Happy Mother’s Day! We’re celebrating moms with five old time radio mysteries where they play major roles. In “The Case of the Lucky Shilling,” Sherlock Holmes comes to the aid of a woman whose son is wiped out by a crooked gambler (originally aired on Mutual on January 14, 1948), and George Valentine tries to prove that a woman is not an unfit mother in “Problem Child” from Let George Do It (originally aired on Mutual on June 21, 1948). A woman hires Dan Holiday to prove her son’s death wasn’t an accident in “Suicide or Murder” from Box 13, and the mother of an escaped convict wants Richard Diamond to send her son back to prison (originally aired on NBC on October 4, 1950). Finally, the cops of Dragnet are on the trail of a serial shoplifter who only steals clothes for children in “The Big Little Mother” (originally aired on NBC on October 6, 1953).

In this encore presentation, we go back to the summer of 1947 when Philip Marlowe came to the air in his own weekly series with Van Heflin playing Raymond Chandler's private eye. The NBC series featured a mix of original mysteries as well as adaptations of Chandler stories, including the show's premiere episode "Red Wind" (originally aired on NBC on June 17, 1947). A year later, Gerald Mohr would put his own stamp on the character, but these Heflin shows offer a different take on Marlowe and a compelling portrayal in its own right. Along with "Red Wind," we'll hear "The Daring Young Dame on the Flying Trapeze" (July 1, 1947); "The King in Yellow" (July 8, 1947); "Trouble is My Business" (August 5, 1947); and "Robin and the Hood" (August 19, 1947).

Lights, camera, action! This week, our old time radio sleuths are tackling cases connected with the movie business and finding mystery on and off screen. First, "the Lyon's Eye" has to protect a movie star from some unscripted violence. Frank Graham stars in "The Hollywood Story, or H is for the Many Things You Gave Me" from Jeff Regan, Investigator (originally aired on CBS on March 22, 1950). Next, Dick Powell goes west when the head of a movie studio is blackmailed - and later framed for murder - in "The Hollywood Story" from Richard Diamond, Private Detective (originally aired on CBS on August 23, 1953). Finally, a corpse in a seaside amusement park is connected to a silent movie star and the long-ago murder of her husband in "The Silent Queen Matter" - a five-part Johnny Dollar mystery starring Bob Bailey as "America's fabulous freelance insurance investigator" (originally aired on CBS between October 29 and November 2, 1956).

We join Johnny Dollar on a cross-country mystery as our bonus series of serialized adventures continues! Bob Bailey is "the man with the action-packed expense account" in "The Chesapeake Fraud Matter" (originally aired on CBS between October 17 and October 20, 1955), a case that finds Dollar trying to prove if a man marked down as dead five years ago is actually alive and well.

We're celebrating the 105th anniversary of the birth of Jack Webb - one of the faces on the Mt. Rushmore of old time radio drama. Best known for Dragnet, Webb logged many an hour solving crimes on the air as cops, private eyes, and amateur sleuths. We'll hear him as Jeff Regan, Investigator in "The Guy from Gower Gulch" (originally aired on CBS on November 13, 1948) and as Pat Novak For Hire in "Wendy Morris" (originally aired on ABC on May 8, 1948). He solves a Prohibition-era mystery in Pete Kelly's Blues (AFRS rebroadcast of an episode known as "Little Jake" from May 22, 1951), and we wrap up with Webb in his element as Sgt. Joe Friday in "The Big Want" (originally aired on NBC on March 1, 1953).

In honor of April Fool's Day, our radio detectives this week have to contend with some practical jokes and jokers that are anything but funny. Dr. Watson is enlisted to pull a prank on Sherlock Holmes in "The April Fool's Day Adventure," starring Basil Rathbone and Nigel Bruce (originally aired on Mutual on April 1, 1946). Dan Holiday tries to find a deranged jokester before his antics turn deadly in "Death is No Joke" from Box 13. A fake will reading turns into a real crime scene as Philip Marlowe hunts for a killer in "The Last Laugh" (originally aired on CBS on April 2, 1949), and Detective Danny Clover has to find out who killed a celebrated prankster in "Laugh-a-Minute Tyler" from Broadway is My Beat (originally aired on March 14, 1953).

The action is on and off the basketball court this week as Superman battles a hate group that targets a high school team just because of the ethnicities of its players. Clayton "Bud" Collyer stars as Clark Kent and the Man of Steel in "The Knights of the White Carnation," a serialized adventure that aired on Mutual from February 26 through March 18, 1947.

Sound the alarm! We've got fugitives on the lam in these radio mysteries - each with an escape from jail at the center of the story. A convict Boston Blackie put behind bars is out and making his way to Blackie's door in a syndicated mystery, and Richard Diamond, Private Detective suspects an escaped gangster is back in town and settling scores in "The Ralph Baxter Case" (originally aired on NBC on April 26, 1950). The Saint comes to the aid of a young man falsely convicted of robbery who breaks out of prison to clear his name in "No Hiding Place" (originally aired on NBC on November 19, 1950). And the cops of Dragnet have to catch their man a second time after he escapes from custody in "The Big Break" (originally aired on NBC on December 14, 1950).
