Exorcist Reverend Merrily Watkins is challenged bya modern day witch hunt, in her third adventure

When a redundant church is bought by a young pagan couple, the local fundamentalist minister reacts with fury. In an isolated community on the Welsh border, a modern witch hunt begins. Diocesan exorcist Merrily Watkins is expected to keep the lid on the cauldron, but what she finds out will seriously test her beliefs. Also, there's the problem of the countrylawyer who won't be parted from his dead wife; the mystery of five ancient churches all dedicated to St. Michael, slayer of dragons; and a killer with an old tradition to guard."
