It's four months on from the events of Dust and Desire... Joel Sorrell has recovered from the injuries he sustained in his fight with The Four-Year-Old. A body has been found, sealed into the dead space behind a false wall in a flat in Muswell Hill. Beheaded and surrounded by bloodstained pages of typewritten text, it is the third such murder committed by a killer known as The Hack. And it may be linked to his daughter's disappearance.
