A gripping World War II historical thriller set in the heart of Nazi Germany: the Reich built a science to decide who belonged. Then someone applied it to the Führer.

Berlin, under the Third Reich. An SD investigator named Fischer does the unthinkable: he runs Adolf Hitler's bloodline through the regime's own racial genealogy methods, and writes down what he finds. Within days, he is dead. So are the two men who read his report.

The secret file should have died with them. Instead, it lands in the hands of the two worst possible men. Wagner is a Kriminalpolizei detective whose entire life rests on a forged ancestry file. Muller is a military police captain who left his illusions at the front. What they hold is not a rumor. It is proof, by the Nazi regime's own standards, that the man at the top would not survive his own laws.

Everyone wants it. Reinhard Heydrich wants it for the power it gives him over the one man in Germany no one can touch. The Gestapo wants it erased, along with everyone who has read it. An SS general sees in it the blackmail of a lifetime, his ladder to the top of the Reich, and he will kill anyone standing between him and the report. And across the Channel, British intelligence wants it most of all: a weapon no army could match.

Shadows of Blood is a WWII conspiracy thriller and Berlin noir detective story, where Nazi security services and British intelligence race for the most dangerous document in the Third Reich, and two damaged, frightened men decide the truth is worth more than their lives.

Perfect for readers of World War II historical fiction, Nazi-era crime novels, and espionage thrillers in the tradition of Philip Kerr's Bernie Gunther series, Robert Harris's Fatherland, and Alan Furst.
