“House of Spies” by Daniel Silva – Destroyer of the West

Daniel Silva has introduced us seventeen books ago to Gabriel Allon, legendary spy (now chief of Israeli Intelligence) and art restorer on the sly. His adventures have taken him around the entire world as he stopped one terrorist threat after another, and in his latest outing titled "House of Spies" , he sets on the trail of a very dangerous man who left London's West End in ruins more or less. In order to get to him, Allon makes an uneasy alliance with an enormously wealthy drug dealer who conducts business with the wanted man.
