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 was the head of a humanitarian organization which looked after neglected youth. The Parisian detective 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? Morel will soon discover that in this lush land of great beauty and immense darkness, nothing is quite as it seems.
