Thirteen guests. One killer. No escape. On an island on the coast of Cornwall, cut off from the mainland by the tides for most of the day, thirteen old friends meet at Tregowan Castle for a weekend of revelry. By the next evening only twelve are still alive. Amongst them is a killer - but who? As
a storm traps them on the island and past betrayals and grievances are revealed, nerves fray and friendships begin to fracture. But with no escape and no way of calling for help it's only a matter of time before the killer strikes again. And when everyone is keeping secrets, anybody could be the
next victim... Perfect for fans of Lucy Foley's The Guest List and Agatha Christie.
