Episode 685 - Spectral Sleuthing (Michael Shayne, Sherlock Holmes, Let George Do It, & Richard Diamond)

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).

With Halloween fast approaching, enjoy this encore episode featuring Sherlock Holmes and Dr. Watson tackling seemingly supernatural foes in four old time radio adventures! We'll hear Tom Conway as Holmes and Nigel Bruce as Watson in "The Adventure of the Black Angus" (originally aired on ABC on October 19, 1946) and "The Adventure of the Carpathian Horror" (originally aired on ABC on April 14, 1947). Then, John Stanley and Alfred Shirley star in "The Case of the Sanguinary Spectre" (originally aired on Mutual on February 8, 1948) and "The Case of the Everblooming Roses" (originally aired on Mutual on May 16, 1948).

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).

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).

With a slight delay, we wrap up our celebration of Batman Day with the concluding chapters of "The Secret of Meteor Island." This Superman radio adventure brought in Batman and Robin to help the Man of Steel hunt for a smuggler whose cargo of radioactive diamonds is wreaking havoc on Metropolis. We'll hear the final installments, originally aired on Mutual between June 24 and July 6, 1948.
