When Anna Warne and ex-detective Ben Elias are asked to investigate a spate of ugly threats and vicious attacks in a sleepy Wiltshire village, they have little idea where the case will lead. But the recent excavation of a nearby mosaic with a possible Arthurian connection suggests there may be more to it than first meets the eye.

A hoard of immense significance is found, yet missing a vital piece. A man is murdered. As the stakes rise, so does the urgency, forcing Anna and Elias to unearth long-buried secrets in their quest for answers, while also drawing closer to a discovery of unparalleled importance.

But it isn’t just the truth they’re fighting for any more. It’s their own survival.
