Now, with The Chessmen, Peter May gives us a dramatic conclusion to his award-winning Lewis trilogy. Living again of the Isle of Lewis, the ex-Detective Inspector Fin McLeod is working as a security officer for a local landowner. While investigating illegal activity on the estate Fin encounters the elusive poacher and former childhood friend Whistler Macaskill.

But while Fin catches up with Whistler, the two witness a freak natural phenomenon--a 'Bog Burst'--which spontaneously drains a loch of its water, revealing a mud-encased light aircraft with a sickeningly familiar moniker on its side.

Both men immediately know that they will find inside: the body of Roddy Mackenzie, a friend whose flight disappeared more than seventeen years before. But when Whistler's face appears to register something other than shock, an icy chill of apprehension overtakes Fin. What secret has Whistler been hiding from him, and everyone else on the island? Fin is unprepared for how the truth about the past will alter the course of the future.
