With a passion for solving crime, fueled by the unsolved murder of her father’s death at the hands of a mass murderer days before she was born, law student Fiona Reid sets about the task of catching a mass murderer.
The story of Michael Berg, a German lawyer who, as a teenager in the late 1950s, had an affair with an older woman, Hanna, who then disappeared only to resurface years later as one of the defendants in a war crimes trial stemming from her actions as a concentration camp guard late in the war. He alone realizes that Hanna is illiterate and may be concealing that fact at the expense of her freedom.
