A Case Of Exploding Insults by Mohammed Hanif

Currently I am reading the latest book 'A Case Of Exploding Mangoes’ by Mohammed Hanif, published by Random House India. Indeed the book is really a good read with a dark and subtle political humor BUT there's one thing that has put me off and that is the derogatory language used against the two great singers of India: Asha Bhonsle and her sister Lata Mangeshkar. The scanned page is given (page 81) . Incidentally this man, the author had been a Pakistani pilot officer, such a language is not expected out of an intellectual who claims to have worked with top newspapers and magazines around the world including a stint at India today as well. Mohammed Hanif must apologize and I wonder why there has been no objection yet? And I also wonder how this manuscript was given an OK by the content editors of the publisher?
