It takes a lot of effort for Jimmy Crocker to become Piccadilly Jim - nights on the town roistering, headlines in the gossip columns, a string of broken hearts and breaches of promise. Eventually he bacomes rather good at it and manages to go to pieces with his eyes open.?But He then falls in love with the girl he has hurt most of all, and after that things get complicated. In a dizzying plot, impersonations pile on impersonations so that (for reasons that will become clear, we promise) Jimmy ends up having to pretend he's himself.?Piccadilly Jim?is one of P.G. Wodehouse's most renowned early comic novels, and has been filmed three times.
