With school back in session, we're visiting the faculty lounge at Madison High with three cast members from Our Miss Brooks in their roles as radio detectives. Gale Gordon sheds the stuffy suit of Principal Osgood Conklin as amateur sleuth Gregory Hood in "Murder in Celluloid" (originally aired on Mutual on July 2, 1946). Jeff Chandler leaves bashful biology teacher Mr. Boynton behind to travel to the Big Easy as Michael Shayne in "The Case of the Model Murder." And Gerald Mohr ditches the accent of French teacher Monsieur LeBlanche as Phillip Marlowe in "The Torch Carriers" (originally aired on CBS on January 7, 1950). Plus, we'll hear all three alongside Eve Arden in an episode of Our Miss Brooks (originally aired on CBS on February 20, 1949).

Sometimes it’s good to be bad, or at least it’s good to hear it when radio detective stars switch sides and play some pretty dastardly villains. We’ll hear four of our favorite on-air heroes star as crooks for a change in episodes of radio’s great thriller anthologies. Howard Duff (Sam Spade) plans his wealthy aunt’s murder in “Backlash” (originally aired on CBS on April 21, 1947); Jeff Chandler (Michael Shayne) is a gangster on the run who coerces a doctor into assisting with his getaway in “Confession” (originally aired on CBS on August 21, 1949); and Gerald Mohr (Philip Marlowe) is a murderer who takes up blackmail in “Warm Reception” (originally aired on CBS on November 19, 1950) - all episodes of The Whistler. Then, Dick Powell (Richard Diamond) is a boxer who seeks deadly revenge against a rival in the ring in “Slow Burn” from Suspense (originally aired on CBS on February 23, 1950).

As summer draws to a close with Labor Day weekend, enjoy this encore broadcast featuring Bob Bailey as Johnny Dollar in episodes where "the man with the action-packed expense account" tries to take some time off from insurance investigating...and finds mystery waiting for him wherever he goes. We'll hear him in "The Lamarr Matter," a five-part adventure (originally aired on CBS between March 26 and March 30, 1956) and "The Ideal Vacation Matter" (originally aired on CBS on September 22, 1957).
