Hangman (S03E11)

Cecil Fox, a despicable criminal found guilty of murdering Justice Horace Mead, is escorted to the gallows at the Toronto Courthouse. Murdoch, present as a witness, grimaces as Pleasant pulls the lever, sending Fox to his fate. During the autopsy, Ogden discovers an unusual puncture mark on his throat. Intrigued, she leans in closer, only to be startled when Fox's eyes suddenly open! Before she can process the shock, he knocks her out cold and makes a daring escape.
