Laos, 1976. The monarchy has been deposed, the Communist Pathet Lao have taken over. Most of the educated class has fled, but Dr Siri Paiboun, a Paris-trained doctor remains. And so this 72-year-old physician is appointed state coroner, despite having no training, equipment, experience or even inclination for the job. But the job's not that bad and Siri quickly settles into a routine of studying outdated medical texts, scrounging scarce supplies, and circumnavigating bureaucratic red tape to arrive at justice. The fact that the recently departed are prone to pay Siri the odd, unwanted nocturnal visit turns out to be an added bonus in his new line of work.But when the wife of a party leader turns up dead and the bodies of tortured Vietnamese soldiers start bobbing to the surface of a Laotian lake, all eyes turn to Siri. Faced with official cover-ups and an emerging international crisis, the doctor enlists old friends, village shamans,forest spirits, dream visits from the dead - and even the occasional bit of medical deduction - to solve the crimes.
