A foot, a hand, and a headless torso have surfaced along the Don River and Dr. Philpott, Ogden’s replacement, insists the body parts all belonged to one murder victim. Murdoch has his doubts about Philpott's opinion and contacts Julia. Ogden, although initially reluctant, can’t help but be intrigued by the case. Murdoch secretly sends her the evidence and Ogden’s examination determines that they are in fact dealing with three different victims - but likely only one killer.
