The British Embassy in Bonn is up in arms. Her Majesty's financially troubled government is seeking admission to Europe's Common Market just as anti-British factions are rising to power in Germany. Rioters are demanding reunification, and the last thing the Crown can afford is a scandal.
Then Leo Harting—an embassy nobody—goes missing with a case full of confidential files. London sends Alan Turner to control the damage, but he soon realizes that neither side really wants Leo found—alive.
Set against the threat of a German-Soviet alliance, John le Carré's A Small Town in Germany is a superb chronicle of Cold War paranoia and political compromise.
With an introduction by the author.John le Carré's short novel was first published in 1968 and in the "introduction" he wrote that he was not happy with the book. He meant it to be comedic but the German people were not too happy with his depiction of them. He revised some of what he wrote and he was half satisfied with the finished novelette.
