Jess

I couldn't have fathomed the emotional cost of carrying a baby for nine months, feeling it flutter and kick, and then giving birth.

There can't be many lonelier situations.

I hadn't considered what those final moments must have felt like.

Dressing the baby, travelling to the verge, laying it down and walking away.

In 2010, after Jess visits The Verge and gets that tip-off from Jean about the local nannies, she tells me she gets in touch with the police.

One of the detectives agrees to meet her in a supermarket cafe.

He tells her everything he can remember.

The car sightings, the strange phone calls, door-to-door inquiries.

Much of the information I've seen in the police files.

He tells her about the frustration they all felt when they got nowhere.

This detective, he's one of the former police officers who didn't want to do an interview for the podcast.

But he does send me a note about one other thing he said to Jess.

It chimes with what Jess has already heard from Jean.

He's telling Jess that if she wants to know more about what happened that day, she should try and find this former nanny.

And he tells me he hands her something.

Jess tells me she's never seen this particular press cutting before.

It's new to her.

It's the interview which Terry Hunt did when he spoke to the young nanny who found Jess.

And it includes a photograph of her.

Armed with a name, Jess and her sister Laura go online.
