Several great actors gave voice to The Shadow, but today we're shining a spotlight on those stars and their roles outside of the cloak of radio's invisible avenger. We'll hear Frank Readick as a crook in "The Case of the Cincinnati Narcotics Ring" from Gang Busters (originally aired on ABC on September 25, 1948). Then, Bill Johnstone is a newlywed with a secret in "Devoted Couple" from The Whistler (orignally aired on CBS on July 9, 1950) and Lt. Ben Guthrie in "The Cop Killer" from The Line-Up (originally aired on CBS on November 30, 1950). Finally, Orson Welles stars in "The Dead Enchantress" from The Lives of Harry Lime and narrates "The Bed Sheet" from The Black Museum.

Over the long run of the Dragnet radio series, Sgt. Joe Friday (Jack Webb) was paired with four different partners. Each of these cops brought a different energy to the show and had a similar but different dynamic with Friday. We'll hear all four of them in this week's episode. First, Barton Yarborough is Sgt. Ben Romero in "The Big Ben" (originally aired on NBC on March 15, 1951). Then, Barney Phillips plays Sgt. Ed Jacobs in "The Big Almost No-Show" (originally aired on NBC on January 31, 1952). Future Adam-12 star Martin Milner is Officer Bill Lockwood in "The Big Bunco" (originally aired on NBC on April 17, 1952). And Ben Alexander plays Officer Frank Smith - Friday's longest-tenured partner on radio, television, and the big screen - in "The Big False Make" (originally aired on NBC on May 17, 1953).

Tap gloves and tune in for a quartet of radio mysteries set in and around the boxing ring. First, a crooked gambler is killed when he tries to a fix a fight in "Death is a Knockout" from Crime Club (originally aired on Mutual on June 12, 1947). Next, Dick Powell gives a heel turn as a boxer out to ruin a rival in "Slow Burn" from Suspense (originally aired on CBS on February 23, 1950). Reporter Randy Stone tries to help a fighter under pressure to throw his next bout in Night Beat (an episode known as "Gunner's Last Fight," originally aired on NBC on August 14, 1950). And Jayce Pearson investigates when poison puts a fighter down for the county in "The Rub-Out" from Tales of the Texas Rangers (originally aired on NBC on February 3, 1952).
