I read these books a bit out of order. The first book is "Tinker, Tailor, Soldier, Spy", and the second Smiley book is "The Honorable Schoolboy" which I am reading now. TTSS has been made into a BBC series, as has "Smiley's People". This book was new for me because I'd only seen the BBC series. The pacing in the book is again so very excellent. You don't seem rushed at all, yet incredible things happen and have links to such a wide variety of other events.... yet the timing is like a Swiss watch! Just superb writing that creates exactly the right amount of tension. This George Smiley does not act like he did in TTSS. In this book, he is angry. All that he has worked for seems to be in the balance. Has his work mattered? Does it make a difference to anyone whether Karla is caught? George decides in this book that it does matter, and that the death of his friend, the General, is worth investigating. This is a much more forthright Smiley, a much more demanding and "in your face" Smiley. He does not sit back to wait, he acts and he is acting on his own. But the result of his connections of the many webs brings an amazing resolution at the end. You feel the sacrifice he has had to make, but you also feel that Smiley has indeed "left his mark", and left it well.
