Conceived as a replacement for Charlie Chan, John P. Marquand's Mr. Moto thrilled readers before jumping to the big screen in a popular series of movies starring Peter Lorre. The adventures of the Japanese secret agent came to radio in 1951 in Mr. I.A. Moto starring James Monks in new international exploits of the diminutive detective. We'll hear Mr. Moto tackle the mystery of "The Crooked Log," first broadcast on NBC on September 30, 1951.
