What is it about 'The Doctor in the House?'

I have asked one of my friends who is going back to Malaysia for a vacation to buy and help bring for me a copy of Tun M's memoir, the 'Doctor in the house' ! I would not have been aware of this book if not for the noises made by supporters and detractors in the blog-sphere. There are enough reviews in various blogs that I feel like I have read the whole book before I can hold one in my hand.
