The Reaper, Ted Allbeury

Anna Woltman kills in cold blood.  Without passion, without remorse. She is a woman charged with a mandate for revenge. Revenge for the shattering, senseless killing of her husband. Revenge for the nightmare atrocities suffered by millions in the war. One by one, across Europe and the United States, she stalks the men who still pay homage to Hilter. Men who must pay for their crimes with their lives. But her harvest of evil is abruptly halted when the secret Nazi organization known as ODESSA starts to fight back. Then prey turns menacing hawk for THE REAPER.
