Book 15 in Daniel Silva‘s Gabriel Allon series was another hit. There are a lot of references to events in previous books, so it‘s probably best to start the series from the beginning. This installment was packed with action and intrigue. I‘m glad we still have Shamron, even though he plays a brief role here, and it‘s always great to see old friends, like Julian Isherwood. I love this series. Silva is a master of his craft.
