Lady Bluebeard

CBS Radio Mystery Theater "Lady Bluebeard" is a Mystery from Monday, June 26, 1978.

Raymond Poindexter, an insurance investigator, is sent by his company to call on Luana Pilbeam, 35 and very attractive, because she has been the beneficiary of six now-deceased elderly men, all of whom were married to her for less than two years. Poindexter sincerely believes that she poisoned them all. He becomes convinced she is guilty of murder when he drinks some of her lemonade “with a secret ingredient,” causing both his temperature and heartbeat to rise dangerously.
