Thailand is terrified. A sadistic serial killer has been abducting young innocents for his ritual horror and the authorities are clueless. Carl Engel is an enigma. The blunt Londoner has forged a thirty-year career as a private investigator amid the chaos of Thailand's political history. Struggling with advancing years and a decreasing workload he is approached by an elderly American with a lucrative missing persons case. The case descends into the sordid world of the elusive serial killer and a menacing web of political intrigue dating back to the Vietnam War. Carl must use his guile and experience to stay alive, find the killer and negotiate the dangerous military interests that lurk behind the scenes. Based on a real person Carl Engel lives in a world rarely seen by outsiders and hauls the reader on a pulsating ride to the explosive conclusion.
