We close out this Halloween season of bonus spooky shows with an encore production of "The Hitchhiker" - Lucille Fletcher's harrowing account of horror on the highway that was later adapted for television by Rod Serling as an episode of The Twilight Zone. We've heard Orson Welles in the 1942 Suspense production of the story; today, we'll hear Welles return to the role of cross-country driver Ronald Adams - the man who encounters the sinister stranger thumbing a ride on the side of the road - in this episode of The Mercury Summer Theatre of the Air (originally aired on CBS on June 21, 1946).
