The October Man
When a bus crashes due to faulty steering, passenger Jim Ackland (John Mills) sustains a serious brain injury and a young girl under his care is killed. Guilt ridden, he attempts suicide twice during his recovery.
He starts a new job as an industrial chemist and gets a room in a hotel. When he reluctantly accepts an invitation for a night out, he meets Jenny Carden (Joan Greenwood), the sister of his co-worker, Harry (Patrick Holt). They begin seeing each other quite regularly. Things reach the point where he confesses he wants to marry her, but he tells her he wants to be sure he has fully recovered first.
Molly Newman (Kay Walsh), one of the other hotel residents, asks to borrow £30 from him, a rather substantial sum. As he doesn't have that much on him, Jim good-naturedly writes her a cheque. She is found strangled the next night. Wilcox (Jack Melford), a married businessman Molly had been seeing, has an alibi. Jim admits to have been walking in the vicinity of the murder site; that plus the recovered cheque from the crime scene and his head injury make him the prime suspect. Police Inspector Godby (Frederick Piper) suspects he was another of Molly's boyfriends and that, after falling in love with Jenny, he wanted to rid himself of a possible blackmailer.
When Jim learns that Mr. Peachy, the person who lived in the room directly below Molly's, had told the police that Jim was in her room every night, Jim confronts him in his room. Peachy brazenly admits killing Molly, confident that there is no evidence against him. Peachy had regularly given her money; when Jim made her a loan, it had given rise to an insane jealousy, with fatal results.
Jim goes to the police, but they do not believe him. When they come to take him into custody, Jim flees. He follows Peachy to Paddington Station, then discovers from a tag on Peachy's luggage that he intends to flee the country by plane. He phones Godby with the flight information, but when that appears to have no effect, contemplates suicide again. Fortunately, a letter Molly had posted to Wilcox just before her death incriminates Peachy who's arrested. Jenny finds Jim and gives him the good news.
