"Not really an audiobook"
This seems to be merely the audio track from an episode from the History Channel, complete with breaks for commercials and repeated summaries. It doesn't make for a good listen.
As for the content, in order to conform to the series title they needed to transform a complex situation into a simple blunder, as though everything would have turned out all right in Kashmir if only Mountbatten had been more decisive. In place of information they use silly dramatic gimmicks and repetition.
I'd go for Mark Tully's India if you want a short short of Indian history.
