William Gargan played several cops on screen and the radio, but his most famous role may have been Barrie Craig, the sardonic New York shamus who qupped his way through cases for five years on the air. We'll hear Gargan in a pair of mysteries, beginning with "Zero Hour" (originally aired on NBC on February 2, 1954). Then we'll hear "Mid-Summer Lunacy" (originally aired on NBC on August 17, 1954).
