And how did it go?

I mean, do you call and they don't obviously answer, hi, MI5?

It's around July 1990, and a young Annie Macron makes the trip to London for her interview.

She thinks she knows who she's meeting with, but she's still not 100% sure.

Nonetheless, she would arrive at an unassuming building, which was completely unmarked and also totally empty.

The British Secret Service is just that, secret.

In fact, for these organisations which are in every country around the world, secrecy is the biggest thing.

You could have passed someone from an intelligence agency this morning, stood behind them as they ordered their coffee, or looked over at them in the commute to the office.

That's the point.

They are just ordinary people doing an extraordinary job.

And one that Annie says you can't share with people, not even the ones around you.

I was going to say, it would be potentially quite isolating.

Because most people, when they have a bad day at work or anything like that, the first thing you want to do is whinge about it to a partner or your friends or whatever.

You know, you go out for drinks with people, everyone whinges about their work and, oh, God, the boss and blah, blah, blah.

But you can't.

So Annie has had her first interview, which she successfully gets through, and signs the Official Secrets Act, something that at the time of signing, I'm sure she would have never thought that she would eventually break.

After that, it's into the recruitment process.

And start work she does.

At the age of just 22 years old, Annie heads off to her first day as an intelligence officer for one of the world's most secretive government agencies.

Do you remember your very first day walking through those doors?
