A Small Town in Germany
I found this gem, a 1970 first print run paperback, in the Odd Book in Wolfville Nova Scotia, while hunting for a coffee.
A Small Town in Germany is a little unusual for Le Carre, because it focuses on British Foreign Office staff working at the Embassy in Bonn rather than 'the Circus' (MI6) and also doesn't feature his most famous creation, George Smiley. The Constant Gardener and a Delicate Truth are the other Le Carre books where the Foreign Office is central.
Apparently Le Carre didn't like the book very much when he finally finished it. When he reread it towards the end of his career he admitted it was better that he had recalled. No spoilers please, I haven't finished it yet!
