A dead cop. A damaged detective.
A copycat killer on the loose.

When the chief suspect in the notorious Peek-a-boo cop killer case blew himself up, almost taking lead investigator DCI Duncan Bone with him, the psychologically damaged detective thought his days on the force were over. But when another PC is abducted and murdered in the same deranged Peek-a-boo fashion, Bone is persuaded to return to lead the new investigation. But as Bone and his team hunt a copycat killer, and with time running out before yet another cop is slain, Bone’s terrifying past returns to tear open old wounds and push him to the very edge of the abyss.

Can DCI Bone end the killing before the killing ends him?

Secrets always surface...

Scotland's hottest summer on record is already too much for DCI Duncan Bone. As if the water shortage wasn’t enough, a body turning up at the bottom of Kilwinnoch’s dried-up reservoir sends Bone to boiling point. With three suspects on the loose and time running out, the Rural Crime Unit needs to find the smoking gun and nail the killer before another victim dies.

Set among the dramatic hills and glens of Scotland's Campsie Fells, What Hides Beneath is a pulse-pounding crime thriller that will keep you guessing right up to the nail-biting, heart-stopping climax.
