Episode 684 - Mine, All Mine! (Philip Marlowe, The Saint, & Johnny Dollar) Oct 18, 2026

Show notes

A miner's strike can yield silver, diamonds, or even gold…but those valuable finds can also lead to murder as our heroes discover this week. We'll hear a trio of radio detectives investigating cases that bring them to (and sometimes in) treacherous mines to hunt for clues instead of ore. Philip Marlowe hunts for a thief in a Mexican diamond mine in "The Unfair Lady" (originally aired on CBS on June 4, 1949); Simon Templar comes to the aid of a woman with a newly acquired silver mine in "The Saint Goes Underground" (originally aired on Mutual on July 31, 1949); and Johnny Dollar investigates whether a fatal mine cave-in was an accident or murder in the five-part mystery "The Midas Touch Matter" (originally aired on CBS between July 2 and July 6, 1956).

Episode 683 - Gumshoe Guest Stars (Box 13, Green Lama, Richard Diamond, & Johnny Dollar) Oct 04, 2026

Show notes

Before they starred (or sometimes while they were starring) in their own radio detective shows, some actors made guest appearances on other mystery programs. Today we'll hear four of them in the supporting cast instead of the lead role. Before Dragnet, Jack Webb joins a scavenger hunt with Alan Ladd in "The Better Man" from Box 13; Charles Russell takes a break from his work as Johnny Dollar for an appearance in "The Million Dollar Chopsticks" from The Green Lama (originally aired on CBS on June 26, 1949); Gerald Mohr hangs up his Philip Marlowe hat in "The Mike Burton Case" from Richard Diamond, Private Detective (originally aired on NBC on July 5, 1950); and two detectives - Larry Thor of Broadway is My Beat and Stacy Harris of This is Your FBI - co-star with Bob Bailey in "The Big Scoop Matter" from Yours Truly, Johnny Dollar (originally aired on CBS on November 11, 1956).

Episode 682 - Two Gusts of "Red Wind" (Adventures of Philip Marlowe) Sep 27, 2026

Show notes

On September 26, 1948, Gerald Mohr went on the air as Raymond Chandler's private eye in The Adventures of Philip Marlowe. His debut adventure was an adaptation of Chandler's short story "Red Wind." Coincidentally, "Red Wind" was also adapted as the first episode of the 1947 series of Philip Marlowe mysteries starring Van Heflin. It's the only story to air with both Heflin and Mohr starring as Marlowe, and we'll compare their performances with both episodes. Plus, we'll hear Marlowe meet Marlowe as Gerald Mohr guest stars opposite Van Heflin in "The King in Yellow" (originally aired on CBS on July 8, 1947).

Our series of radio detectives played by multiple actors takes us today to Baker Street and four men who donned the deerstalker cap of Sherlock Holmes. First, Basil Rathbone is the great detective in "The Tankerville Club" (originally aired on Mutual on April 22, 1946). Next, Tom Conway steps in as Holmes in "The Adventure of the Horseless Carriage" (originally aired on ABC on February 24, 1947).

This week, we collect ten a day and expenses with the Lyon's Eye(s) and the three actors who played Jeff Regan, Investigator. The gumshoe was first played by Jack Webb in a style not dissimilar from Pat Novak For Hire and he was succeeded in the role by Frank Graham with some pinch hitting by Paul Dubov. We'll hear all three play the role of Regan in "The Too Many Mrs. Rogers" (originally aired on CBS on October 9, 1948); "The Barefoot Boy With Shoes Gone" (AFRS rebroadcast from January 25, 1950); and "The Man Behind the Rod" (AFRS rebroadcast from April 12, 1950).

BONUS - Remembering Peggy Webber Aug 19, 2026

Show notes

In this bonus episode, we salute the late Peggy Webber, who passed away on August 15th at the age of 100. One of the radio era's most versatile performers, she wrote, directed, and acted in thousands of episodes. She sometimes played multiple parts in a single episode, and we'll hear an example of that talent as we enjoy some of her radio performances. First, she's a woman in need of help from Sherlock Holmes and Dr. Watson in "The Adventure of the Tolling Bell" (originally aired on ABC on April 7, 1947). Then, she's both a woman who asks The Saint to find her missing brother and a landlady who loves a bribe in "No Hiding Place" (originally aired on NBC on November 19, 1950). Finally, we'll hear her in one of her well-known recurring roles as Joe Friday's mother in "The Big Speech" from Dragnet (originally aired on NBC on April 19, 1951).
