Mark Sabat, ex-priest, ex SAS-trained killer, exorcist, is a man with a dreadful mission. Driven and haunted, he has to seek out and destroy his mortal enemy. He stood upon twice-holy ground. A country churchyard, consecrated and tended for hundreds of years. But before that, long long before, ground sacred to a dark and bloody religion. A religion most thought long vanished, its otherworldly horror deep buried and forgotten save in the nightmares of the deranged.
