'Few writers blend the ancient and supernatural with the modern and criminal better than Rickman.' - Guardian Diocesan 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 mum - 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.
