As to whether communication with the departed is possible, no discussion is here attempted. The episodes following, from experiences well authenticated, merely illustrate what sleight-of-hand experts have long known -- that most "mediums," "astrologers," "mind readers," and the like, can be proven to be frauds. Their dupes are puzzled, and sometimes won over, in the name of Spiritualism, either by the tricks familiar to all "conjurers," or else by the psychology of deception. Some of the cleverness displayed is marvelous, as the following pages show. Included are chapters on "The Methods of a Doctor of the Occult," "The Name of the Dead," "Mind Reading in Public," and "Some Famous Exposures."
