An elderly Jew, worried about the safety of his considerable wealth in thirties Germany, reinvests it elsewhere, moving to London in 1938. His gentile wife has died. Before leaving, he summons his Luftwaffe pilot grandson-only a quarter Jewish and carefully disguising it-to explain how the wealth can be recovered after the inevitable, European turmoil. In 1940, the grandson is shot down over England and lies dead, undiscovered, in a quiet private copse. Moving to the present, his remains are found by a university lecturer. Carefully recovered documents provide enough information to trace his two granddaughters in Germany, now in their sixties. Mark and his wife embark on an investigation that reveals fraudulent claims to the wealth, murders during the war, and, as the wrongdoers panic, in the present. Justice is done, the riches are restored to the entitled heirs, and the wicked either converted to the cause of justice or sacrificed their lives.
