By the 20th century, the centuries-old Roman Catholic exorcism ritual for
combatting demonic possession was all but dead, eviscerated by the ascent
of modern science and rationalism. But Ray Russell's 1962 novel, The Case
Against Satan, set the stage for a proliferation of exorcisms on page,
screen, and even bizarrely, in real life.Just a few weeks ago, Susan Garth
was a very good girl, a clean-talking sweet little girl of high school
age. But that was before she started having fits-a sudden aversion to
churches and a newfound fondness for vulgarity. If not madness, then the
answer must be demonic possession, for which there is only one response-
exorcism.
