At an exclusive private school in Switzerland, a beautiful girl arrives each morning and leaves each afternoon in a heavily protected motorcade fit for a head of state. Rumors fly as to who she is, but she is the daughter of Khalid bin Mohammed, the much-maligned crown prince of Saudi Arabia. When she is brutally kidnapped, he turns to the one man he can trust: Gabriel Allon, the legendary chief of Israeli intelligence. Together they become unlikely allies in a deadly secret war for control of the Middle East. -- adapted from jacket
