Our heroes this week encounter hypnosis and meet those who have fallen under its spell and who have used it to try and conceal their crimes. First, Boston Blackie suspects a woman's murder confession was driven by hypnosis rather than guilt. Then, a woman is hypnotized to help solve a murder in "Cupid Can Be Deadly" from Crime Club (originally aired on Mutual on October 16, 1947). In "The Voice of Darkness," Chandu the Magician investigates a bombing where the eyewitness was hypnotized into losing her memory (originally aired on Mutual on April 14, 1949). And finally, Bob Bailey stars as George Valentine in "Eleven O'Clock" from Let George Do It, where a woman's recent odd behavior may be tied to the experiments of a psychology professor (originally aired on Mutual on July 17, 1950).
