Riveting psychological thriller. Kimberley (Baxter) returns to her isolated seaside villa following roadside death of her brother. Trouble is a guy (Todd) turns up claiming he's the dead brother, Ward. It should be easy to expose the imposter, she figures. Except it's not. His face turns up in family albums, while he seems to know all about their past as brother and sister. So what's going on. No matter what she does, even with the police inspector (Lom), she can't disprove his claim. Now she's beginning to doubt her sanity. But who will help her in this isolated seaside spot.
Actress Baxter has a well-known tendency to over-emote. Here, however, she delivers a carefully restrained and shaded performance in the pivotal role. Add British actor Todd as the impassive, slightly sinister, Ward, along with a tight suspenseful script that cleverly unfolds, and you've got a good slice of A-grade entertainment. Those who've noted a resemblance to standard Hitchcock fare are on target.
There're a few tense high spots—the reckless race over the seaside road, the sleight-of-hand with incriminating liquor glasses, Kimberlie's hide-and-seek escape from the house. But just as magnetic is the general mood of subtle menace, as we wonder exactly what's going on. And, oh yes, the twist ending that's something of a stretch, yet satisfying nonetheless. All in all, the movie's a neo-Hitchcock sleeper, well worth catching up with.
