Tinker Tailor Soldier Spy is out on DVD on Monday. It's hard to put into words just how beautiful Tomas Alfredson's adaptation of John le Carré's novel is. The ugly wallpaper. The massive glasses. Gary Oldman's face.

So rather than try and describe that atmosphere of distrust and period decay, we've distilled the essence of being George Smiley into an elegant, stylish and sophisticated Flash game (that's the first time you'll hear those words together).

There's a mole at the top of The Circus. Can you find the traitor amid the thesps? Can you separate the sneaky beast from the double-crossers? Can you bash its face in with a metaphorical shovel?

This is Tinker Tailor Whack-a-Mole.
