Two months before Adolf Hitler's rise to power, a young woman is found half naked and near death in the woods outside Berlin. The only clue to her identity is a handbill advertising a lecture by Albert Einstein. Psychiatrist Martin Kirsch little knows this will be his last case. Searching for the truth about his celebrated patient, he finds professional fascination turning to love. His investigations lead him to Einstein's youngest son, Eduard, who is writing a book that will destroy his illustrious father and, in the process, change the world.
