THE SHADOW "The Museum Mystery" was adapted by Walter Gibson from his own 08/02/43 NICK CARTER radioplay "Murder in the Crypt" or "Nick Carter and the Jackal God." (Yes, Walter rewrote Nick Carter and Patsy as Lamont Cranston and Margo.)
The title is as it appears in the comic, but the character's name is Mr. Dumptee in the story
