International mishmash from a novel by Doris Hume Kilburn involving American secretary Shirley Jones with handsome, mysterious count Rossano Brazzi in Naples. Shirley's abroad doing research with her boss, an urbane art curator; Brazzi is their host who resides in a cliffside Italian villa. Their rocky first meeting quickly turns to romance, despite an ex-lady friend hanging about, as well as Rossano's unstable daughter, a shut-in who insists to Jones that she's Mrs. Brazzi. French-Italian co-production, distributed Stateside by Universal under the title "Dark Purpose", has enough red herrings and suspenseful clinches to make it mildly enjoyable. Jones gets to be a bit sexier here than in previous films (with the exception of a matronly hairdo); matching up well with Brazzi, Shirley has some sass at the beginning, though her character's declaration of love comes too soon, after which she becomes a simp heroine. Brazzi, who must have been tired of playing Euro-cads by this time, is alternately fatherly and patronizing--to everyone!--but the dark streak in his character suits him well this time. George Sanders is typically pithy as Shirley's boss, and the editing and music score are both up to par. **1/2 from ****
