BEGONE SATAN! A Sensational Expulsion of the Devil which occurred in Iowa in 1928

Originally published in English by Rev. Celestine Kapsner, O.S.B., 1935.
The film The Exorcist (1973; Director's Cut, 2000), and the book which inspired it were in part based on this actual case of diabolical possession and exorcism, as well as another exorcism which took place in Silver Spring, Maryland and St Louis, Missouri in 1949 involving a 14 year old boy.
