This is one of Follett's early efforts and is very good....a British Jew who attended Oxford and then served in WWII before being captured and sent to a concentration camp is the main character. After the war he emigrates to Israel and becomes a topflight Mossad agent. His assignment in 1967 is to hijack a uranium shipment needed by Israel so that they can make their own nuclear weapons. This assignment brings him back into contact with several of his former student associates at Oxford prior to WWII.... one is now an Egyptian spy, another is a KGB agent and he also becomes involved with the daughter of one of his Oxford professors. It is a good read and hard to put down as the story nears its climax.
