After witnessing a murder, an emotionally fragile woman (Anabel Shaw) is committed to a private sanatorium by the doctor (Vincent Price) who did the deed! This thriller is cleverly plotted, though the handling of the novel story is a bit dull. The supporting cast is merely adequate, but Shaw's histrionic performance is convincing, and Price is as suave and creepy as usual in one of his first leading film roles. Some simple visual flourishes are also effectively implemented in a couple of scenes. This is fairly routine as crime dramas come, but it's competently executed; there are worse ways to spend seventy minutes.
