John le Carre is probably the best fiction spy novelist on the planet. However, after Smileys People, he was left to his own political predilections, which were mostly leftist. His books became less interesting although still brilliantly written

Very exciting and relevant to today's situation. I thought that LaCarre did a great job of creating and forming the characters.

Good plot and delivery up to the end. Leaves you hanging as to what the book was really about. Thought perhaps a sequel was in the works, but do not see it.
