Judas Country is a first person narrative novel by English author Gavin Lyall, first published in 1975.
His dreams of having his own airplane and own charter company rapidly fading due to age and lack of money, but at least he is flying.
Not only did his employers go bankrupt, leaving him stranded and without pay, but his plane is impounded, he is mugged by mysterious assailants on a dark back street, and is trailed by an Israeli Mossad agent.
When he finds that the cases clearly marked “champagne” that he was supposed to be flying to Lebanon contain machine guns instead, he suspects that things are going to get a lot worse.
Judas Country was the last of Lyall's aviation themed novels, and was considered one of his best in his obituary in the Guardian in January 2003.
