When a blind, retired dentist is run down by a logging truck as he crosses the road to post a letter, Dr Siri Paiboun, official & only coroner of Laos, finds himself faced with his most explosive case yet. The dentist`s mortal remains aren`t nearly as intriguing as the letter in his pocket. Written in invisible ink & encrypted, the letter presents Dr Siri with an irresistible challenge. Enlisting the help of his old friend, Civilai, now a senior member of the Laos politburo; Nurse Dtui (` Fatty`); Phosy, a police officer; & Aunt Bpoo, a transvestite fortune-teller, Dr Siri soon finds himself on the trail of an international plot to overthrow the government of Laos.
