Phnom Penh, Cambodia; the rainy season. When a French man, Hugo Quercy, is found brutally murdered, Commandant Serge Morel finds his holiday drawn to an abrupt halt. Quercy—dynamic, well-connected—was the magnetic head of a humanitarian organization which looked after the area's neglected youth. The Parisian detective soon finds himself buried in one of his most challenging cases yet. Morel must navigate this complex and politically sensitive crime in a country with few forensic resources, and armed with little more than a series of perplexing questions: what was Quercy doing in a hotel room under a false name? What is the significance of his recent investigations into land grabs in the area? And who could have broken into his home the night of the murder? Becoming increasingly drawn into Quercy's circle of family and friends, Commandant Morel will soon discover that in this lush land of great beauty and immense darkness, nothing is quite as it seems.
