From this inquiry he returned to England with an international reputation as a detective of the supernatural. With the aid of two disgruntled confederates of the theosophist leader, he had demonstrated the falsity of the foundations on which her claims rested, and had shown that downright swindling constituted a large part of her stock in trade. With redoubled ardor he now plunged into the task of exposing the spiritistic mediums plying their vocation in England, and for this purpose enlisted the assistance of a professional conjurer, S. J. Davey, who was also a member of the Society for Psychical Research. Davey, after a little practice, succeeded in duplicating by mere sleight of hand many of the most impressive feats of the mediums; doing this, indeed, so well that some spiritists alleged that he was in reality a medium himself. Hodgson, for his part, by clever analysis of the Davey performances and of the feats of Davey's mediumistic competitors, brought home to his colleagues in the Society for Psychical Research a lively sense of the folly of depending on the human eye as a detector of fraudulent spiritistic phenomena. His crowning triumph came with his exposure of Eusapia Paladino, the Italian medium who is still enjoying an undeserved popularity on the European continent. But in time even Hodgson met his Waterloo. Sent to the United States to investigate the trance phenomena of Mrs. Leonora Piper, he was forced to confess that in her case the theory of fraud fell to the ground, and as is well known he ended by developing into an out and out spiritist. A few days before Christmas, 1905, he suddenly died in Boston; and, if reports from the spirit world may be accepted, the once-renowned ghost hunter has himself become a ghost, visiting in especial two of his American colleagues, Prof. William James and Prof. James H. Hyslop.[S]
