If you are intrigued by science fiction, vintage radio and Charles McGraw (I go 3 for 3 with this lineup), you will be interested in this 1950 radio podcast, courtesy of Escape and Suspense! a blog devoted to the enjoyment of the CBS radio show Suspense and its sister show Escape.
These archived programs feature original stories performed by some of the all-time great vintage actors.
