It is a great pity that one can not get a good book about Russia or China in Britain. One I read a couple of years ago about Chairman Mao was simply a total rubbishing job, and one about Kruschev who is an interesting man, by Willam Taubman, seemed to be written as a primer for schoolchildren whose title ought to b 'Why all Rusians are evil and bad'. It does not even mention Krushchev hammering his shoe at the UN after the Gary Powers incident. I suppose the publisher was scared that we might like K. for that.
Actually the most unreadable non fiction book ever written is The Seven Pillars Of Wisdom. Don't try it, you'll die.
