Set This House on Fire — William Styron

The day after Peter Leverett met his old friend Mason Flagg in Italy, Mason was found dead. The hours leading up to his death were a nightmare for Peter—both in their violence and in their maddening unreality. The blaze of events which followed was, Peter soon realized, ignited by a conflict between two men: Mason Flagg himself, and Cass Kinsolving, a tortured, self-destructive painter, a natural enemy and prey to the monstrous evil of Mason Flagg. Three events—murder, rape and suicide—explode in the is relentless and passionate novel, almost overwhelming in its conception of the varieties of good and evil.
 
“It may be one of the finest novels of our times . . . Styron, besides being a superb craftsman and a skillful, evocative artist, is a master storyteller.”—San Francisco Chronicle
