Love his books. When I read The Spy Who Came in From The Cold , I came across an incident, a scene which almost exactly portrayed my FIL and the children (DH and his siblings) . Cornwell would have been considerably younger than FIL and very junior to him in “the office” but would certainly have known of him in Germany- the detail was too accurate to be mere coincidence.
My favourites were the 'Smiley' books but 'The Spy who came in from the Cold' was another. MawBe what an interesting anecdote! I am sorry he has died as I felt he was an intelligent writer who treated his readers as intelligent too.
