We leave the mean streets of the big cities behind and join four radio detectives in western-themed mysteries - stories of cowboys, horses, cattle, and the wide open spaces. Philip Marlowe hunts for a killer on a dude ranch in “The Dude from Manhattan” (originally aired on CBS on July 2, 1949), and Richard Diamond heads to Oklahoma to prove an accidental death was a well-staged murder in “The Hatpin Murder Case” (originally aired on NBC on September 27, 1950).

As summer winds down and students head back to school, we’ll join some radio detectives as they tackle cases on college campuses.

A murderer is supposedly dead, but someone’s spotted him on campus and it’s up to Richard Diamond, Private Detective to find him in “The Martin White Case” (originally aired on NBC on January 22, 1950). And The Saint returns to his alma mater to find the author of some poison pen letters before his works turn deadly in “Simon Carries the Ivy” (originally aired on NBC on April 1, 1951).
