Names and faces he thought he'd left behind in Liverpool resurface in London, bringing Castor far more trouble than he'd anticipated. Childhood memories, family traumas, sins old and new, and a council estate that was meant to be a modern utopia until it turned into something like hell . . . these are just some of the sticks life uses to beat Felix Castor with as things go from bad to worse for London's favourite freelance exorcist.
See, Castor's stepped over the line this time, and he knows he'll have to pay; the only question is: how much? Not the best of times, then, for an unwelcome confrontation with his holier-than-thou brother, Matthew. And just when he thinks things can't possibly get any worse, along comes Father Gwillam and the Anathemata. Oh joy . . .
