Georges de la Fouchardiere 
Poor Sap 

Maurice, a married cashier, meets Lulu, a streetwalker. The sad sack falls in love with her. She, however, is in love with her boyfriend/pimp, Dédé. Together, Dédé and Lulu plot ways to get Maurice to give cash to Lulu, mostly at the behest of Dédé. The ending, at once tragic and comic, led to a classic film version (The Bitch, 1931, D. Jean Renoir).
