We ride round and round on the tram, getting off to buy a new ticket every now and again. I don’t want to get into trouble. I wonder what Emma must really think of all this. How she must feel when she sees Jack with these women? Knowing Emma and knowing him, she’ll think that she has changed him. She’ll believe that she’s different, that she’s the one who has made him settle down.

We all think that. No doubt everyone in the journal thought that until the next one came along. I snigger and shake my head because for all his protestations that I didn’t, I know Jack. He was trying too hard. He still is. Making himself believe that Emma was the one. That he didn’t want to blow it with her. That he would do anything. Maybe he really does believe that himself, that each woman is the one – until he gets bored and finds an excuse why she’s not.

When the tram reaches full circle, we get off at the park and sit on a bench at the station. I deactivate made-up Monica’s profile and give the laptop to Paula, who changes the passwords to something I don’t know. I switch off the laptop; it’s nearly out of battery anyway. I won’t be using it again.

When I get home I go to put everything in the hole, forgetting that it’s a smouldering pit now. Paula takes it all from me and I have to trust her. I have to trust someone again. I wonder what Emma will have told the police and how she has persuaded Allan Parrott not to tell them it was her behind the photos. I conclude that it’s none of my business and I’ve got enough to think about.

I must have fallen asleep on the settee because when I wake up it’s a dull Monday morning and Paula’s gone, back to Patti. I make coffee and my phone rings. It’s Katy.

‘Hi. You OK?’

I feel a bit bad that I need to convince her to let Jack see Jamie, but I’m glad she’s phoned.

‘Yeah. How are you? Feeling any better?’

There’s a pause. She’s crying.

‘Not really. Did you see that they found that Emma? She was locked in a shed or something. Do you think it was him?’

‘No. Wasn’t it a woman?’ I make it up as I go along as usual. Careful, Caroline. Not too many details. ‘Look, I’ll be over to get my car and my stuff in a minute. Now they’ve got that guy, I might as well stay at home. But thanks for the room.’

She brightens.

‘Yes. Come over.’

Twenty minutes later I’m sitting in her front room with a cup of tea.

‘So what did the police want?’
