The Fearmonger

Two would-be assassins: One in a mental ward, another on the run. Their intended vitcims stirring up the mobs. Terrorists are planning a strike of their own. A talk-radio host's loving every minute of it. A Whitehall insider whispers about a mysterious UN operative with a hidden agenda.

Everyone's got someone they want you to be afraid of. It'll only take a little push for the situation to erupt - and something is doing the pushing. But you can trust Doctor to put things right, can't you?
