London, 1952: A dense, choking smog engulfs the city, in this brilliantly imagined novel from the creator of the Matthew Shardlake series, set in an alternative Britain where Churchill has lost to the appeasers and Britain has surrendered to Nazi Germany after Dunkirk. As the long German war against Russia rages on in the east, the British people endure under authoritarian rule. Defiance, though, is growing. Winston Churchill's Resistance organization is increasingly a thorn in the government's side. And in a Birmingham mental hospital an incarcerated scientist, Frank Muncaster, may hold a secret that could change the balance of the world struggle. Civil servant David Fitzgerald, a spy for the Resistance, is given the mission to rescue his old friend Frank and get him out of the country. Soon David and a disparate group of activists become fugitives under the shroud of London's Great Smog, while David's Jewish wife Sarah finds herself in a world more terrifying than she ever could have imagined. - from Amzon
