A secluded retreat. A storm closing in. A killer among them.

Detective Lola Harris is persuaded to take a much-needed break in the remote Scottish Highlands. But Ardaig Castle, an exclusive wellness retreat for the rich and famous, has its own dark secrets.

Someone is sending malicious letters to the castle’s employees. The latest, sent to the manager, reads: Why have you employed a killer among your staff?

As a storm rages outside, paranoia spreads within. The castle’s wealthy guests are rattled and old wounds are reopened. Then a body is discovered sprawled on the stone-flagged floor of the castle hallway, limbs twisted at an impossible angle.

Trapped by the weather, Lola must untangle a web of lies, grudges and hidden pasts before the killer strikes again.

Because at Ardaig Castle, not everyone is who they claim to be — and someone will kill to keep their secrets buried.

A tense and unputdownable Scottish crime thriller. Perfect for fans of J.D. Kirk, Ian Rankin, Marion Todd, Alex Gray and Val McDermid.
