The two detectives approach the bed like they’re approaching a caged animal. The woman perches on the end as the man takes the seat next to the bed. The nurse – Jen – hovers by the curtains, ready to pounce, as the doctor leaves.

‘While you’ve been treated, we’ve ascertained you have no distinguishing marks other than your blue highlights. No tattoos or scars,’ Detective King says, looking at his notepad. ‘Your dress and tights are from a high-street store, one of hundreds. And we have found no evidence of a bag in the area we’ve searched. There was a notepad in your pocket which we’ve had a look through. But again, no clue to your identity.’

‘We’ve checked CCTV in the area,’ Detective Matthews says, leaning forward. ‘You appeared from the trees, above the playground. Does that ring a bell?’

Lumin shakes her head. ‘No, I just remember being on the beach.’

‘Why not tell us about that then?’ the detective says gently.

Lumin puts her hand to her temples and massages them. ‘I heard voices, laughter.’ She looks back at Amber, face softening. ‘It was you and the other two ladies. I looked down at my feet, saw I didn’t have shoes on. Something was wrong. I was – I am – so confused.’ Her breath quickens.

‘Take your time,’ Amber says softly.

Lumin takes a quick gulp of water then nods. ‘I knew I needed help. So I started walking towards the voices. I was so confused. What had happened? Why wasn’t I wearing a coat, shoes? I tried to grapple with my thoughts and I started to realise … I didn’t know anything.’ She purses her lips, tears forming in her eyes, and looks down at her hands. ‘That’s when you came to me,’ she says to Amber. Amber takes her hand and squeezes it.

‘What memories do you have from before the beach?’ Detective Matthews asks.

‘Eating a gingerbread man. A house or a lodge. Curtains with red robins on them.’ She pauses. ‘A man with a beard. But they feel like distant memories.’

Amber reaches over for the picture she drew and hands it over. ‘She drew this.’

Detective King takes it and looks at it. ‘Could be anywhere,’ he says as Detective Matthews takes a photo with her phone.

‘Anything else?’ she asks.

‘A man with a beard calling out the name Lumin as he reaches towards me,’ Lumin replies. ‘I think that must be my name. It feels right. And – and I just remember crying and it being so hot and feeling scared. But that’s it, that’s all I can remember.’

Detective Matthews’ brow furrows. ‘Anything else?’

Lumin takes a deep, shuddery breath. ‘Nope.’
