Happy Father’s Day! We’re celebrating dear old Dad with a collection of radio mysteries featuring fathers. First, Ellery Queen and his police inspector father collaborate on a case of smuggling and murder. Larry Dobkin is Ellery in “Number Thirty-One” (originally aired on NBC on September 7, 1947). Next, George Valentine is hired by a convicted killer's son to clear his father’s name. Bob Bailey stars in “The Father Who Had Nothing to Say” from Let George Do It (originally aired on Mutual on September 13, 1948). Then, meet private eye Joshua Sharp - known to his kids as The Big Guy. Henry Calvin plays the shamus and doting dad in "The Unheard Voice" (originally aired on NBC on May 7, 1950). And finally, Philip Marlowe hunts for a missing son for an ailing father. Gerald Mohr plays Marlowe in “The Last Wish” (originally aired on CBS on July 19, 1950).

Our run through the serialized adventures of Johnny Dollar brings us to the Big Easy! In “The Valentine Matter” (originally aired on CBS between October 31 and November 4, 1955), Johnny’s on a case in New Orleans when he runs across one of Prohibition’s most notorious bootleggers - a man who’s been marked for death by some old enemies.

“Get this and get it straight!” We’re celebrating Gerald Mohr - the radio actor who brought a two-fisted intensity to Philip Marlowe - in honor of his birthday on June 11. He was one of the best stars of the era, and his performance makes The Adventures of Philip Marlowe one of the best detective dramas of the day. We’ll hear Mohr as Marlowe in “The Easy Mark” (originally aired on CBS on January 29, 1949) and “The Long Arm” (originally aired on CBS on February 7, 1950). Then, he’s a less scrupulous character in “Lady with a Key” from The Whistler (originally aired on CBS on April 2, 1950). Finally, he co-stars with Jack Benny in “A Good and Faithful Servant,” a story of a $50,000 department store heist and the mild-mannered clerk who pulls it off, from Suspense (originally aired on CBS on June 2, 1952).
