A novel by James Hadley Chase was the source for Une Manche et la Belle (Beauty Up His Sleeve). Bank clerk Henri Vidal ingratiates himself to middle-aged heiress Isa Miranda. Once they're married, however, Vidal's eyes begin to wander. Falling for Mylene Demongeot, Vidal and his new paramour cook up a scheme to knock off Isa and claim her money. But Mylene has an evil agenda all her own. More than one reviewer noted the resemblances between Une Manche et la Belle and the American noir masterpiece Double Indemnity.
