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.
Edgar Allan Poe (born Edgar Poe; January 19, 1809 – October 7, 1849) was an American writer, editor, and literary critic. Poe is best known for his poetry and short stories, particularly his tales of mystery and the macabre. He is widely regarded as a central figure of Romanticism in the United States and of American literature as a whole, and he was one of the country's earliest practitioners of the short story. He is generally considered the inventor of the detective fiction genre and is further credited with contributing to the emerging genre of science fiction. He was the first well-known American writer to earn a living through writing alone, resulting in a financially difficult life and career. (Wikipedia)
