Murdoch faces a serial killer-could he be Jack the Ripper?

When Alberta Moffat is found gutted, Murdoch begins to wonder what they have on their hands. They are told by a Scotland Yard detective, Edward Scanlan, that he has been pursuing a suspect, Harlen Orgill, across the Empire. He also suggests that the man may be Jack the Ripper. Moffat worked as a laundress and her mother does not accept the suggestion that she was a streetwalker as well. They soon find a second victim, Gloria Abercrombie, who had recently moved to Toronto. She had no police record and was on her way home after working late at night as a seamstress. Murdoch consults Dr. Roberts in the hope of getting him to prepare a psychological profile of the killer. Using a new invention, an ultra violent light, he finds where the murders took place. He also discovers one thing that both victims had in common. Meanwhile, Dr. Ogden accepts William's invitation to the Dinosaur Ball but there's only one problem: he can't dance.—garykmcd

Scotland Yard detective Edward Scanlan was arrested by Higgins at the bridge where 'decent' prostitute Alberta Moffat was throat-slit, the blood used to write a challenge to the police, before he can identify himself and be released. Brackenreid takes his theory serious the MO points to Jack the Ripper, whom he claims to have chased around the British Empire, always escaping after eight kills, now under the pseudonym Harlen Orgill. He's officially assigned to assist Murdoch, who can't appreciate his haughty temper and abuse of constables and Julia, whose dance school partner William becomes. More murders seem to confirm his theory, but team Murdoch finds holes and the link between the victims before turning on the actual serial killer.—KGF Vissers

For over a year, Scotland Yard Detective Edward Scanlon (Alastair Mackenzie) has been on a worldwide hunt for serial killer Harlan Orgill, and now he predicts Orgill will strike in Toronto. Sure enough, two women are murdered in quick succession. The words 'try to stop me' are found scrawled in blood near the bodies, but further examination of the crime scene suggests that the women were killed elsewhere and moved. Murdoch (Yannick Bisson) discovers that the victims had been lured into a stolen carriage driven by a stranger. When slaughterhouse worker Morris Bailey (Paul Haddad) is found peeping on women in a nearby neighborhood, Scanlon is satisfied that they have their killer. But Murdoch believes the killer is still at large and the trick will be finding the connection between the victims before there's another murder.—Shaftesbury
