Orwell, Collected Essays. I bought a set of these years ago, but lost Volume 3, which I’ve just replaced. It still stands up very well after all these years, and has lots of fascinating stuff to dip into, such as a defence of English cooking.
Orwell is one of those writers, like Shakespeare, who lots of people have tried to claim, particularly during the Cold War. I was particularly interested therefore, to read his very level-headed assessment of the British Communist Party and his observation that its fluctuating membership was inversely proportional to the extent to which it embraced revolutionary politics and to which Russian and British foreign policy was in conflict. However sharp his phraseology at times, Orwell always stood against heresy-hunters, and he would certainly have recognised the kinship between McCarthyism and Stalinism.
