The Long Goodbye by Raymond Chandler (1953). Chandler’s sardonic and chivalric gumshoe Philip Marlowe winds up in jail when he refuses to betray a client to the Los Angeles police investigating the murder of a wealthy woman. Marlowe’s incorruptibility and concentration on the case are challenged even more when the obsessively independent private eye falls in love, apparently for the first time, with a different rich and sexy woman. She proposes marriage, but he puts her off, claiming he feels “like a pearl onion on a banana split” among her set.
