Query: Joel Martin: Researcher par excellence!

This amazing book well-deserved the status of New York Times Best-seller. Joel Martin, former skeptic of spirit communication, documents his gradual conversion through communications received from medium George Anderson. If there is a question to be asked, Joel finds it. There is an excellent account of various tests that were devised for Anderson. In Joel's transcripts of radio broadcasts made by the medium, my only criticism was that sometimes Anderson appeared to be asking too many questions of the callers and thus modified his messages from the response. In spite of these flaws, Anderson proved himself able to give accurate names, places and spontaneous comments totally relevant to the inquirer's needs. Joel Martin's WE DON'T DIE is a classic in the history of parapsychology and psychic research. A great read!
