BOOK 6: CHILD BEHIND THE WALL
4 a。m。 A police squad descends on a house， eager to catch a burglar in the act。 Nothing could have prepared them for what they find。 From inside a room on the ground floor comes the eerie sound of a woman singing: “the childmaker 。 。 。 the childmaker 。 。 。 beware the childmaker。” The officers break down the door。 They see the body of a man with a knife in his chest and a bloody mess where his face should be。 Nearby stands a small， thin woman。 In her hand is a kitchen knife。 But what is bricked up behind the wall is far， far worse。

BOOK 7: HIS MOTHER’S BONES
Christine Lord， a judge， is tethered to a court roof。 And sentenced to death。 By her own son。 Her ribs are splayed， her lungs lifted out， in an ancient Viking ritual known as the Blood Eagle。 Performed while the victim is still alive。 And now someone else has been left like this in a local London park。 The dead man is someone with very close ties to Detectives Paterson and Clocks。

BOOK 8: DEAD ON DELIVERY
Morning rush hour。 The police pull over a motorcycle courier for a trivial offence。 He doesn’t stop。 The police give high-speed chase。 He jumps a red light and is mown down by an oncoming car。 Killed on impact。 Detectives Paterson and Clocks arrive at a scene of carnage。 Large plastic boxes are scattered around the body， their contents warming up in the early morning sun。 The detectives take a closer look at the boxes。 It’s one of the worst things they’ve ever seen。 And they’ve seen some very bad things。
