The treatment

Jack Caffery, brilliant detective whose past includes his brother disappearing and likely killed by a pedophile next door, is put on a case where a child is missing and increasingly likely to be dead after a pedophile ties a family up and does unspeakable things to the family. In fact, there may even be overlap between the current case and the long ago case of his brother.

The story is intense and fucked up. The families of the child victims are somewhat unlikable, and Hayder writes too many characters to make the reader think they may also be pedophiles. So while it's a well-written police procedural, I am not going to keep reading the series. Child abuse is just too infused into every aspect of the story and I'd rather read something not so depraved.
