In the lawless days following the fall of the Khmer Rouge, private eye Vincent Calvino crosses from Bangkok into Phnom Penh — a city struggling to rise from genocide and corruption. Hired to track down a missing American, Calvino finds himself in a Cambodia haunted by ghosts of the past and seduced by the promise of fast money and new sins. As he moves between the seedy bars, UNTAC peacekeepers, and ex-mercenaries trading guns for diamonds, Calvino confronts a truth darker than any crime: in a land where millions have been murdered, individual guilt barely registers. Winner of the German Critics' Award for Crime Fiction and hailed as "political, courageous, and brilliant," Zero Hour in Phnom Penh is a haunting journey through post-war Asia — where justice and survival collide in the humid night.
