‘Jamie?’ she calls out, but there’s hardly any wind. Her voice sounds loud and flat and she knows it hasn’t carried. Only the cries of the gulls come back.

She runs the other way, past the trampolines and the log flume, her eyes scanning the gaps. She’s panting now and she’s frightened.

Please God, let her find him.

She sets off past the coin kiosk and the Dolphin Derby – and then something catches her eye. Over by the carousel, there’s a telescope and she can see the shadow of a figure next to it. There’s a person sitting on the top of the railings, facing out to sea.

She approaches cautiously. She can see that it’s a man. He’s holding a phone to his ear beneath the hood of his cotton zip top. It’s him. It must be him.

‘Jamie?’

He turns as Tor approaches. He has straggly long hair, his face not fully stubbly. His eyes look hollowed out. He looks vaguely familiar.

She’s behind him now and his hips are so thin, he looks like a shadow, like he could just slip away and float like speck of soot.

She stops, scared he’ll fall. ‘Jamie,’ she repeats.

‘How do you know my name?’

‘Just come back over and I’ll explain,’ Tor says, calmly, although her heart is pounding. She holds out a hand to him, to come back to safety on the other side of the railings.

She can tell that she’s confused him. He looks at the phone and then at Tor, as if he can’t connect the two. And why would he?

‘Please, just come back this side. And we can talk,’ Tor says, but now, up close, she can see the terror in his face. He looks like Maddy, she thinks, seeing the resemblance and she just wants to grab him and hug him and keep him safe until she gets here. She wants him to know how much they’ve longed to find him and she smiles, still holding out her hand, but he shakes his head. He drops his phone, which falls by Tor’s feet.

‘It’s OK. It’s OK, I’ve got it.’ Tor bends down to retrieve the cheap phone, but at that moment, her attention is caught by Maddy who now arrives, running breathlessly up the gangplank with a security guard behind her.

‘Jamie!’ she screams. ‘Jamie!’

‘Mum?’

Tor sees Jamie register Maddy for a split second. He reaches out, but he loses his balance on the railing and, suddenly, he’s gone.

‘No!’ Maddy howls.

She runs over to Tor, who springs up and leans over the balustrade. Way below there’s a splash. Tor leans right over the edge, her eyes scanning the water in the dark, waiting for Jamie to come up.

‘Oh God,’ she says. ‘Oh God, no …’

Tor turns to Maddy, but she’s already scrambling up onto the balustrade.

‘Hold this,’ she says, shrugging off her jacket.

‘Maddy, wait,’ Tor urges, trying to restrain her, but Maddy brushes her off.
