102. The English Girl Daniel Silva 2013
Gabriel Allon is back in the saddle (Louis L'Amour reference), doing a favor for his old friend, Graham Seymour of MI-5. Not only is the British prime minister having an affair, but his mistress has been kidnapped. Allon finds her and solves the mystery of why she was taken, and by whom.
Decent, but I've read better Silvas.
