Alec Christie is an agent of MI6.
Christie was assigned by his superiors to find out Majestic-12's plans. He discovered their operations involving the CincLock-VII security system, the Chameleon missiles and Komoron ships, and their desire to initiate a Cold War.
However Majestic-12 realised what he was doing, and added Christie to their liquidation list. Christie was captured by M-12's French allies and taken to the aircraft carrier Richelieu. There he was interogated fiercely, as the French had become worried that Jonathon Killian had his own plans that Christie may have also discovered.
