who hadn't ever been to Cuba, but they were all US spies or diplomats or working for the US government in some way.

So we would talk to doctors and diplomats and so on.

But the story really changed for us and became what we really were fascinated by when we managed to get in touch with one particular spy who's known as Patient Zero.

And it was a long, tricky process.

But then I had this call with him.

It was just before Christmas one year.

And he's somewhere at the end of the line.

And I have this call with him.

And then I went to meet him in the UK where he happened to be coming over for Christmas.

And then I played Jennifer the tape when we got home.

And that's when we kind of really...

changed of view of the story right?

The shape of it.

in America on American interviews but he was born in the UK his parents are very English yes and I know lots of people do that their accent jumps around but it just made him feel like a more slippery character more interesting yeah because he's also so you know I can say as someone who spent a lot of time with him he's extremely charming just very gets on your level immediately you know this is someone who I have nothing in common with on the face I mean we're both like you know it's

And the CIA haven't knocked on your door yet.

Yeah, well, and he's such an improbable story as well.

So like that whole world of like, you know, the whatever, whichever country's intelligence operatives or whatever, it's just not only is it closed off, but you imagine that the people there are

very sort of buttoned up and tight-lipped and just sort of straight-laced and all the rest of it so they wouldn't necessarily they're not necessarily going to be great characters you know from the point of view of telling a story and contributors and all that they're not

necessarily going to be multi-dimensional, at least to you, when they're talking to you.

They're going to say exactly what they want to say and not reveal anything more.
