Three crimesolving couples take the stage this week, beginning with Pam and Jerry North who find a new mystery as soon as they get home from vacation. Joseph Curtin and Alice Frost star in "Wheel of Chance" from Mr. and Mrs. North (originally aired on CBS on June 9, 1953). Next, the Abbotts discover a new mystery on a voyage to London. Les Damon and Claudia Morgan play Pat and Jean in "The Dead-White Lifeboat," an Armed Forces Radio Service rebroadcast of The Adventures of the Abbotts. And finally, ex-cop turned private eye Johnny Duke and his wife Susan (aka "Duchess") have a case drop into their laps in the back of a taxi in "Two Can Die as Cheaply as One" - a story from the anthology series Murder by Experts (originally aired on Mutual on April 17, 1950).
