‘Wow!’ she perks up, having spent a few minutes studying the tickets, ‘I really liked the first film! Girls’ night out! Thanks, Erika.’ She starts reeling off her clothing options; the red, sparkly dress is disregarded as it is far too low cut, the purple dress she wore to the Christmas party last year has shrunk in the wash and now reveals most of her bum-cheeks, so that’s no good either. Just as she is proposing a girly shopping trip, she pauses when she registers the expression on my face.

‘This isn’t for me, is it?’ she asks, to which I scrunch up my nose and shake my head, all the while grovelling apologies. ‘Who the fuck would you rather take than me?’

I realise at this point that I haven’t told her about what happened last time we were out together. About Tom. For the next few minutes, I divulge every sordid detail about my night with Tom, knowing this will win her round. Her mood changes as she asks question after question, and once she is content that no detail has been spared, she confirms that taking Tom sounds like a good idea.

I pocket the tickets and the conversation moves on to more mundane subjects; her new hair which she hates because the stylist didn’t layer it properly and her sexy weekend away with her husband. We each have one more drink and call it a night.

I spin the hot water tap with my toe and let the water run, topping up the bath I’ve been sitting in for just under thirty minutes. I glance at my hands and realise they’ve gone wrinkly, immediately thinking of Macauley Culkin in the bath in Home Alone, feeling super creepy in the process. I blow out the candle that has been illuminating the room and grab a towel from the radiator, pulling it around me, enjoying the continued warmth.

Once I’m mostly dry, I lie down on the bed and grab my laptop from the top drawer of the bedside table. A beeping noise signals a low battery, so I retrieve the charger and plug it into the wall before logging in.

I access my work files and load up the CCTV footage from the bar on the night Anna was killed. I watch again as Anna and her friend enter the bar, the action playing out in the exact same way as on the first viewing. Except this time, my attention is not trained on Anna, but on the friend. She is a little shorter than Anna, dressed in a plunging, stripy playsuit with her dark hair pulled into a high ponytail. As Anna is accosted by fans, her friend stands to the side, hand on hip with more than a hint of jealousy on her face.

Anna reconvenes with her friend and they go to the bar with a small crowd following them, smartphones in hand trying to get a picture of the celebrity in their midst. Once they’ve been served, they shimmy to the dancefloor where they remain for the duration of a few songs until Anna glances up and finds Ed and Reuben at the back of the bar. She leans close to her friend and says something in her ear before leaving the dancefloor.
