In the shadowy recesses of Whitehall and Washington an unholy alliance operates between the intelligence community and the secret arms trade. Jonathan Pine is ready to stand up and be counted in the fight against this ultimate heart of darkness. His mission takes him from the cliffs of west Cornwall, via northern Quebec and the Caribbean, to the jungles of post-Noriega Panama. His quarry is the worst man in the world.
The Department has faded since the war, effectively mothballed, without agents or resources. But now, with intelligence of a possible missile threat, it again has a mission. This is a chance to prove its influence to those at the Circus, like George Smiley, who think the Department's time has passed. The opportunity to reclaim former glory cannot be missed - even though it means putting men's lives at desperate risk on foreign soil. The Looking Glass War is a gripping story of the amorality of espionage - unflinching in its depiction of the men involved, who are as much full of vanity and fear as of selflessness and courage.
