An Outcast Of The Islands by Joseph Conrad

A troubled, opportunistic European in the Malay Archipelago manipulates and betrays those around him—both European and native—through deceitful business dealings and illicit relationships; as his lies and selfish choices unravel, he becomes increasingly isolated, haunted by guilt and superstition, and ultimately cast out by the community he exploited, a portrait of moral collapse and the alienation wrought by colonial ambition.
