After his debut book, the excellent Eating the Flowers of Paradise, Kevin Rushby has set himself a very hard act to follow. The author is now on less well-known territory as he sets out to trace the origin diamonds in India, in particular the world famous Koh-i-nor diamond. True to his adventurous spirit, he soon ventures off the beaten track in Southern India, where he injures his elbow in a bus crash in which the passengers force the bus driver to continue the journey despite causing the crash through his falling asleep, because 'it is his duty'. This book has a sense of crime fiction about it, as the author investigates through various channels where diamonds were historically mined. He encounters many people who appear unprepared to talk about diamonds, and has difficulties being unable to speak the local language, but manages to ascertain that there is some small scale prospecting and possibly illicit dealing taking place. While journeying northwards, he meets many colourful Indian characters, takes part in a Jain pilgrimage and goes in search of the rare and endangered Asian lion with a former maharajah. The story, packed with historical insights into India, takes a surreal twist when the author is mugged and drugged in Delhi, which he accepts so philosophically that the reader is obliged to remind himself that he is reading factual travelogue and not crime fiction. This book takes you well off the tourist trail and puts things in an enlightening historical context. The author does not attempt to make this into an adventure travel book, but he scratches below the surface of Indian life while being culturally sensitive, and his modesty ensures a refreshing lack of hyperbole.
