The book starts out well and engages the reader with insights into the court of Maharajah Ranjit Singh of Punjab through colonial British eyes. It sets the scene well enough and gives the reader some kind of picture for the ways things were in the court of Lahore, the demise of the kingdom after Ranjit Singh's collapse and the taking to England of Duleep Singh.
Thereafter the book plunges into the deep intricacies of French, Russian, British, American, Irish, German (and more) spying activities, with barely tangible relevance to the story of Duleep Singh. Admirable though the volume of detailed research is, the author forgot that the reader was not with him when he did his research. The book is filled with incidental details involving characters who simply fleet in and out of the book. When the book has hundreds of such characters, how does the author expect the reader to remember on page 302 a character that was last mentioned (briefly) on page 24?
The author would have done better to stick to the story of Duleep Singh in a more confined context than every nuance of the Great Game in nineteenth century politics. It was apparent that the author was very intrigued by the discoveries he made during his research. He made the mistake, however, of sharing every miniscule scrap of information with the reader. The result? A confused narrative, leaving the reader exhausted and glad that the end had finally arrived.
I would also concur that the author failed to take a neutral stance, let alone one sympathetic to the Sikh claims for sovereignty. Doubtless Duleep Singh was a deeply flawed character - a fool even - but the author's tone reflected the precise mocking nature of the India Office correspondence that was his research material. The fact, for example, that Duleep's children maintained a defiant nature against the British was merely mentioned rather than explored. Sikh sentiments - a key ingredient in the real story of Duleep Singh - received scant regard in this book.
The result is, sadly, disappointing.
