Tap gloves and tune in for a quartet of radio mysteries set in and around the boxing ring. First, a crooked gambler is killed when he tries to a fix a fight in "Death is a Knockout" from Crime Club (originally aired on Mutual on June 12, 1947). Next, Dick Powell gives a heel turn as a boxer out to ruin a rival in "Slow Burn" from Suspense (originally aired on CBS on February 23, 1950). Reporter Randy Stone tries to help a fighter under pressure to throw his next bout in Night Beat (an episode known as "Gunner's Last Fight," originally aired on NBC on August 14, 1950). And Jayce Pearson investigates when poison puts a fighter down for the county in "The Rub-Out" from Tales of the Texas Rangers (originally aired on NBC on February 3, 1952).
