Hope that is sufficient
here you are -
Section D learn from the Venezuelan secret service that the visiting Venezuelan president is being targeted by CIA hit-man Annibal Rodriguez. If MI5 prevent the assassination, the Venezuelans will provide intelligence they have regarding an al-Qaeda attack on a British school.
Zaf's tortured corpse is found (so yes he is dead!) and Bob Hogan identifies a group called the Red-backs, who torture spies to extract intelligence. When Jo's snatched by them, Adam asks Hogan to make contact and offer money for her safe return. Hogan sets up the exchange but reveals himself to be a Red-back and Adam's captured too.
Ben apprehends Rodriguez before he can kill the Venezuelan president, but the CIA, who commissioned the assassination, are incensed.
Harry sends a team to find Hogan, but the CIA reach him first. Hogan's willing to give up Jo and Adam, but the CIA won't let him talk to MI5 unless they get Rodriguez back. But if Rodriguez is returned to the Americans, the Venezuelans won't provide Harry with information on the school attack.
Harry's solution is to tell the CIA that Rodriguez is dead, but he does a deal to share the intelligence about the al-Qaeda attack, agreeing that the US can have the terrorists.
Jo tells Adam she would rather die than be tortured - she asks him to kill her himself.
As the special ops team rush to take out the Red-backs, Adam's holding Jo in his arms... are they too late?
So Zaf was dead.
Looks like Adam killed Jo (she asked him to to avoid rape and torture.)
Grim stff.
