It's a fine example of the way Preminger, on occasion, managed to deflect routine melodrama into something more personal and profound.

There is no doubt that people will do strange things under hypnotic spell and that the techniques of hypnotism may be villainously employed. But you don't catch this fairly rational corner believing for one minute the hocuspocus that goes on.

Preminger's ambiguous relation to his characters and his sense of moral relativity have seldom been put to such haunting use.

A film that keeps me hooked for an hour and a half by combining police film noir and psychological thriller with a twisted plot about hypnotism, blackmail and murder. [Full review in Spanish]
