Cloudless skies, blue sea and a horrifying discovery - the most glamorous boulevard on the French Riviera, La Croisette, where the jet-set go to see and be seen, is about to become the backdrop to a disturbing murder enquiry. When another in a series of mutilated bodies is found on the seafront, the newly arrived young magistrate, Cecile Galant, finds herself in charge of an investigation that is not all that it seems...Meanwhile, at his flat in London, Charlie Cashel, an affable but aimless young Englishman, receives a mysterious package which galvanises him into action - a roll of undeveloped film, postmarked "Cannes". Charlie's half-sister, Rosie, was murdered there and her killer never found. When the film is developed it shows only one photograph: a painting of a cemetery in the south of France. To get to the heart of the mystery, the hot, thyme-scented countryside of Provence must be explored as lives and events intertwine with horrific and disturbing consequences.
