This is the first book by Mr. Le Carre that I have read--I seen a couple movies and TV adaptations. It was an interesting book and an interesting time to have it fall into my reading lap as Russia had just invaded the UKraine and the rest of the world speculates on WW3. You like to think that a lot of fiction is just that---but some like this book are just fictionilized versions of true things. As GOT fans are wont to say "The night is dark and full of terrors." And a sad truth is that the war on terror is often fought with the weapons of terror--no good men or bad men just gray men.
