Everyone who has seen Charade, the Cary Grant & Audrey Hepburn thriller directed by Stanley Donen, knows the vital role that rare and valuable stamps 
play in that mystery.
Can you name another crime-centered movie in which stamps function as a means of transferring large sums of ill-gotten gains?
Hint: a stamp album has a merely incidental role in this movie set primarily in Paris (as is Charade) but with parts in Menton, Rome, and New York.
Second hint: Jean Gabin, who as a young man was most marvelous in Grand Illusion and Le Jour se leve and Pepe le Moko, here is sixty-five years old and the head of a crime family.
