Suspense anthology series hosted by Orson Welles who asks the audience to solve the crime presented in the first part of each episode. The second part is a separate horror or thriller story with a twist.

Two half-hour series were combined to make this series. Host Orson Welles provided narration and clues for the home viewer. In the first half hour, the viewer was presented a mystery and asked to solve it, with Welles explaining the clues at the end. The second half hour was generally a suspense tale with a surprise ending.—Peter Harris
