The Demon by Hubert Selby Jr.

Harry White is the man other men want to be: admired by his peers, talented, rich, and desired by countless women. His steady rise to a position of unprecedented influence in a New York investment firm seems inevitable to those who know him, and on the way he acquires a beautiful wife and children. But with every achievement the desire to destroy what is his grows stronger. A demon within drives him to sexual excess, petty crime and eventually murder. The Demon explores the dark side of a man's ambitions with unflinching determination. Harry White's story is a gripping twentieth-century tragedy.
