Detective William Murdoch (Yannick Bisson, Sue Thomas: F.B.Eye) of the Toronto police department pushes the boundaries of Victorian-era criminal science to solve baffling murders in this smart, compelling series. Season 4 pits the kindhearted cop againsta would-be vampire, a costumed killer, and ruthless mobsters, inspiring him to whip up a slew of innovative crime-fighting techniques along the way. But while Murdoch nabs the culprits with the help of politically ambitious inspector Thomas Brackenreid (Thomas Craig, Where the Heart Is) and eager constable George Crabtree (Jonny Harris, Hatching, Matching & Dispatching), he struggles to subdue his feelings for former sweetheart Dr. Julia Ogden (Gemini winner Hlne Joy, Durham County). Nominated for 25emini Awards, Murdoch Mysteries is a good-humored twist on crime procedurals. Guest stars include Victor Garber (Alias, Titanic), Simon Williams (Upstairs, Downstairs), Peter Keleghan (The Red Green Show), and Canadian prime minister Stephen Harper in acameo.
