On a Sunday night in a south London pub, an appalling atrocity takes place, another in a recent series of similar incidents. Meanwhile Michael Dwight is taking a holiday against his will, and about to meet one of the most dangerous souls in history. And a man called Mervyn Spip is about to attempt to summon The Devil, in Peckham. All of these incidents will soon collide in a whirlwind of adventure, fear, nudity and an awful lot of biscuits.
