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).

Catch a plane and begin a daring mission with these four radio super spies and sleuths.

Feathers and fiends are on the agenda this week with four old time radio mysteries involving birds. A crow may foil a killer's plans to get away with murder in "Bird of Death," a syndicated episode of The Haunting Hour. Then, Blackstone, the Magic Detective explains how a canary helped him solve the case of "The Bird of Doom" in a syndicated tale. Bob Bailey investigates when a parrot's owner keels over after the parrot tells him to in "Drop Dead" from Let George Do It (originally aired on Mutual on July 23, 1951). And Sgt. Joe Friday hunts a burglar who also targets pet birds in "The Big Bird" from Dragnet (AFRS rebroadcast from February 1, 1955).

Fur coats are in demand in this week's radio mysteries, as our detectives tackle cases involving the pricey outerwear. First, Dick Powell investigates a fur warehouse fire that may be arson in "Fortune in Furs" from Rogue's Gallery (originally aired on Mutual on December 20, 1945). Then, the cops of The Line-Up hope a fur coat can help them identify a Jane Doe in "The Fur Flaunting Floozy" (originally aired on CBS on September 26, 1951). Finally, Johnny Dollar hunts for 80 stolen mink coats and the thieves who committed murder in their getaway in "The Silver Blue Matter" (originally aired on CBS between May 7 and May 11, 1956).

The golden age of radio meets the atomic age with these four mysteries. First, Bulldog Drummond hunts for missing radium in "Claim Check for Death" (originally aired on Mutual on January 17, 1947). Next, villains plot to wipe out New York with an atomic weapon, and only Mr. I.A. Moto can stop them in "A Force Called X07" (originally aired on NBC on May 20, 1951). The feds try to find the man who's smuggling out secrets of a new atomic bomb in "The Case for Dr. Singer" from Suspense (originally aired on CBS on June 28, 1951). And undercover agent Matt Cvetic has to thwart a Red plan to wiretap an atomic scientist in "The Line is Busy" in I Was a Communist for the FBI.

Sometimes it takes two detectives to crack the case. Fortunately, each of these radio mysteries has a dynamic duo on the scene. First, Mr. Keen, Tracer of Lost Persons and his partner Mike Kelly solve "The Case of the Ruthless Murderers" (originally aired on CBS on October 27, 1949). Nero Wolfe and Archie Goodwin take their final bow on the air in "The Case of Room 304" (originally aired on NBC on April 27, 1951). Sgt.
