TWO ANGELS OF DEATH. After a gap of ten years, a female serial killer - the Angel of St Pauli - again makes the headlines when an English pop star is found in Hamburg's red-light district, dying of the most savage knife wounds. Jan Fabel is called in to investigate. Links emerge with a series of apparently unrelated events. A journalist murdered in Norway. The death of a Serbian gangster. And a long-forgotten project by East Germany's Stasi conceived at the height of the Cold War, involving a highly-trained group of female assassins, known by the codename Valkyrie. Fabel's hunt for the truth will bring him up against the most terrifyingly efficient professional killer. The ultimate avenging angel.
