A madcap romp around Paris surrounds the art students of Montparnasse and the connection two -- Robert Cameron and Peggy Stephenson -- have with the murder of a French private detective. Peggy impersonates a vanished American bride; Robert connives with the Arabs of the Flea Market; Inspector Jolivet has his hands full in keeping track of them and their friends, before the killing and the disappearance unwind. Breathless.
