How do you capture the devil? How do you contain evil itself? Howard 'Duke' Ellington has done just that: he has imprisoned the devil. By day, the man locked in an upstairs bedroom of Duke's house begs to be let go to see his wife and daughter; by night, the devil appears before Duke to taunt his efforts. Has Howard done the impossible and wonderful, locking the devil away for the benefit of humankind? Or is he in the process of committing a terrible sin, spurned on by madness, having kidnapped an innocent man and is now starving him to death? Who is... the devil at the door?
