Down These Mean Streets (Old Time Radio Detectives)

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.

Holy team-up! To celebrate Batman Day, here's a radio adventure that unites the Caped Crusader and Robin, the Boy Wonder, with Superman. We'll hear the heroes join forces in the first eight chapters of "The Secret of Meteor Island" (originally aired on Mutual between June 14 and June 23, 1948). Stay tuned later this week for the final chapters of this thrilling super story!

As a new school year gets underway, we head to Yale for the exploits of star athlete and adventurer Frank Merriwell. The all-American hero first appeared in pulp novels and later came to radio and the big screen with stories of derring-do on and off the field. We'll hear some of his adventures with Lawson Zerbe starring as Frank: "The Clue of the Numbers" (originally aired on NBC on October 19, 1946); "The Stolen Masterpiece" (originally aired on NBC on June 5, 1948); "The Unwelcome Rescue" (originally aired on NBC on July 3, 1948); and "The Live Ghost" (originally aired on NBC on September 11, 1948).
