Por­trait of a Spy is Daniel Silva’s four­teenth espi­onage nov­el, the eleventh fea­tur­ing Gabriel Allon. Sil­va takes his read­ers on an emo­tion­al roller­coast­er ride as Allon emerges from reclu­sive retire­ment in Corn­wall and takes a break from restor­ing an icon­ic mas­ter­piece, drawn back to bat­tle glob­al ter­ror and reli­gious extrem­ism. Like all in the series, this sto­ry is well-researched and reflects crit­i­cal cur­rent world issues. Allon’s usu­al team of experts is reunit­ed includ­ing his men­tor, retired for­mer leader of Israeli intel­li­gence Ari Sham­ron. Their mis­sion, to track down and assas­si­nate the head of the net­works per­pe­trat­ing bomb­ings in mul­ti­ple Euro­pean cities, pro­ceeds with the high tech coop­er­a­tion of the US, the UK, and Israel. Once again Sil­va edu­cates and enter­tains his read­ers through an inge­nious thriller.
