An astonishing, unforgettable novel: a thrilling Second World War assassination plot told with rare literary brilliance.

Two men have been enlisted to kill the head of the Gestapo. This is Operation Anthropoid, Prague, 1942: two Czechoslovakian parachutists sent on a daring mission by London to assassinate Reinhard Heydrich - chief of the Nazi secret services, 'the hangman of Prague', 'the blond beast', 'the most dangerous man in the Third Reich'. His boss is Heinrich Himmler but everyone in the SS says 'Himmler's brain is called Heydrich', which in German spells HHhH.

HHhH is a panorama of the Third Reich told through the life of one outstandingly brutal man, a story of unbearable heroism and loyalty, revenge and betrayal. It is a moving and shattering work of fiction.
