Remarkably beautiful"" Eve Emerson, daughter of a millionaire Senator, wants a career in journalism--so, posing as a breakfast-maid aboard the QE 2, Eve tries to interview actor Armand Villar, a recluse who's rumored to be the ""Don Juan of the jet set."" But when Armand's naughty lying sets Eve off course, she's furious--until Armand re-enters her life in Paris, whisking her away for lunch and a pond-side picnic. (The ""bullfrogs croaking in the pond and an occasional fish. . . will startle us. . . and cause widening circles on the still water,"" murmurs Armand. ""You're positively lyrical,"" coos Eve.) Meanwhile, Eve is meeting the mother she never knew--now remarried and living with a French baron in wine country, right next door to (wouldn't you know!) Armand's unhappy-childhood home. . . which turned him off marriage forever. Eve is holding out for wedlock, however; Armand comes on strong for a meaningful interlude. (He warns her that she'll end up ""a lonely New England virgin who no man will care to seduce."") Eve's barricades do fall--after she has helped Armand to recover his kidnapped racehorse Azur: they tumble together in a handy cottage, as the ""promise of sleeping and awakening in each other's arms precluded any preliminary byplay."" And though seducer Armand slithers away, there'll be a love-conquers-all fadeout in N.Y.--where the actor is doing bang-up Hamlet business. Dippy and dumb.
