Night Editor (1946)

"Night Editor" was based on the already existing radio program in which a newspaper editor would recount the 'inside story' of some bit newspaper story, and later became a television series: This time, a night editor of a newspaper is telling a story to a young reporter, who is neglecting his job and wife and beginning to drink too much. The story begins as a police detective, although devoted to his wife and young son, has entered into an affair with a society girl, also married, and while they are parked out in the boonies on a lonely road, they witness a murder. The detective, because of the circumstances of being where he is for the reason he is there, does not attempt to catch the killer and does not report the crime. He is later assigned the case and soon realizes that an innocent man is about to take the blame, and the only way he can clear him is to arrest the killer and become a witness against him. The story-teller also has a vested interest in the old case.
