Mr. and Mrs. North is a radio mystery series that follows the lives of amateur detectives, publisher Jerry North and his wife Pam, who live in Greenwich Village at 24 St. Anne's Flat. Created by Frances and Richard Lockridge, the couple stumbles across a murder or two every week throughout the show, reaching nearly 20 million listeners. Combining elements of mystery and lighthearted comedy, Pam often solves the cases, while her husband Jerry provides the background for their adventures. Mr. and Mrs. North are also featured in 26 novels, a Broadway play, a motion picture, and several television series.

The show was broadcast on CBS from 1942 to 1954, starting with Alice Frost and Joseph Curtin in the title roles. Later on, Richard Denning and Barbara Britton played the Norths. The series aired on NBC Radio for Woodbury Soap from 1941 and December 1942 through December 1946, and then on CBS Radio for Colgate-Palmolive from July 1947 to April 1955. In 1946, Mr. and Mrs. North received the first Best Radio Drama Edgar Award from the Mystery Writers of America, tying with CBS's Ellery Queen.
