And I know what you're thinking.

that it's impossible that Selina wouldn't have noticed.

A nanny living under her roof, heading towards full-term pregnancy.

I mean, here's a woman who's given birth to five children.

If anyone knows how to spot the signs of pregnancy, she does.

I asked Selina again.

Surely you noticed something.

Did she seem to be getting bigger?

Did you notice her getting bigger?

Because I knew nothing about it, I didn't sort of even analyse it.

No, you weren't looking for anything?

In the weeks afterwards, is there anything that you noticed that was her mood changing or her size changing?

A sense of anything about her?

And you know what?

I believe her.

I was there too, and I didn't notice.

While reporting this story, I learned something about my own mother, who's no longer around, a memory I'd never heard before, that my mum and Selina actually had a bit of a disagreement about it, with my mother insisting that it must have been Jennifer's baby, Selina adamant that it can't have been.

The fact is, back then, Selina had a sprawling family.

She was at capacity.

I can see how she might have missed things.
