What is the name of Daniel Silva's newest book?

Daniel Silva's newest book as of September 2015 is "The English Spy." The book is the 15th in the espionage series featuring Gabriel Allon, a member of Israeli intelligence.

In "The English Spy," Allon tracks down the killer of a beloved member of British royalty. In doing so, he faces a cabal that wants him dead.

Allon and his team, named Barak, the Hebrew word for thunder, call their employer the "Office," which is suggestive of the Israeli Mossad.
