Portrait of a Man with Red Hair

This is a terrible story about Harkness, a timid American who travels all over Europe with his etchings as his only friends. While in London, he meets a man at the club who recommends visiting a small town during his holidays. The next 24 hours completely change his life. He made friends with a frightened young woman who is unhappily married and meets a man with red hair, a rich and sadistic man who loves to influence others by hurting them.
