It takes a thief to catch a thief (or con man or killer), and Boston Blackie is on the case! The reformed safecracker turned detective uses his intimate knowledge of the underworld to track down dangerous criminals and to clear his name with the irascible Inspector Farraday. We'll hear Chester Morris as Blackie in "The Jonathan Diamond" (originally aired on NBC on June 23, 1944). Then, Richard Kollmar steps in for the syndicated episodes "Uncle Bill Blaine's Legacy" and "Charlie Kingston and the Disappearing Office Building."
