Reverend Merrily Watkins finds herself replacing a retiring exorcist who is determined to make the transition as unpleasant as possibleDiocesan Exorcist: a job viewed by the Church of England with such extreme suspicion that they changed the name. It's Deliverance Consultant now. Still, it seems, no job for a woman. But when the Bishop offers it to Merrily Watkins, parish priest and single mother, she's in no position to refuse. It starts badly for Merrily and gets no easier. As an early winter slices through the old city of Hereford, a body is found in the River Wye, an ancient church is desecrated, and signs of evil appear in the cathedral itself, where the tomb of a medieval saint lies in pieces.
