Another masterful effort in the world of Gabriel Allon by Mr. Silva as Allon is once again drawn into the Israeli spy net when he witnesses a terror attack in London, and is then asked to shut down the same terror network. The catch is he needs the help of a woman whose father Allon killed some time ago when the father was a terrorist mastermind. This book gets extremely tense in parts, which Silva has once again demonstrated his gift for thriller writing. Can't wait for the new Silva novel which comes out next week....
