It became one of the most shocking films of all time and now it's inspired Fox TV's spine-tingling new television series - for millions of readers, William Peter Blatty's The Exorcist remains the most terrifying novel ever written...

Father Damien Karras- 'Where is Regan?'
Regan MacNeil- 'In here. With us.'

The terror begins unobtrusively. Noises in the attic. In the child's room, an odd smell, the displacement of furniture, an icy chill. At first, easy explanations are offered. Then frightening changes begin to appear in eleven-year-old Regan. Medical tests fail to shed any light on her symptoms, but it is as if a different personality has invaded her body.

Father Damien Karras, a Jesuit priest, is called in. Is it possible that a demonic presence has possessed the child? Exorcism seems to be the only answer...

This edition, polished and expanded by the author, includes new dialogue, a new character and a chilling new extended scene, provides an unforgettable reading experience that has lost none of its power to shock and continues to thrill and terrify new readers.
