“I’m not sure,” I said. It was, obviously, nice to know that I wasn’t losing my mind and imagining things; but now I was wondering whether I had actually remembered it at all or only seen it in the file, and which of those possibilities I liked less, and wishing I had just kept my mouth shut about the damn thing.

Cassie waited; in the evening light through the window her eyes looked huge, opaque and watchful. I knew she was giving me a chance to say, Fuck the hair clip, let’s forget we ever found it. Even now the temptation, tired and profitless though it may be, is to wonder what would have happened if I had.

But it was late, I had had a long day, I wanted to go home, and being handled with kid gloves—even by Cassie—has always made me itch; cutting short this whole line of inquiry seemed like so much more effort than simply leaving it to run its course. “Will you ring Sophie about the blood?”

I asked. In that dim room, it seemed all right to admit this much weakness at least.

“Sure,” said Cassie. “Later, though, OK? Let’s go talk to O’Kelly before he has an aneurysm. He texted me while you were in the basement; I didn’t think he even knew how to do that, did you?”

The office has only one chair apart from O’Kelly’s own, one of those faux-leather ergonomic things. The implication is that you shouldn’t take up too much of his space or time. I sat in the chair, and Cassie perched on a table behind me. O’Kelly gave her an irritated look. In the Woods 69

“Katharine Devlin, aged twelve,” I said.

“The ID’s definite, so?”

“Ninety-nine percent,” I said. “We’ll have one of the parents view the body when the morgue’s patched her up, but Katy Devlin was an identical twin, and the surviving twin looks exactly like our victim.”

“Leads, suspects?” he snapped. He had a sort of nice tie on, ready for his date, and he was wearing too much cologne; I couldn’t place it, but it smelled expensive. “I’m going to have to give a fucking press conference tomorrow. Tell me you’ve got something.”

“She was hit over the head and asphyxiated, probably raped,” Cassie said. The fluorescent lighting smudged gray under her eyes. She looked too tired and too young to be saying the words so calmly. “We won’t know anything definite till the post-mortem tomorrow morning.”
