Spy line. Len Deighton. 1990.

Berlin-Kreuzberg: winter 1987. Through the grey streets, the British Military Police are hunting for Bernard Samson - disgraced ex-field agent and perhaps the only man who both sides would be pleased to be rid of. But for Bernard, the city of his childhood holds innumerable hiding places for a spy on the run - from a seedy nightclub on Potsdamerstrasse to an SIS safe house in Charlottenberg..

But in this city of masks and secrets where there are many enemies - both seen and unseen - only one thing is certain: sooner or later Bernard’s wife Fiona must make her next move. Defector, traitor, KGB agent but still his wife, it is her startling reappearance that will set the scene for what promises to become the most thrilling endgame of them all.
