exciting story with an interesting background

recommended book with exciting action. Particularly interesting are the descriptions of the country, people, living conditions in India. Good is also the (außergewönliche) Composition of the operation: to constantly change between past / memory and the present (the quiz show). Each chapter is self-contained and describes experiences of the protagonist, which meant that this can answer each question correctly.
The book is a lot better and is different in the plot partly strongly FROM eponymous film !!!!
