afterwordOn a warm July evening in 1985, a middle-aged man stood on the pavement of a busy avenue in the heart of Moscow, holding a plastic carrier bag. In his grey suit and tie, he looked like any other Soviet citizen. The bag alone was mildly conspicuous, printed with the red logo of Safeway, the British supermarket.The man was a spy. A senior KGB officer, for more than a decade he had supplied his British spymasters with a stream of priceless secrets from deep within the Soviet intelligence machine. No spy had done more to damage the KGB.
