After Me Comes The Flood

One hot summer's day, John Cole decides to leave his life behind. He shuts up the bookshop no one ever comes to and drives out of London. When his car breaks down and he becomes lost on an isolated road, he goes looking for help, and stumbles into the grounds of a grand but dilapidated house. Its residents welcome him with open arms - but there's more to this strange community than meets the eye. They all know John by name, they've prepared a room for him, and claim to have been waiting for him all along. Who are these people? And what do they intend for John?
