I could easily log in as Alicia, place the blame on Katy, but I don’t. She’s as duped as me. I feel a pang of sorrow. No doubt, right at the beginning, she believed that he loved her. She believed that he was trapped in a loveless marriage where they were ‘staying together for the kids’. She would have believed that he was just biding his time before he left.

Even when she had Jamie and Jack was living here (no doubt between ‘business trips’), she still believed it would all be fine. I can see it in her, wondering what the fuck is going on. Wondering how he can drift in and out of her life and make her feel so bad, yet still want him.

She’s like me. My science self kicks in and I wonder if there has been a study. I wonder if it’s only women who have children with philanderers that can’t get over them, that succumb to a certain brand of abuse.

I pick up a picture of Jamie. He’s bigger now. I look closer. He does have a look of Charlie. Around the mouth. I tear up as I realise that he’s Charlie and Laura’s half-brother. I try to think about the future. If all this works out the way I want it to, Jamie and Katy will be in my life for ever. It suddenly strikes me that this is the right thing. Charlie and Laura deserve to know their brother. Poor little Jamie, none of this is his fault. And it wouldn’t be too bad. Katy’s nice. She didn’t ask for this any more than I did.

But my work is done here – for now. I drive back to the hotel and pack my cases. It’s time to go home. None of these women are going to the police. All of them have more to lose than they have to gain. The only person who is complaining here is Jack. And that’s only because he’s finally been caught out.

I leave a note for Lee behind the bar – Nice meeting you, sorry I can’t make dinner. The barman discreetly hands me a piece of paper with a mobile phone number scribbled on it – Call me, Lee. I suddenly feel hot and my face glows red in the mirror opposite. I think it’s a warm glow.

I check out under the watchful gaze of the elderly couple who nudge each other and whisper. I glance at the TV on the wall as the receptionist calculates my bill. I catch a glimpse of #allgirlstogether on the This Morning show. A muted Holly Willoughby talks to two women, one who is labelled as ‘jilted’ and the other as ‘married to a cheater’.
