Gabriel Allon is the main protagonist in Daniel Silva's thriller and espionage series that focuses on Israeli intelligence. The main characters refer to their employer as 'the Office', although it is not specified that it is Mossad (known internally in the Israeli intelligence community as HaMisrad [עברית: המשרד], literally 'the Office'). Allon's career began in 1972 when he, Eli Lavon and several others were plucked from civilian life by Ari Shamron to participate in Operation Wrath of God, an act of vengeance to hunt down and eliminate those responsible for killing the Israeli athletes in Munich. Wrath of God is referenced in the books throughout the course of his life. Source: Wikipedia (en)
