There's a mole. Right at the top of the circus. He's been there for years.
How do you find an enemy. Who is hidden. Right before your eyes?
I need you to do something. You have to assume they're watching. Things aren't always what they seem. Moscow has planted the mole. It is one of five men. He killed our man in Istanbul. Now is the time.
Based on John Le Carré's best-selling novel.
It has become so ugly. We're not so very different you and I. We both spent our lives looking for the weaknesses in one another.
Tinker Tailor Soldier Spy.
