How about Demons?: Possession and Exorcism in the Modern World (Folklore Today)

"Quite an interesting book... " ―Religious Studies Review

"It is by far superior to anything else on demons we have seen in the past few years." ―The American Rationalist

"... Goodman is to be commended for a stimulating and wide-reaching treatment of a compelling and much-debated subject." ―Journal of Folklore Research

Rich in detail derived from the author's fieldwork and the anthropological literature, this work paints a picture of possession as one of the usually positive and most widespread of human religious experiences. It also details the ritual of exorcism, which is applied when things go wrong.
