The Defector by Daniel Silva

The last Silva book that I read was not very good and I noted that I'd give him a change to redeem himself before I quit reading his works.  Well, he has done so in "The Defector."  Gabriel Allon is back in fine form to lead the action through Moscow, Italy and London in an attempt to find a former Russian spy who once saved his life.  The pace is fast and tense.  Good read.
