Interesting autobiography but not nearly as engaging as Eileen Garrett's. Prompted me to learn more about the Houdini chapters he wrote about; there is an interesting Parapsychology Foundation lecture that provides more balanced color on Arthur Ford from a friend. It's called The Houdini Code Mystery: A Spirit Secret Solved and available on Youtube.
Of most value for me were the chapters near the end of the book on developing ESP abilities, the power of prayer etc.
