Suspense is a radio drama series broadcast on CBS Radio from 1942 through 1962. One of the premier drama programs of the Golden Age of Radio, was subtitled "radio’s outstanding theater of thrills" and focused on suspense thriller-type scripts, usually featuring leading Hollywood actors of the era. Approximately 945 episodes were broadcast during its long run, and more than 900 are extant.
One of the series’ earliest successes and its single most popular episode is Lucille Fletcher’s "Sorry, Wrong Number," about a bedridden woman (Agnes Moorehead) who panics after overhearing a murder plot on a crossed telephone connection but is unable to persuade anyone to investigate. First broadcast on May 25, 1943, it was restaged seven times (last on February 14, 1960) — each time with Moorehead. The popularity of the episode led to a film adaptation, Sorry, Wrong Number (1948), starring Barbara Stanwyck.
