On Sunday, October 20th, 1957 at 4:35PM eastern time, the just-heard Agnes Moorehead starred for the seventh time in Suspense’ adaptation of Lucille Fletcher’s harrowing story, “Sorry, Wrong Number.”

In this play, a bed-ridden invalid, attempting to call her husband, accidentally overhears a plot between two men to kill some woman thanks to crossed phone lines. Over the course of the story she desperately attempts to get uninterested phone operators and policemen to care, until she finds out who the intended really victim is.

It is, quite possibly, the most famous thriller in radio history. Ms. Moorehead played this part eight times in the years Suspense was on the air.

This particular adaptation co-stars a who’s who of radio veterans, including Jeanette Nolan, Virginia Gregg, and Byron Kane.
