There’s a sudden, intense flare of relief. Spinning on my heels, I wait for Anna to catch me up. ‘Oh I’m so glad.’ She flings an arm around my shoulders and for a moment we hug until the buckle of my bag digs into my belly and I pull away. What a shitty birthday this has turned out to be. If they knew what I’d done some people would say it’s kismet or karma and if this is the extent of it I’ve got off lightly. They’d be right.

‘Have you seen the others?’ I ask Anna.

‘Bo was with me for a bit. He and Dex got caught up in the crowd which was why they didn’t make it to the Old Stairs, then they got separated. No idea where Dex is now. He might have texted me back, but my phone’s croaked.’

‘I got nothing from him either.’

‘You think we can get out that way?’ She points into the murk. ‘Hope so.’

We pick our way down the pathway into the thick black air beside the outbuildings, me in front and Anna following on. As we’re approaching the alleyway between the buildings my eye is drawn to something moving in the shadows. A fox or a cat maybe? No, no, too big for that. Way, way too big.

I’ve stopped walking now and Anna is standing right behind me, breathing down my neck. Has she sensed it too? I turn to see her pointing not to the alley but to the railings on the far side of the outbuildings.

‘Anna?’

‘Thank God!’ She begins waving. ‘The boys have found us – look, over there.’ In the dim light two figures, their forms indistinct, are breaking from the crowd and appear to be making their way towards us.

‘Are you sure it’s them?’

‘Yes, I can tell by way they’re moving. That’s Dex in front and Bo’s just behind him.’

I watch them for a moment until a group of revellers passes by and the two men are lost from view. From the alley there comes a sudden cry. Spinning round I can now see, silhouetted against the dim light of a distant street lamp, a man and a woman. The man is standing and the woman is bent over with her hands pressed up against the wall, her head bowed, as if she’s struggling to stay upright. I glance at Anna but she’s still looking the other way. Has she seen this? I pull on her arm and she wheels towards me.
