Deceit, betrayal and tension abound in this chilling police procedural from dazzling new voice Ashley Dyer.

Sergeant Ruth Lake and DCI Greg Carver are on the hunt for a serial killer who carefully poses his victims and covers every inch of their bodies in intricate, cryptic tattoos. Dubbed the 'Thorn Killer' by the media, the killer uses a primitive and excruciatingly painful thorn method to etch his victims. After many months, a breakthrough feels imminent. Then the killer gets personal: the latest victim - a student found only a week earlier - is staged to look like Carver's wife.

Pushed over the edge, Carver spirals into a self-destructive cycle of booze and risky sex. Now he lies near death, and the unreadable Lake stands over him with a gun. Did she shoot her boss? If not, why is she removing evidence from his apartment, faking the scene?

Ruth, too, is convinced that Carver is holding back: that he remembers more than he admits. Why is he lying? Does he know what she did? How can she hope to unravel the half truths, hidden meanings, secrets and lies at the centre of this investigation when she herself has lied and lied?

Intrigued, the Thorn Killer watches their every move - all the while plotting the next. Can Carver and Lake pull together to catch him before he strikes again? Or will they be held captive by their own web of lies?

Utterly gripping, with a twisting plot that keeps you guessing until the end, Splinter in the Blood is an unforgettable listen that will get under your skin.
