I waited. Holly said, ‘You’ve got older. You used to look like a student.’

‘And you used to look like a little kid who brought her doll to interviews. Clara, wasn’t it?’ That turned her head my way. ‘I’d say we’ve both got older, here.’

For the first time, she smiled. Little crunch of a grin, the same one I remembered. It had had something pathetic in it, back then, it had caught at me every time. It did again.

She said, ‘It’s nice to see you.’

When Holly was nine, ten, she was a witness in a murder case. The case wasn’t mine, but I was the one she’d talk to. I took her statement; I prepped her to testify at the trial. She didn’t want to do it, did it anyway. Maybe her da the detective made her. Maybe. Even when she was nine, I never fooled myself I had the measure of her.

‘Same here,’ I said.

A quick breath that lifted her shoulders, a nod – to herself, like something had clicked. She dumped her schoolbag on the floor. Hooked a thumb under her lapel, to point the crest at me. Said, ‘I go to Kilda’s now.’ And watched me.

Just nodding made me feel cheeky. St Kilda’s: the kind of school the likes of me aren’t supposed to have heard of. Never would have heard of, if it wasn’t for a dead young fella.

Girls’ secondary, private, leafy suburb. Nuns. A year back, two of the nuns went for an early stroll and found a boy lying in a grove of trees, in a back corner of the school grounds. At first they thought he was asleep, drunk maybe. Revved up to give him seven shades of shite, find out whose precious virtue he’d been corrupting. The full-on nun-voice thunder: Young man! But he didn’t move.

Christopher Harper, sixteen, from the boys’ school one road and two extra-high walls away. Sometime during the night, someone had bashed his head in.

Enough manpower to build an office block, enough overtime to pay off mortgages, enough paper to dam a river. A dodgy janitor, handyman, something: eliminated. A classmate who’d had a punch-up with the victim: eliminated. Local scary non-nationals seen being locally scary: eliminated.

Then nothing. No more suspects, no reason why Christopher was on St Kilda’s grounds. Then less overtime, and fewer men, and more nothing. You can’t say it, not with a kid for a victim, but the case was done. By this time, all that paper was in Murder’s basement. Sooner or later the brass would catch some hassle from the media and it would show up on our doorstep, addressed to the Last Chance Saloon.

Holly pulled her lapel straight again. ‘You know about Chris Harper,’ she said. ‘Right?’

‘Right,’ I said. ‘Were you at St Kilda’s back then?’

‘Yeah. I’ve been there since first year. I’m in fourth year now.’

And left it at that, making me work for every step. One wrong question and she’d be gone, I’d be thrown away: got too old, another useless adult who didn’t understand. I picked carefully.
