While Silva's last book delved into a smuggler plot at the Vatican, Allon shifts gears in his 13th book in his Gabriel Allon series "The English Girl" http://www.amazon.com/The-English-Girl-Novel-Gabriel/dp/0062073168/ref=sr_1_1?ie=UTF8&qid=1380077202&sr=8-1&keywords=The+english+girl and tells the story about the kidnapping of Madeleine Hart, who is the mistress of the English Prime Minister. The girl is being held for ransom. The Prime Minister does not want to reveal the affair so he wants to pay, but is willing to let Gabriel Allon try to find the girl.
Allon has 7 days to find the girl.
Although Allon gets close to freeing Hart, the time period elapses and the minister agrees to pay, but the kidnappers somehow know Allon is involved and want him to deliver the ransom. After the drop, Allon is told where to get Hart, but is ambushed by a shocking explosion.
Allon now takes it upon himself to figure out what happened and wants to get revenge on the kidnappers.
Of course, Israel is reluctant to commit its resources to Allon's plan, but Allon's old boss will persuade the Israeli leaders to do so, if Allon finally will agree to become the new head of Mossad, a position that he has constantly refused to take.
After assembling the familiar cast of characters from the prior books, plus a new addition, Allon soon learns some interesting facts about the kidnappers and their country of origin, and must somehow defeat them. There are double agents and some surprising twists and turns. Its a quick read.
Silva's ability to switch from a plot involving Hezbollah and the Vatican in the prior book to completely different more cold war plot and new world economics is a mark of his singular talent.
This volume has all of the familiar Allon plot elements, but it all works.
