"_Our_ hands are clean," Sir A. C. Doyle retorted to my charge of fraud. That is precisely what they are not. Spiritualists have from the beginning covered up fraud with the mantle of ingenious theories, like this "grey" theory. Fifty years ago (1873) a Mr. Volckmann, a Spiritualist, grasped "Katie King," the pretty ghost who had duped Professor Crookes for months. He at once found that he had hold of the medium, Florence Cook; but the other Spiritualists present tore him off, and put out the feeble light; so Florence Cook continued for seven years longer to dupe Spiritualists, until she was caught again in just the same way in 1880. From the earliest days of materializations there were such exposures, and the Spiritualists condoned everything. The medium, they said, when the identity of ghost and medium was too solidly proved, had acted the part of ghost unconsciously, in a state of trance. The ghosts had economized, using the medium's body instead of making one. Some even said that the ghost and medium coalesced again (to save the medium's life!) when a wicked sceptic seized the phantom. Some said, when gauzy stuff, such as any draper sells, or a curl of false hair, was found in the cabinet, that the spirits had forgotten to "dematerialize" it. Some laid the blame on "wicked spirits" who got snow-white mediums into trouble. Some learnedly proved that thoughts of fraud in the mind of sceptics present had telepathically influenced the entranced medium! These things are past, Sir A. C. Doyle may say. Not in the least. In the decade before the War exposures were as frequent as in the palmy days of the middle of the nineteenth century, and Spiritualist excuses were just as bad. Craddock, the most famous materializing medium in England, who had duped the most cultivated Spiritualists of London for years, was caught and fined £10 and costs at London in 1906. Marthe Beraud, the next sensation of the Spiritualist world, was caught in 1907, and had to be transformed into "Eva C." Miller, the wonderful San Francisco maker of ghosts, was exposed in France in 1908. Frau Abend, the marvel of Berlin and the pet of the German Spiritualist aristocracy, was exposed and arrested in 1909. Bailey, the pride of the Australian Spiritualists, was unmasked in France in 1910. Ofelia Corralès, the next nine days' wonder, passed among the black sheep in 1911; and Lucia Sordi, the chief medium of Italy, was exposed in the same year. In 1912 Linda Gazerra, the refined Italian lady who had duped scientific men and the Spiritualist world for three years, came to the same inevitable end; and Mrs. Ebba Wriedt, the famous American direct-voice medium, met her disaster in Norway. In 1913 it was the turn of Carancini; in 1914 of Marthe Beraud in her new incarnation, "Eva C."
