3x11 - Murdoch Mysteries

Cecil Fox, a hateful reprobate convicted of killing Justice Horace Mead, is led to the gallows at the Toronto Court House. Murdoch, there on witness duty, winces as Pleasant pulls the trap door handle and sends Fox to his maker. When she carries out the post mortem, Ogden notices a curious puncture wound in the throat. Puzzled, she leans in for a better look and Fox's eyes open! Before Ogden can react, Fox knocks her unconscious and runs out.
