A young woman killed in a hit-and-run. A naked body in the cemetery. A local woman reported missing.

A young mother-to-be out for an evening jog is callously struck down in a hit-and-run.

Three weeks later, Detective Mike Nash is called out to the local cemetery. A naked body has been found — a body which definitely shouldn’t be there — placed face down on a grave.

The post-mortem reveals that the victim was restrained with manacles, and then drowned, his body kept upside-down in water for several days after death.

It’s soon established that the dead man was Andrew Derrick, who worked for a local IT company. Quiet, well-mannered, he kept himself to himself. The motive for his murder is a mystery.

Then a second body turns up in the cemetery, killed in the same macabre way. And another employee from the company is reported missing.

What connects them? DI Nash pieces the clues together . . . and finds himself on the trail of a ruthless killer who will stop at nothing to ensure the truth remains hidden.
