Spooks, Series 4

Zaf:
Okay, I'm ready.

Adam:
Now don't forget, we're only playing "What if?"

Zaf:
You mean what if Harry organized the assassination of Princess Diana? I think he could have.

Ruth:
You don't mean that.

Zaf:
Don't I?

Ruth:
It's the conspiracy theories, they suck you in.

Zaf:
Yeah, they do. Some say it was caused by satanists because Diana's mercedes crashed into the 13th pillar in the tunnel. Then there's the theory that limo was stolen a month before by the Israeli secret service. The steering was modified so it could be controlled by a remote radio signal.

Ruth:
Now Mossad did it?

Zaf:
No. MI-5 and MI-6 did it in a joint operation. And I'll show you how. The British Embassy in Paris denied ever knowing that Diana had arrived in Paris. But they did. And the night before she arrived at the Ritz, two very high-ranking MI-6 officers arrived at the embassy.
