The Knowing — David Graham

"No witches were burnt in the writing of this tale, although the Queen was a little singed at the edges."

Ceri Edwards and two school friends lift the lid on an ancient book of recipes belonging to Betty Williams, a volunteer at the local hospital in Pontypridd, South Wales. Two Kansas City cops step off a flight at London Heathrow and one of them falls to the ground with a painful conviction that there's something evil in the air. United in their destinies, Ceri and the police officers are drawn into a world where prophecies are pitted against invisible forces planning to raze London to the ground and bring down the Royal Family. It all rests with Dai Williams, recently knighted MI5 agent and reluctant hero, to bring some order to the improbable events and to ensure that afternoon tea at The Ritz continues for another 100 years.
