4 1/2 star read. The 16th book in the Gabriel Allon spy series was a fast paced, ripped from the front page of the newspaper kind of read and I thought it was terrific. Allon is up against a new adversary., the man they call Saladin, the master planner of atrocities who has planned and executed a massive bomb attack in Paris. ISIS is responsible but Saladin planned it all. And he is planning more attacks. To try to stop him, a new recruit is sent to infiltrate his network, a young woman, a Doctor. But Saladin is a worthy adversary for Gabriel and despite the new recruit's best skills, will she be trusted enough to help Gabriel and his team avert a major catastrophe? I thought this was one of the strongest books in the series and very prescient on what is happening in the real world. Another great book from the master.
