Made [from the novel by James Hadley Chase] by an American director in Italy using English, with French producers and French, British and Italo actors, this is a sleek, mannered look at an affair between a cold, almost psychotic, call girl and a writer, who is a fraught with overtones of masochism.
A blustering, self satisfied British writer, who has a bestseller and smash pic under his belt, has also amassed an Italian fiancee and lives in Venice and Rome. His film producer suspects him and, being in love with his fiancee, is having him investigated.
He has to come up with another story, and goes off to a posh secluded house on an isle near Venice. A broken rudder had let a boat in with an enigmatic, hard-looking French girl and an older man. They had broken into the house and she was calmly in the bathtub when the writer comes in. He wants to throw them out until he ogles the femme.
He throws out the older man who had paid off the girl in paintings for a night of love. The writer tries to get next to her but she knocks him cold with an ashtray. Thus starts an obsession.
Picture is reminiscent of pre-war Yank femme fatale films. But there is not enough character to give acceptance to the over-indulgence in Jeanne Moreau as the cold-hearted harlot. Moreau speaks good English but is hampered by the over-decorated, over-stylized vamp she is called on to play. Stanley Baker acquits himself acceptably as the climbing ex-coal miner, and others are adequate.
