Query: Magnificent work

This book is simply brilliant. It is truly deserving of the praise that it has been given. The story of David Race Bannon is a remarkable one. He is not a bigtime spy but rather a naive young man who got caught up with the wrong people in desperation. This book is one that all should read, especially students and travellers such as myself. Race, if you are reading this, your story has influenced far more people that one would ever believe. It has certainly changed my outlook on certain aspects of life. Truly magnificent.
