For nearly two decades and in almost 1,700 episodes on radio, kindly old Mr. Keen searched for the missing and pursued the guilty. The grandfatherly gumshoe (played by Bennett Kilpack) and his assistant Mike Clancy (Jim Kelly) are on another adventure of mystery and murder in “The Case of the Absent Minded Professor,” first aired on CBS on March 15, 1945.
