But as we start to piece all this together, you're right, what we see is that there's something else going on.

She's more than just a run-of-the-mill oddball and that something has happened in the past that wasn't right at all.

She can be a bit annoying as well.

Like she really does hurt people's feelings not realising because she has such limited personal and social contact.

We should say she lives alone.

She goes home on the weekend with two bottles of vodka and a Tesco pizza and absolutely demolishes herself.

So she's got some pretty extreme personal habits and sometimes can barely get to work because she's also a bit of a red wine fan.

Yeah, yeah, look, and, you know, this is kind of the really heartwarming thing.

There is somebody who is able to see that inside there is a different person than the one from the outside.

But Kate, I think this is really part of a growing genre of books that have a central character with a mental illness of some description.

And I'm trying to be careful because I know people want to read this and I don't want to give too much away.

And I'm not saying that characters with psychological conditions or personality disorders are new.

I mean, you know, Heathcliff,

Anna Karenina, Iago, all these disorders and personality types that we've seen.

But I think what we are seeing is that the disorder becomes the central concern of the book rather than a flaw that drives the narrative on.

It's a real trend, I think, that's on.

Rosie Project, Girl on the Train.

Girl with the Dragon Tattoo, many of them women actually, funnily enough.

But it raises some questions for me about what are we doing here?

Are we actually analysing people and diagnosing them in our amateurish way?
