desiring Gillies to receive punishment by the state, but then fires his gun at Gillies after Gillies threatens his son with the syringe. The gun, however, had been surreptitiously emptied of all but one bullet by Gillies sometime earlier, and doesn't fire. Gillies, given a renewed sense of purpose by his brush with death at the hands of his greatest adversary, still hovering over Murdoch's son with a syringe, and seemingly back in control, taunts Murdoch, telling him that he looks forward to the fun they will have together. However, Murdoch slides out a sleeve gun and shoots Gillies with a rubber bullet, incapacitating him. Gillies is captured and finally hanged for his crimes. Dr. Ogden performs Gillies' autopsy and removes his brain so that it may be studied, as she promised him she'd do years before on the train.

Eva Pearce

Portrayed by Daiva Johnston, Eva Pearce becomes Murdoch's nemesis, a white collar thief, kidnapper, and killer. She was deadly, manipulative, and cautious, making her a dangerous opponent of William Murdoch.

In her first appearance, Eva is introduced as a shop girl in the prestigious T. Eaton Co. department store where someone has been murdered. She flirts with Murdoch, who is unaware of her attentions until Dr. Ogden points it out to him. She is revealed to be responsible for causing murders by manipulating men that she seduces. Though Murdoch thwarts her plans to court a wealthy man, she gets away and manages to attract another suitor. She subsequently takes on the identity of Cassie Chadwick, claiming to be the illegitimate daughter of Andrew Carnegie, and manages to become the fiancée of Ian Worthington, president of the Canadian Bank. Her scheme to marry Worthington and force him to take on her debts fails when Murdoch exposes her true identity and she is arrested. Eva is later sent to an insane asylum, where she and other female "lunatics" such as Mrs. Lynd, Rose Maxwell, and Charlotte, as well as a murderess named Hannah, concoct an escape plan. Eva is the only one who manages to escape, securing her freedom by tricking a man into giving her a cab ride. Presumably she will continue to con men into getting what she wants. In her final appearance, the now-mentally-unstable Eva attempts to kill Julia and kidnaps Murdoch, with the intention of forcing herself on him to "give him the child he has always wanted" as she has become obsessed and delusional with him, having never succeeded in seducing him.

Amelia and Dorothy Ernst

Portrayed by Sarah Swire, Amelia and Dorothy Ernst are identical twin sisters. Amelia develops an obsessive interest in George Crabtree through his novels, and abducts him with the intent of coercing him into marriage. After persuading her to let him escape, her sister Dorothy appears as Effie Newsome's clerical assistant, with no apparent knowledge of Amelia's past doings. George believes Dorothy is lying or is actually Amelia, though he fails to prove either to Effie or Dr. Ogden. Dorothy later reveals that she was indeed lying to find a way to get close to Effie, in order to abduct her and hold her hostage to force George to marry Amelia. George and Effie manage to escape the ordeal, while both sisters remain at large.

Ralph Fellows

Portrayed by Colin Mochrie, Ralph Fellows is introduced as a hotel detective who begins to hold a grudge against Murdoch that grows increasingly murderous as he believes Murdoch looks down on his investigative skills.

Historical figures

Several additional historical figures have been presented in the series.

Nikola Tesla

Portrayed by Dmitry Chepovetsky. The famous inventor, Nikola Tesla, helps Murdoch solve the case in the very first episode. He really likes inventing things and improving things as he was working on transmitting wireless phone calls throughout the episode. Later in the episode he feels that his work will not make him rich, so he explores new options. He reappears in a later episode.

He re-appears in season 13, episode 11, "Staring Blindly Into the Future".

Arthur Conan Doyle

Portrayed by Geraint Wyn Davies. He first appears in Season 1, episode 4 ("Elementary, My Dear Murdoch"), visiting Toronto to deliver a lecture on spiritualism. He returns in episode 9 ("Belly Speaker"). He follows Murdoch, trying to get a grasp on detective work for a future book and personal detective skills. He refers to Murdoch and himself as "similar people", because of their fathers both being alcoholics. He reappears in season 6 to help with the matter of a man with a personality disorder that led him to believe he was Sherlock Holmes. Because Arthur Conan Doyle is the creator and authority on Sherlock Holmes, he was brought to assist the detectives in tricking the man into revealing his true self. However, to Doyle's surprise, the man was an impeccable likeness to his character, offering all logical answers to his questions. Doyle even asked him how "Sherlock Holmes" could have survived his death at the Reichenbach Falls, as there were no footprints leading away from the cliff, but the man replies that he retraced his own footprints. Doyle is startled and admits that it is a good idea. It is suggested that the man gave the ideas that made it possible for Doyle to bring his character back to life.
