For our final regular episode of 2021, we welcome Joseph Cotten back to "Stars on Suspense" for two old time radio thrillers, including a Christmas story from "radio's outstanding theater of thrills." First, he's a sideshow performer who's grown tired of his boss's tyrannical behavior in "Carnival" (originally aired on CBS on January 28, 1952). Then, Cotten is first mate on a ship bound for the Canadian Arctic to find a pair of ships lost in the ice in "Arctic Rescue" (originally aired on CBS on December 22, 1952).
