I logged onto HOLMES and had a quick rummage – and there it was. An action for someone to go through all the witness statements and see if there was a reference to the girls going out at night and dancing – with or without clothing. There wasn’t any result.

The child psychologist rode back with Hannah and Joanne to their house and noted that Hannah had explained that they had different kinds of dances for different occasions – when Joanne exploded. The child psychologist actually wrote that in their notes – at that point the mother exploded! That would have been a fearsome sight even in the spacious back seat of a traffic BMW. The child psychologist felt that the outburst might have been a good thing, because Hannah knew her mother was upset and would have been tense and inhibited in the expectation of parental disfavour.

But she was shocked by the swearing, some of which she had to look up on the internet.

Hannah, now presumably disinhibited, got her dinner, then some telly and then magnanimously agreed to talk to the child psychologist again. Albeit on the condition that she be allowed to watch the Disney Channel at the same time.

When asked what had happened after she and Nicole had sneaked out of their houses and met up, Hannah explained, in a distracted fashion, that they’d taken secret paths up to the moor where they’d met a beautiful woman riding a unicorn. The child psychologist worried at the last statement – did Hannah mean a woman on a horse?

No she meant a lady riding a unicorn – side saddle!

Was this ‘unicorn’ perhaps Nicole’s invisible friend Princess Luna?

Hannah was not impressed – Princess Luna is a completely different unicorn.

Did this unicorn have a name?

The lady never said.

Did the lady have a name?

Yes, the lady’s name was Lady.

The child psychologist then sits through an episode of Phineas and Ferb before, quite spontaneously, Hannah explains that they walked for miles and miles and miles, then they went downhill and through a cave by a river and then up a hill where they had a sleep.

In the open?

No, Hannah thought there had been tents, old-fashioned tents made of skins or possibly rainbows. And there had been kebabs but she didn’t think they were good kebabs because she’d felt sick afterwards. Then they’d woken up and hadn’t had to have a wash or clean their teeth or anything.

I made a note to check the medical report and see whether their teeth had been neglected or not.

The next morning they had walked down a hill for a very long way and she’d been really tired and it was getting dark when they went up a hill and into a castle.

What kind of castle?

A castle castle.

Could she remember what colour it was?

Pink and blue and orange.
