The Uncatchable Mr. Frederic (1946)

A novelist (Renée Saint-Cyr) has created "L'Inssaisissable Frederic" ,some kind of "Gentleman Cambrioleur" such as Arsene Lupin,who loves to steal on the trains (when they enter tunnels) or in the station.He 's got fine techniques and many ways of stealing ,with his piece of luggage or while taking a cast of a wealthy English lady's hand (to latch onto the woman's valuable ring).

Enter BB alias Richard ,played by deadpan Paul -"diaboliques"- Meurisse .His motto might be: "theorizing is all very well ,but..." Pretty soon,Frederic will not be an imaginary character anymore ...for the novelist's idea are pretty good...
