From the back cover: Houdini’s crusade against fraudulent mediums brought him into conflict with Sir Arthur Conan Doyle, the creator of Sherlock Holmes and the spokesman for Spiritualism. And it pitted him against a rogues-gallery of rascals. Among them were Pierre Keeler, who produced ghostly messages on slates; George Valiantine and his shenanigans in the dark; the escape artist Nino; and the Reverend Mrs. Josie K. Stewart, pastor of the Independent Church of Truth and a master of sleight-of-hand. But his prime antagonist was Margery the Medium. “It is your wits against mine,” she told him. Was Margery a fraud? Did she despise Houdini—or admire him for his astuteness and manliness? And was Walter, her late brother, responsible for Houdini’s death? In this compelling history, the full truth about Spiritualism is at last revealed—by none other than Sherlock Holmes himself!
