With Valetine's Day right around the corner, we're celebrating with three crimesolving couples from the golden age of radio. First, in "A Crime to Fit the Punishment" from The Mollé Mystery Theatre, an amateur sleuth and his girlfriend investigate a strange case of blackmail (AFRS rebroadcast). Next, it's another adventure of the Duke and Duchess from Murder By Experts - the locked room mystery "The Unseeing Witness" (originally aired on Mutual on September 26, 1949). Finally, we'll hear Les Damon and Claudia Morgan as Pat and Jean Abbott - an insurance investigator and his sharp-eyed wife - in "The Fabulous Emerald Necklace" from The Adventures of the Abbotts (AFRS rebroadcast).
