The Sealed Book - Old Time Radio (theaterofthemind-otr.com)

The Sealed Book was a radio series of horror and mystery tales aired between March 18 and September 9 of 1945. The melodramatic series began each week after "the sound of the great gong," as the mysterious door to the secret vault is opened - wherein is kept the great sealed book, in which is recorded all the secrets and mysteries of mankind through the ages. Here are tales of every kind, tales of murder, of madness, of dark deeds strange and terrible beyond all belief." Scripts for The Sealed Book were by Robert Arthur, Jr. and David Kogan, who also created The Mysterious Traveler.
