”SS-GB” by Len Deighton (published by Penguin Books)
If Nazi jackboots had tramped down Whitehall
SS is an abbreviation of Schutzstaffel (Protection Squadron), the black-uniformed elite corps that was one of the most feared organisations in Nazi Germany. GB is short for Great Britain. ”SS-GB” is Len Deighton’s 1978 novel imagining what might have happened if Germany had fought its way across the Channel and subjugated the island in World War II.
