When bestselling horror author Joe Delgado is brutally murdered in Miami, a shocking chain of events unfolds. Four of his contemporaries from the horror fiction fraternity - his friend, Nic Legrand; the American, Matt Myrick; the quiet, reclusive Lindsay Eddowes; and the enfant terrible of horror, Jonathan Wraith - are invited to London to hear Delgado's one last mysterious wish. Curiously, Delgado has instructed them to embark on a Halloween trip to a haunted French chateau. But what is the purpose of their journey - is it a meeting of minds? Is it a publicity stunt? Is it a joke? Or, is it something much more sinister? In a turn of events that sees the four authors trapped in their own real-life horror story, they try to uncover who would have written this story and what script would they write.
