The story begins in London where a notebook of a killed al-Quaida suspect was found. An anti-terror organisation found pictures of the Vatican on it so they thought that there might be an attack on the pope. Due to the fact that in a few days will be a festival in the Vatican which will be visited by a lot of people especially catholics. Gabriel Allon, an operative, went there to check the situation. And in reality there was an attack to kill the pope but with a lot of luck Gabriel could safe him but however a lot of people died. In the next days Gabriel and his team revealed a lot of information about the attack and they also had a suspicion that Zizi al-Bakari, a billionaire, could be the big boss of this organisation. So they searched for a plan to find out if this suspicion would be right and what they are willing to plan next. Because of the knowledge that Zizi al-Bakari is interested in arts they offered him a valuable and unknown van Gogh. Zizi al-Bakari really liked the picture and-which was Gabriels plan- also the woman who showed him the portrait. Her name was Sarah Bancroft and the plan was about being the new art-branche boss of Zizi al-Bakari because his last had resigned. And the plan went right!
After some days Zizi al-Bakari invited her to his yacht to get to know her new colleagues. But just after some time Zizi al-Bakari and his team noticed that Sarah is a special agent so they sent her to Zurich asking who had sent her and after this to kill her. She was hit and treaten until she divulged who is her boss and gave other information about her job. But if you want to know whether they killed her and what else will happen in the end you have to read the book!
