S03:É05 - S03:E05 - The Knife

While fighting a T-Rex, Malone and Challenger discover a strange campsite with a macabre raptor display. When Malone picks up a nearby knife, he suddenly becomes John Netley, a coachman in 1888 East End suspected to be infamous serial murderer Jack the Ripper. Challenger suggests that Malone's time in the spirit world has given him psychic abilities, giving him insights at the touch of an object. Back at the treehouse, a stranger appears and may be the notorious owner of the knife. Believing that Jack the Ripper may be at large on the plateau, Challenger encourages Malone to use his new abilities to solve the age-old mystery, and Malone envisions his friends as the historical conspirators and victims in the case.
