Synopsis:
Angela wells is a former agent who receives a hero's welcome upon her return to Thames House. But she's not there for a cordial visit. Instead, she demands to know what actually happened to Princess Diana, and what role MI-5 played in her death or else she will blow them all up. After the team diffuses the situation, they learn that Angela's true intention was to attack the Royal Family -- the whole bomb scare was meant as a distraction. When the team stops her new plan, they realize that the Royal Family was not her endgame: they are.
