The Trespasser (Dublin Murder Squad #6)

Shrug again. ‘He was there.’

I know Holly’s da, a bit. Frank Mackey, Undercover. You go at him straight, he’ll dodge and come in sideways; you go at him sideways, he’ll charge head down. I said, ‘You came here because there’s something you want me to know. I’m not going to play guessing games I can’t win. If you’re not sure you want to tell me, then go away and have a think till you are. If you’re sure now, then spit it out.’

Holly approved of that. Almost smiled again; nodded instead.

‘There’s this board,’ she said. ‘In school. A noticeboard. It’s on the top floor, across from the art room. It’s called the Secret Place. If you’ve got a secret, like if you hate your parents or you like a guy or whatever, you can put it on a card and stick it up there.’

No point asking why anyone would want to. Teenage girls: you’ll never understand. I’ve got sisters. I learned to just leave it.

‘Yesterday evening, me and my friends were up in the art room – we’re working on this project. I forgot my phone up there when we left, but I didn’t notice till lights-out, so I couldn’t get it then. I went up for it first thing this morning, before breakfast.’

Coming out way too pat; not a pause or a blink, not a stumble. Another girl, I’d’ve called bullshit. But Holly had practice, and she had her da; for all I knew, he took a statement every time she was late home.

‘I had a look at the board,’ Holly said. Bent to her schoolbag, flipped it open. ‘Just on my way past.’

And there it was: the hand hesitating above the green folder. The extra second when she kept her face turned down to the bag, away from me, ponytail tumbling to hide her. The nerves I’d been watching for. Not ice-cream-cool and smooth right through, after all.

Then she straightened and met my eyes again, blank-faced. Her hand came up, held out the green folder. Let go as soon as I touched it, so quick I almost let it fall.

‘This was on the board.’

The folder said ‘Holly Mackey, 4L, Social Awareness Studies’, scribbled over. Inside: clear plastic envelope. Inside that: a thumbtack, fallen down into one corner, and a piece of card.

I recognised the face faster than I’d recognised Holly’s. He had spent weeks on every front page and every TV screen, on every department bulletin.

This was a different shot. Caught turning over his shoulder against a blur of autumn-yellow leaves, mouth opening in a laugh. Good-looking. Glossy brown hair, brushed forward boyband-style to thick dark eyebrows that sloped down at the outsides, gave him a puppydog look. Clear skin, rosy cheeks; a few freckles along the cheekbones, not a lot. A jaw that would’ve turned out strong, if there’d been time. WideMain Body Indented grin that crinkled his eyes and nose. A little bit cocky, a little bit sweet. Young, everything that rises green in your mind when you hear the word young. Summer romance, baby brother’s hero, cannon-fodder.

Glued below his face, across his blue T-shirt: words cut out of a book, spaced wide like a ransom note. Neat edges, snipped close.

I know who killed him

Holly watching me, silent.

I turned the envelope over. Plain white card, the kind you can buy anywhere to print off your photos. No writing, nothing.

I said, ‘Did you touch it?’

Eyes to the ceiling. ‘Course not. I went into the art room and got that’ – the envelope – ‘and a balsa knife. I pulled out the tack with the knife, and I caught the card and the tack in the envelope.’

‘Well done. And then?’

‘I put it up my shirt till I got back to my room, and then I put it in the folder. Then I said I felt sick and went back to bed. After the nurse came round, I sneaked out and came here.’

I asked, ‘Why?’

Holly gave me an eyebrows-up stare. ‘Because I thought you guys might want to know. If you don’t care, then you can just throw it away, and I can get back to school before they find out I’m gone.’

‘I care. I’m only delighted you found this. I’m just wondering why you didn’t take it to one of your teachers, or your dad.’

A glance up at the wall clock, catching the video camera on the way. ‘Crap. That actually reminds me. The nurse comes round again at breaktime, and if I’m not there, they will freak out. Can you phone the school and say you’re my dad and I’m with you? Say my granddad’s dying, and when you rang to tell me, I did a runner without telling anyone because I didn’t want to get sent to the guidance counsellor to talk about my feelings.’

All worked out for me. ‘I’ll ring the school now. I’m not going to say I’m your dad, though.’ Exasperated explosion of sigh from Holly. ‘I’ll just say you had something you wanted to pass on to us, and you did the right thing. That should keep you out of hassle. Yeah?’

‘Whatever. Can you at least tell them I’m not allowed to talk about it? So they won’t bug me?’

‘No problem.’ Chris Harper still laughing at me, enough energy running in the turn of those shoulders to power half Dublin. I slid him back in the folder, closed it over. ‘Did you tell anyone about this? Your best friend, maybe? It’s grand if you did; I just need to know.’

A shadow sliding down the curve of Holly’s cheekbone, turning her mouth older, less simple. Layering something under her voice. ‘No. I didn’t tell anyone.’

‘OK. I’m going to make this call, and then I’ll take your statement. Do you want one of your parents to sit in?’

That brought her back. ‘Oh, Jesus, no. Does someone have to sit in? Can’t you just do it?’

‘What age are you?’

She thought about lying. Decided against it. ‘Sixteen.’

‘We need an appropriate adult. Stop me intimidating you.’

‘You don’t intimidate me.’

No shit. ‘I know, yeah. Still. You hang on here, make yourself a cup of tea if you fancy one. I’ll be back in two minutes.’

Holly thumped down on the sofa. Coiled into a twist: legs curled under, arms wrapped round. Pulled the end of her ponytail round to the front and started biting it. The building was boiling as per usual, but she looked cold. She didn’t watch me leave.

Sex Crime, two floors down, keep a social worker on call. I got her in, took Holly’s statement. Asked your woman, in the corridor afterwards, would she drive Holly back to St Kilda’s – Holly gave me the daggers for that. I said, ‘This way your school knows for definite you were actually with us; you didn’t just get a boyfriend to ring in. Save you hassle.’ Her look said I didn’t fool anyone.

She didn’t ask me what next, what we were going to do about that card. She knew better. She just said, ‘See you soon.’

‘Thanks for coming in. You did the right thing.’

Holly didn’t answer that. Just gave me the edge of a smile and a little wave, half sarcastic, half not.

I was watching that straight back move away down the corridor, social worker duckfooting along beside her trying for a chat, when I copped: she’d never answered my question. Swerved out of the way, neat as a rollerblader, and kept right on moving.

‘Holly.’
