Box 13 -- The Professor And The Puzzle

Dan Holiday, the newspaperman-turned-novelist of Box 13, runs an ad promising to go anywhere and do anything for a good story -- and the letters that land in Box 13 never disappoint. In "The Professor and the Puzzle," a deceptively academic riddle pulls Holiday into real danger, where solving the puzzle and solving the crime turn out to be one and the same. Movie star Alan Ladd both produced this syndicated 1948-49 adventure series and starred as Holiday himself.
