King contacts Harry, and tells him that he has planted a bomb in London; the entire team must approach the car containing the bomb or else he will detonate it, killing nearby civilians. The team deduces that well placed officials must be involved in order to get King into the country. Connie confronts Hogan and realises that it was not the Americans, leaving Whitehall as the prime suspect.
With their wits, and a little help from Hogan, the team find King stop him. Harry confronts the Home Secretary regarding the plot and discovers that it was part of a peace deal with Bakhshi. The UK would sell to Tehran a nuclear reactor that uses fuel that cannot be made into weapons.
