I hate Le Carre. How can anyone possibly write that well. Here is a book with all that depth and compassion, that doesn't preach at you, written with such deceptive simplicity. It is like Joan Sutherland singing - there is so much more below the surface. An old Foreign Office retainer, a common soldier and a man with brains and integrity. The book is about conscience and what to do about it, an abject lesson in right and wrong, developing around duplicity and truth. Such a worthwhile work. How could anyone score it other than 5/5
