In this fascinating book, first published in 1924, Harry Houdini lays out the evidence that the Spiritualism fad is bunk. The 1920s saw a rise in this religion in the aftermath of the Great War; many families were left grieving and desperate for contact with the beyond, and as ever, grifters emerge to take advantage of their plights.

Harry Houdini considered these people beyond despicable and did everything in his power to prove seances, levitation, dematerialization, spirit photography, and other tricks of the trade were pure bunk--the same sorts of sleight-of-hand he practiced in his own shows, only he made no claim that what he did was 'magic.' His voice comes across as emphatic and genuine. He's a man who, in truth, wants Spiritualism to be real so that he can be in contact with his beloved mother again, or talk with the other deceased friends with whom he developed secrets codes with in case they could indeed communicate with him from Summerland or whatever one wishes to call the next world. He had yet to find such proof.

In this book, he discusses not only how seance tricks are done--sometimes with explanatory illustrations--but also the psychology behind the trickery. In particular, he explores how highly intelligent people can succumb to the delusion--most notably his (former) friend Sir Arthur Conan Doyle--and how Spiritualism can drive people into poverty, insanity, and suicide.

Unlike many century-old books, Houdini's text is highly readable. This is really a fast and fascinating read, and not a short one, either. It's about 300 pages. I'm left with a profound sense of respect for Houdini. His passion and concern ring true. He did good work. ( )
