Edgar Allan Poe 
Thou Art the Man 

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 in the Bible.
