Query: First book in a series that leaves you hungry for more.

Thank you Colin Cotterill for writing about Crime in a newly born Communist Country. Travel back to the Vietnam Era and to Laos and feel right at home with your guide Siri (the Coroner). Siri is a 72 year old Doctor of Medicine who is appointed Coroner because nobody else has the Credentials for the position. Siri is a great character; funny, caring and I am keen to learn more about him in the rest of the Series
