SPIES OF NO COUNTRY by MATTI FRIEDMAN
The story of four underground spies for the Arab section of the Haganah. They were native to the Arab world and could assume Arab identities. Working undercover in Beirut for two years, they operated under dangerous conditions collecting intelligence and sending messages back to Israel. Friedman considers what these spies, who were the nucleus of Mossad today, meant for the country they went incognito to help.
