Ride along with some old time radio police detectives and their real-life counterparts in these mysteries. First, Joe DeSantis is Captain Jim Scott, searching for a missing convict and finding a murder in Under Arrest (originally aired on Mutual on November 7, 1948). Next, Dan Duryea is Lt. Lou Dana - the cop who doesn't like killers - in The Man from Homicide (originally aired on ABC on August 6, 1951). And finally, three retired New York detectives try to solve a fictional crime with a cast of radio actors as suspects and witnesses in "Cops and Robbers" from The CBS Radio Workshop (originally aired on CBS on March 16, 1956).
