A prominent neurosurgeon relates to his students in medical school a story about an affair he had with a married woman and how, after the affair was over, the woman one day fell out a window and died. The surgeon, suspecting that she was murdered, set out to find her killer--but, instead of turning the suspect over to the police, he planned to take his own revenge on the murderer.

Doctor James Mason involved in a difficult jealousy drama with two women, one his mistress, the other her sister-in-law.
23 February 2015 | by (Sweden) – See all my reviews

This is a very unusual and intelligent thriller, like most thrillers involving doctors usually are. It is the first of James Mason's very few own productions and features his own wife, Pamela Mason, here Pamela Kellino, as the second of the two ladies he is involved with, both of them leading to disaster. The intrigue cleverly leads astray at times while at the same time it sharpens as the doctor (James Mason) finds his own case constantly more crucial. He stages a kind of mock trial with himself by giving a lecture at the medical theatre with all rows filled with young attentive students, and one student almost sees through his show and sharpens his case even further. Is he in control or is he not? Has he the right to judge what's right or wrong or has he not? The film poses many questions, and the questioning becomes increasingly more critical, until in the end he is faced with the final trial as a doctor, when an emergency calls on him to perform one more brain surgery. It's the doctor who assists him who puts him to the final test, and these scenes are the most interesting and important in the film. James Mason as the doctor has no other choice than to be consistent with his own argument and conclude his own case after having received an understated sentence by his elderly colleague. It's a remarkable film, not for its direction, which could have been better, but for its very thought-provoking story with the presentation of a case which not even doctors could in any possible way be called upon to give a fair judgement of. The tragedy of this case is that James Mason, one of the best actors ever, a constantly brooding romantic hero, more Hamletian than Byronic, has no other choice, which probably no one could reasonably disagree with.

In addition, you can't help recognizing some details here from other, later films, that boast its influence, especially Hitchcock's "Vertigo", displaying the identical problem of a man's involvement in two women related with each other, Hitchcock much developing the theme to an equally crucial crisis but in another direction, while the very vertigo scenes Hitchcock must have got the idea of from here.

It should also be noted, that John Monaghan, the script writer, appears as an extra (the truck driver), He made some similar appearances in some films, but this is the only film he wrote, with Mrs Mason as co-script writer. The intrigue with its complications and arguments is so psychologically interesting, that you find more in it each time you see it. For that reason, in spite of its flaws, I will give it a full 10.
