Ice is in the air - and on the ground - as many parts of the country contend with winter weather, but in this week's show our heroes contend with a different kind of ice...and it's because that ice has gone missing. Detectives hunt down stolen diamonds in these four radio mysteries, beginning with Richard Kollmar as Boston Blackie in a syndicated episode where diamonds are stolen right from under his own nose. Next, Richard Diamond, Private Detective is blamed when several thousand dollars of stones are pilfered from the police commissioner (originally aired on NBC on November 12, 1949). Then, Sgt. Joe Friday is on the case when a diamond salesman is robbed of his merchandise in "The Big Impression" from Dragnet (originally aired on NBC on August 7, 1952). And finally, John Lund stars as Johnny Dollar as he searches for a stolen yellow diamond in "The Uncut Canary Matter" (AFRS rebroadcast from February 16, 1954).

The radio adventures of The Saint premiered in January 1945, and we're celebrating the anniversary of his radio debut with four tales of Simon Templar. Several actors played the Saint over the years, but the voice that's synonymous with the character belongs to Vincent Price, and he plays "the Robin Hood of modern crime" in our quartet of crimes: "The Saint Goes Underground" (originally aired on Mutual on July 31, 1949); "The Problem of the Peculiar Payoff" (originally aired on NBC on July 9, 1950); "Reflection on Murder" (originally aired on NBC on August 13, 1950); and in his final radio performance as The Saint in "Pin No Roses on My Corpse" (originally aired on NBC on May 20, 1951).

We kick off 2025 with a radio recreation of one of the all-time great mystery films and a birthday salute to its star. Dana Andrews reprises his role as a detective obsessed with the woman whose murder he's investigating as The Lux Radio Theatre presents "Laura" (originally aired on CBS on February 6, 1945.) Then Andrews plays another cop on the trail of a killer in "The Crowd" from Suspense (originally aired on CBS on September 21, 1950), and finally he's undercover agent Matt Cvetic in "Courier for Disaster" - a syndicated adventure from I Was a Communist for the FBI.
