Harry Houdini 
A Magician Among the Spirits [EPUB ebook] 

This is a book about spiritualism written by a self-professed sceptic. In the opening sentence of his preface, Houdini says, ‘ Gladly would I embrace Spiritualism if it could prove its claims, but I am not willing to be deluded by …..so-called psychics’ He discusses the origins of spiritualism, and describes some of its earliest protagonists. The last chapter is called Magicians as Detectors of Fraud and lays the final groundwork for his conclusion.
