House of Mystery is a light mystery and suspense show that would be acceptable for some younger listeners.
The show began as a 15 minute serial, but after almost a year moved to a 30 minute format. Roger Elliot, played by John Griggs and then
later an unidentified actor, was the Mystery Man and your host to The House of Mystery. He leads the listener through a "story telling
session" with kids asking questions about the tale. "Extra thin and tender crisp" Post Toasties sponsored House of Mystery. The listeners
are warned not to give their children coffee and to serve a glass of Wholesome Postum instead. This is a rare mystery show and these are
some of the few episodes known to have survived. This series is not to be confused with Mystery House or Mystery Playhouse, hosted by Pete Lorre.
