"Thou Art the Man", originally titled "Thou Art the Man!", is a short story by Edgar Allan Poe, first published in 1844. It is an early experiment in detective fiction,[1] like "The Murders in the Rue Morgue", though it is generally considered an inferior story.
The plot involves a man wrongfully accused of murdering his uncle Barnabas Shuttleworthy, whose corpse is missing. An unnamed narrator finds the body, suspects the victim's good friend Charles Goodfellow, and sets up an elaborate plot to expose him. The corpse appears to come back to life and points to the best friend, exclaiming "Thou art the man!" The title and the climactic line refer to the second Book of Samuel and also echo a line from the "Great Moon Hoax".
