To kick off 2024, we're hitting the road with three old time radio mysteries centered on cars. First, Boston Blackie investigates a ring of car thieves after his girlfriend's wheels are swiped in a syndicated mystery starring Richard Kollmar. Next, the cops hunt a hit-and-run killer in The Line-Up (originally aired on CBS on August 3, 1950). Finally, Jack Webb is on the trail of a gang that strips cars for their parts in "The Big Paint" from Dragnet (originally aired on NBC on October 20, 1953).
