Each of these old time radio detectives earned their livings as writers. They only dabbled in crimesolving on the side because it was their hobby or because real-life mysteries provided inspiration for their work. We'll hear Glenn Langan as mystery writer and police consultant Barton Drake in "The Coin Collector Mystery," a syndicated episode from Mystery is My Hobby.  Then, Alan Ladd is Dan Holiday - newspaperman turned novelist and amateur adventurer - in "Hare and Hounds" from Box 13. And we'll close with Frank Lovejoy as Chicago reporter Randy Stone in "The Girl in the Park" from Night Beat (originally aired on NBC on February 27, 1950).
