Melissa Craig accompanies her artist neighbor Iris to France, where Iris will teach a two-week course at Philippe Bonard's language and culture centre, while Melissa researches Camisard history for her new thriller. Then a former student plummets down a cliff - on the face of it a tragic accident. But the discover, days later, of a second body in almost the identical spot seems to suggest murder instead. And Melissa, uncovering the strange and violent history of the area, and the past treacheries of a Gestapo infiltrator, finds herself drawn yet again into a present-day mystery.
