As World War 2 winds to a close, Europe’s roads are clogged with twenty million exhausted refugees walking home. Among them are Jacob and Sarah, lonely Holocaust survivors who meet in Heidelberg. But Jacob is consumed with hatred and cannot rest until he has killed his brother’s murderer, a concentration camp guard nicknamed the Rat, also from Heidelberg.

     Jacob and Sarah, the only Jews in Heidelberg, fall in love. As Jacob waits for the Rat to come home, he is beset by doubt. If he fulfills his oath and kills him, he will undoubtedly be caught, and Jacob’s and Sarah’s new life will die too. Timeless dilemmas torture the young lovers and threaten to tear them apart.

     At the same time a secret hit team from the British army’s Jewish Brigade is assassinating former SS officers hiding out in Germany. What is more important, love or hate? The past or the future? Revenge or mercy? Ultimately it must be decided - who should be killed and who should live? Jacob’s Oath is both a painful love story and a riveting thriller with a very tricky ending indeed.
