Mysteries are hard enough to solve without throwing amnesia into the mix, but that's what our radio detectives have to handle this week. A woman doesn't know who she is, and then drops dead in Jack Webb's office in "The Lady with No Name" from Jeff Regan, Investigator (originally aired on CBS on September 25, 1948). The Saint comes to the aid of a woman without her memory in "The Case of the Blonde Who Lost Her Head" (originally aired on Mutual on November 13, 1949). Dick Powell sings and solves the case of a young man who may have committed a murder and forgotten about it in Richard Diamond, Private Detective (originally aired on NBC on November 26, 1949). And Chicago reporter Randy Stone tries to help a soldier find his memory and his missing wife in Night Beat (originally aired on NBC on July 6, 1951).
