For centuries the ceremonial order of the Knights of the Tarasque have met to bear the effigy of a mythical beast through the Provencal town of Taracson. But one summer's night the ceremony is broken by a gruesome discovery: a mutilated body found at the feet of the effigy, apparently torn apart by enormous teeth and claws. Can the monster of legend be more than just myth?

The case draws an unwilling Michel de Palma, of the Marseille murder squad, into the dark heart of a Provence where mythology and untold history are part of everyday life. As more dismembered corpses continue to appear, de Palma falls into a world coloured by murky financial intrigues and the tortured history of post-occupation France. It's a world where de Palma's uninvited investigations could soon see him in mortal danger.
