Vengeance is a 1984 book by George Jonas describing part of Mossad assassinations following the Munich massacre. It was re-released as Vengeance: The True Story of an Israeli Counter-Terrorist Team or Vengeance: Sword of Gideon in some later editions and countries. The main source of the book is also the main character, Yuval Aviv, known in the book as Avner. A Mossad officer, he is recruited to lead a small team into Europe to assassinate a number of suspected PLO and Black September militants. Each of the book's chapters deals with a separate stage of the mission, including the background to each assassination. It has inspired both a 1986 made for television movie called Sword of Gideon and the 2005 Steven Spielberg film Munich.
