- The Mole couldn't have been anyone BUT Nigel. The carrier pigeon betraying the plan to the government was found literally just after he announced the breakout plan. He's the only one who would have known it. You'll notice that he is visibly nervous after the pigeon is discovered.

It's also supposed to take place in the same year as the film was released.
