A crooked lawyer has framed a U.S. Senator on bribery charges — and only The Shadow stands between him and a perfect crime. But Lamont Cranston's power of invisibility meets its match when the villain designs a trap that needs no eyes to spring: a room so narrow that two men, arms outstretched, can simply walk toward each other and catch what they cannot see. This is Orson Welles at the peak of his Shadow run, playing the Invisible Avenger with magnetic menace opposite Agnes Moorehead's Margo Lane, in one of old-time radio's most ingeniously plotted thrillers.
