This book was just what I was looking for: a well-written page-turner.
I realised, when I was about to rate this 4 stars, that that wouldn't be entirely fair. After all, it's unrealistic to expect a book about a dosa baron cum murderer to contain life changing prose or philosophical insights. It never claims to do that. So, if I'm being objective and rating this book purely on a scale of whether it does a good job within its stated genre, the answer is: Yes, definitely.
Not only was this an engrossing read, it is apparent that it has been well researched too. I was not aware of the details of the Prince murder by Rajagopal's henchmen, (perhaps because I didn't follow the news when I was that young), so this read like a thriller, even though it was non-fiction.
I'd have to say that I feel a great deal of admiration for the lady, Jeevajothi, aka Principal Witness 1 - the object of Rajagopal's obsession. It's not easy to find someone with such strong will and morals, especially in the face of such coercion and threats to one's life and safety.
Another thing about the book that I liked - although this might not have been the primary objective of the author - is the backdrop it paints of Chennai; the way the city's evolution has been sketched is very interesting, especially for someone like me, who has spent a good part of my childhood in Chennai.
The descriptions of old time haunts like the Drive-in Woodlands (which is now long gone) evoked a certain nostalgia I didn't even know I possessed.
In short, this book is well worth a read: crisp, well-written and factual.
