From Wondery, I'm Charlie Higson, and this is The Spy Who.

Now, as you may know, I am a novelist, actor, comedian, and overall spy enthusiast.

Although I have to say that my involvement with the world of spying is more on the fantasy level of James Bond

one last dive into the brilliant complex, but at times rather odd mind, of Klaus Fuchs.

Now, thanks to the film Oppenheimer, this key moment in history, the development of the

atomic bomb, has been brought back into the spotlight, giving us all a chance to remember

the great minds whose influence was as impactful in science as it was in politics.

Now, prior to this series, I didn't really know anything about food.

It's been fascinating to find out more about him.

And I'm really looking forward to speaking to our guest today, Frank Close,

author of Trinity, the treachery and pursuit of the most dangerous spy in history.

and together we're going to peel back the layers of the extraordinary life of a man

whose brilliance illuminated the atomic age,

but whose choices made him notorious.

of so many talents, author, celebrated scientist, OBE, and lecturer. I can only imagine the many things that intrigue you
