Still reeling from believing Finn is the masked killer, and almost killing him, I struggle to sleep – tossing and turning, jolting in and out of terrifying nightmares.

At DI Kate Beynon’s suggestion, Dad, Thomas and I are staying at a B & B in Inverness overnight. We’re to stay in the area until the search of the estate is complete. Rosamund and Neil are here too, though I haven’t seen them.

By 5 a.m. I’m wide awake, staring at the ceiling, trying to piece everything together.

And then it hits me.

There were two people there the night I was attacked. Yes, I heard two people. I’d called to the other for help. Had the second person been Finn?

I throw back the duvet and head into the shower. The piercing water on my flesh goes some way to making me feel human again, but I can’t rid myself of a dull headache, despite taking strong painkillers.

It’s 9 a.m. when Beynon rings my mobile. ‘I’d like you to come down to the station, Amelia,’ she says, and my stomach twists. ‘We need to take formal statements from everyone, and I’d like to begin with you.’

Dad drives me to the police station, and agrees to wait for me outside.

Once in the building, I head for reception, my skin prickling.

‘Amelia.’ It’s Beynon, appearing through a side door. ‘This way, please.’

Once sitting in the kind of room I’d only ever seen in crime dramas, Beynon and DS McKay opposite me, I say, ‘Do I need a solicitor? This is all a bit formal, isn’t it?’

‘It’s just a few questions, Amelia.’ She smiles. ‘You’re not under arrest. We just need a statement from you, that’s all.’

‘OK.’

‘And also to see if you’ve remembered anything new since we last spoke.’

‘Like what?’ Should I mention the second person?

‘Anything at all that might help us with our enquiries.’

‘Well, someone attacked me,’ I say.

She nods. I’ve told her this before.

‘And when I came round I saw a figure on the bench … wearing that awful mask. Finn.’

She nods. ‘We know that was Finn. His blood was all over the bench. But we know he wasn’t stabbed there. Someone moved him. Do you know anything about that?’

I shake my head. ‘I’ve no idea.’ At least that much is true.

‘If you know anything at all, Amelia, now would be a good time to say.’

There was something about Beynon that reminded me of a girl I knew at my senior school – a girl I never wanted to cross. And part of me wants to yell that it had all been a huge mistake. That I thought, when Finn crouched down in front of me, that he was the masked killer. I stabbed him.
