Det. Murdoch investigates a robbery of bank safe deposit boxes that were being transferred. The masked thieves make off with two boxes but the driver of their getaway cart is killed. While investigating the scene, Murdoch receives some helpful information - from someone who claims to be Sherlock Holmes. Dr. Ogden determines that he is actually David Kingsley, a one-time mental patient. Regardless, he has the uncanny habit of assessing an individual or a situation much as the fictional Holmes would do in his books. It all leads to a crime that had occurred when Kingsley was just a boy of 13. Written by

The basic notion behind the plot - which concerns a mental patient who insists that he is actually Sherlock Holmes and refuses to accept that Holmes is a fictitious character - is taken from James Goldman
's play, "They Might Be Giants", and to its film adaptation They Might Be Giants
(1971). See more
