She is an iconic member of the British Royal Family, beloved for her beauty and charitable works, resented by her former husband and his mother, the Queen of England. When a bomb explodes aboard her holiday yacht, however, British intelligence turns to one man to track down her killer: legendary spy and assassin Gabriel Allon. Gabriel Allon is soon on the tail of Eamon Quinn, a master bomb maker and mercenary of death who sells his services to the highest bidder. Why would Quinn kill a member of the royal family, however, and draw unwanted attention to himself? Allon seeks the aid of Christopher Keller, a British commando turned professional assassin who knows Quinn's murderous handiwork all too well. The two are up against a cabal of evil with an intricate plan for revenge.
This is the best Gabriel Allon book in several outings. His previous several books seemed somewhat over the top.
With Chiara, the wife of Allon, having given birth to twins, and Allon, due to take over as chief of the Office, one wonders where this series is going next.
