Knowles and Mahmood were killed in the blast and Montague is in intensive care. Mike Travis, her junior Minister of State, is appointed Acting Home Secretary and transfers responsibility for investigating the bombings back to Counter Terrorism Command.
It seemed obvious to me from the video that the bomb didn’t come from the briefcase, but the stage. This is confirmed, but subsequent episodes will not reveal just how the bomb is planted.
Budd falls under suspicion for not spotting the bomb when he spoke to Mahmood.
The next day, the PM announces that Montague is dead.
Budd attempts suicide, but fails because someone has replaced the bullets in his hidden pistol with blanks.
It looks like the effects of trauma are starting to take effect.
