Hitler unleashes a fatal haemorrhagic disease on Britain when he realises that he has lost the war in 1945. Some people die immediately, some later and those with an AB type blood group are survivors. Hoke, an American Pilot is a survivor and is pursued by dying "blackshirts" with the impossible idea that a transfusion will save them. Hoke meets several other survivors and the rest of the book is a run to survive and to kill the "blackshirts"

The characters are not very convincing. One hero, 2 women and a "reformed" German are the main cast. They are all running madly away from their pursuers as well as the bombs being dropped by a mad German flyer who does not know the war has ended. There are lots of bloody fights; gory descriptions of dead, desiccated bodies; as well as smoke, fire and collapsing buildings.

It's an entertaining book to read on a superficial level, but not one of his best.
