Convincing proof the devil does exist and still manifests his presence. Covers diabolical infestation, obsession, and possession. Many famous cases of possession and exorcism, plus a general discussion of the devil. This is one of the best books on the subject of possession ever written. Discusses also Satan at Lourdes—to distract from the apparitions of 1858—and the devices of Satan to deceive us.
