There are two types of crime novel where the stakes are high and so the reader becomes invested in them. Murder and the disappearance of a child.
In this Robinson combines two separate crimes in this slow paced police procedural. A young girl goes missing and a body in a derelict mine chimney. At first there isn't a connection but as the book gets going they become linked.
Robinson doesn't try to disguise the fact there are similarities to the Moors Murders in the UK in the sixties, and some scenes in this novel some readers could find distressing.
Although slow paced, as the book draws to its conclusion there is a certain urgency that Robinson injects into the final chapter, there is a sense of relief at the end but with plenty of unanswered questions which will make you think.
