[George Smiley 04] • The Looking Glass War

An experienced agent is mysteriously killed on a freezing night near a foreign airport. Thus begins an intricate mission of military espionage that brings together three desperate men.

The zealot, the pawn, the string puller: each seeks a different kind of glory, each risks the thing he values most, each is caught up in a double-sided game that carries him from London to Berlin -- and from treachery, to betrayal, to cold-blooded murder.
