At an exclusive private school in Switzerland, mystery surrounds the identity of the beautiful raven-haired girl who arrives each morning in a motorcade fit for a head of state. She is said to be the daughter of a wealthy international businessman. In truth, her father is Khalid bin Mohammed, the much-maligned crown prince of Saudi Arabia. Once celebrated for his daring social and religious reforms, he is now reviled for his role in the murder of a dissident journalist. And when his only child is brutally kidnapped, he turns to the one man he can trust to find her before it is too late. What´s done cannot be undone. . . . Gabriel Allon, the legendary chief of Israeli intelligence, has spent most of his life fighting terrorists, including the murderous jihadists financed by Saudi Arabia. Prince Khalid--or KBM, as he is known--has pledged to finally break the bond between the Kingdom and radical Islam. For that reason alone, Gabriel regards him as a valuable, if flawed, partner. Together they will become unlikely allies in a deadly secret war for control of the Middle East. The life of a child, and the throne of Saudi Arabia, hang in the balance. Both men have made their share of enemies. And both have everything to lose.
