Frank Lovejoy starred as Randy Stone, a reporter who covered the night beat for the Chicago Star, encountering criminals, eccentrics, and troubled souls. Listeners were invited to join Stone as he "searches through the city for the strange stories waiting for him in the darkness." Most episodes leaned towards suspense, crime and thriller themes, but Night Beat also featured occasional humorous or sentimental stories. Each episode ended with Stone at his desk as he finished typing a news story based on his latest exploits, and shouting for the copy boy to deliver his story to an editor.Radio historian John Dunning described Nightbeat as a "superior series", carried by vivid writing and Lovejoy's sympathetic performance.
Ripperologist editor Paul Begg offered this description of the series:Broadcast on NBC, Nightbeat ... starred Frank Lovejoy as Randy Stone, a tough and streetwise reporter who worked the nightbeat for the Chicago Star, looking for human interest stories. He met an assortment of people, most of them with a problem, many of them scared, and sometimes he was able to help them, sometimes he wasn't. It is generally regarded as a "quality" show, and it stands up extremely well.
Frank Lovejoy (1914–1962) isn't remembered today, but he was a powerful and believable actor with a strong delivery, and his portrayal of Randy Stone as tough guy with humanity was perfect. The scripts were excellent, given that they had to cover much in a short time. There was a good supporting cast, orchestra and sound effects. "The Slasher," broadcast on 10 November 1950, the last show of season one, has a very loosely Ripper-derived plot in which Stone searches for an artist.
