Crime Club was a popular old-time radio show that aired on the Mutual Broadcasting System from December 2, 1946, to October 16, 1947, for a total of 47 episodes. The show was based on the Crime Club book imprint from Doubleday publishing company, which produced many classic detective and mystery fiction titles, including all 50 books of The Saint by Leslie Charteris and Sax Rohmer's Fu Manchu series. The series featured murder and mystery dramas, with a new Crime Club book made available to the public each week.

Each episode was introduced by the series host, The Librarian, portrayed by Barry Thomson and Raymond Edward Johnson. The Librarian would set the scene and begin reading the prologue of each week's book, launching into another thrilling Crime Club tale. The show was produced and directed by Roger Bower, and the episodes were mainly scripted by Stedman Coles and Wyllis Cooper.

In addition to its radio success, Crime Club spawned a 1937-1939 film series by Universal Pictures, with 11 films produced during that time.
