I leaned on a windowsill, sun warming my back through my jacket. Conway moved, back and forth across the front of the art room in an even long-legged stroll, hands in trouser pockets, while the girls filed in.

They settled, like birds. Holly’s lot by the windows, Joanne’s lot by the door. No one looking across the gap.

Slouched and fidgeted in their chairs; batted looks, eyebrow-lifts, whispers back and forth. They had thought we were done with them, had dumped us out of their minds. Some of them, anyway.

Conway said, over her shoulder to Houlihan, ‘You can wait outside. Thanks for your help.’

Houlihan opened and shut her mouth, made a small-animal noise, scuttled off. The girls had stopped whispering. Houlihan gone meant the fib of school protection gone; they were all ours.

They looked different, a blurry streak. Like the Secret Place, the strobe of it: I couldn’t see the separate girls any more, just all those crests on blazers, all those eyes. I felt outnumbered. Outside.

‘So,’ Conway said. ‘One of you lot lied to us today.’

They stilled.

‘At least one of you.’ She stopped moving. Pulled out the photo of the card, held it up. ‘Yesterday evening, one of you put up this card on the secrets board. Then sat here and gave us, “Oh God no, wasn’t me, never seen that before in my life.” That’s fact.’

Alison blinking like a tic. Joanne with her arms folded, bobbing a crossed foot, sliding a glance to Gemma that said OMG can’t believe we have to listen to this. Orla sucking her lips, trying to kill a nerves-giggle.

Holly’s lot were still. Not looking at each other. Their heads tilted inwards, like they were listening to each other, not to us. The lean of their shoulders into the centre, like they were magnetised, like it would take Superman to pull one of them away.

Just something.

Conway said, ‘I’m talking to you. The girl who put up this card. The girl who’s claiming to know who killed Chris Harper.’

A twitch around the room, a shiver.

Conway started moving again, photo balanced between her fingertips. ‘You think lying to us is the same as telling your teacher you left your homework on the bus, or telling your parents you didn’t sneak a drink at the disco. Wrong. It’s nothing like that. This isn’t small-time bullshit that’ll vanish when you leave school. This is real.’

All their eyes following Conway. Pulled by her; hungry.

She was their mystery. Not like me, not like guys, an alien mystery they were learning to barter and bargain with, a thing they knew to want but didn’t know why. Conway was theirs. She was a woman, grown: she knew things. How to wear what suited her, how to have sex right or how to turn it down, how to get her bills paid, how to balance through the wild world outside the school walls. The water where they were dipping their toes, she was over her head in it and swimming.
