The Mole (2000 - 2013)

The Mole has had five seasons of its Australian version, with the latter two taking place overseas in New Caledonia and New Zealand respectively. It is a reality television program with a twist. Not only does it not contain a public vote, but one of the 'contestents' on the show is trying to do everything in his or her power to prevent the others from winning the money on offer. It is up to the real contestents to work out who this person is, and the one who knows the least about their identity, as calculated through a computer quiz, is eliminated from the show. But who is this traitor? Who is the saboteur? Who is the mole?
