I nearly laugh, because lucky is not what I have been. I should never have had to go through this, and I still think it’s Jack’s fault. He can be as nice as he wants at the meeting – I know it’s only because there’s something in it for him. But I’ll take it where I can because if I don’t go through with this today then he could get the children full-time and I’ll be back to square one.

Eileen takes me to her office and we discuss what will happen with the big psychopath project. I’ve been given the lead and it’s all down to me to plan it out. It’s what I’ve wanted for a long time. I lean forward and indicate that I’m taking Eileen into my confidence.

‘Of course, with all that’s happened over the past week, things have changed at home.’ She’s leaning in too, eager for the gossip. ‘I’ve got a meeting with social services this afternoon. I might be getting the children back part-time.’

She clasps her hands in front of her and offers me a doughnut. I glimpse a #teamCaro rubber band around her arm.

‘Oh Caroline, that’s wonderful.’

‘Yes, it really is. So I might need a couple of days to sort things out, then everything will be back to normal.’

She looks pleased. The clock ticks on and I need to get to town.

‘Great. I’ll start it all on Monday, then. I honestly can’t wait.’

I can’t. I’ve got the perfect subject in mind to model my thinking on.

I’m out of the university and back in my car. I sit outside for a minute, still fuming about DS Percy. I get out my phone and call her, but it goes to answerphone. I wait a couple of minutes to see if she rings me back but she doesn’t.

Why was she here? She’s got what she wants. She’s got Peter Daubney’s thief and Emma is safe and hasn’t spilled the beans. If she had, I’d have been arrested by now. I’ve deleted the Facebook profiles so Jack will have to drop the charges. I expect she was looking for evidence against my stalker, but something deep inside tells me that isn’t the case. She knows it’s him, she told me. She’s got evidence.
