The New Girl by Daniel Silva

The "new girl" in the title of the latest Gabriel Allon novel is the daughter of  the future leader of Saudi Arabia, Khalid bin Mohammed (or KBM as he's popularly known). When she is kidnapped from her exclusive Swiss school, Khalid  is desperate enough to call Gabriel for help. Soon the whole balance of power in the Middle East is at risk.

In this novel we see the return of American art expert/former CIA spy, Sarah Bancroft and Russian mole/former MI6 bigwig, Rebecca Manning. All in all, it's quite the page-turner with eerie similarities to real events.
