Interesting a previous reviewer said it might be the first film to feature psycho therapy. When I was invalided out of the army through Northfiuelds Hospital not long after the war my psychiatrist recommended I should read the book. Don't think I did. I worked in the Pinewood Story Department later and met Nigel Balchin. He had been in the army but had done better than me - rising to Brigadier General I think. Booze got him alas.

In this or one of his other books he used the words 'Boffin' for scientist and 'back room boys' - words that have gone into the language.

It comes as a surprise watching this to discover that psychiatry, in this country, was in such a state of infancy. Although it was about to be introduced into the NHS, in the early post-war years the insane asylums, where anyone who didn't fit the norm, tended to be tossed still prevailed. The mental effects of warfare were a factor in alerting the authorities to cause and effect more clearly than early childhood incidents, which parents tended to do their best to conceal. So, here we have a film of vital social interest, so intriguing and indeed stunning a 1947 audience that the film receive many plaudits and became the official British entry at Cannes. Burgess Meredith puts in a fine and convincing performance and the entire film is presented in such a way as to titillate, excite and inform with the added bonus of a scary suspense element and killings.

Meredith shines in this underrated film that may be the finest depictions of the profession of psychotherapy ever made. He is first-rate as he portrays a therapist struggling with his personal flaws and profound doubts as to his effectiveness with clients. Exciting, well-written, superbly directed, and excellently filmed by cinematographer Freddie Francis, this will have a special significance to any counselor who has ever wondered if he or she was doing any good for themselves or anyone else. I saw this film first as a young boy and while I did not appreciate the subtleties in the script at the time, I found myself drawn to the character of the therapist. Eventually, I became one myself and perhaps this film planted the seed of interest in psychology and psychotherapy. When a film has that sort of impact, it is nothing less than a treasure.
