A groove about a finger wide had been carved around the top of the stone, an inch or two from the edge. Time and weather had worn it smooth, almost glossy, but in one place the maker's handmade chisel had slipped, gouging a chunk out of the side of the groove and leaving a tiny, jagged overhang. A smear of something dark, almost black, clung to the underside.
"Helen here spotted it," Sophie said. The girl tech glanced up and gave me a shy proud smile. "We've swabbed, and it's blood-I'll let you know if it's human. I doubt it has anything to do with our body; her blood had dried by the time she was brought here, and anyway I'd bet this is years old. It could be animal, or it could be from some teenage scrap or whatever, but still, it's interesting."
I thought of the delicate hollow by Jamie's wrist bone, the brown back of Peter's neck bordered by white after a haircut. I could feel Cassie not looking at me. "I don't see how it could be connected," I said. I stood up-it was getting hard to balance on my heels without touching the table-and felt a quick head-rush.
Before we left the site I stood on the little ridge above the girl's body and turned full circle, imprinting an overview of the scene on my mind: trenches, houses, fields, access and angles and alignments. Along the estate wall, a thin rim of trees had been left untouched, presumably to shield the residents' aesthetic sensibilities from the uncompromisingly archaeological view. One had a broken piece of blue plastic rope heavily knotted around a high branch, a couple of feet dangling. It was frayed and mildewed and implied sinister Gothic history-lynch mobs, midnight suicides-but I knew what it was. It was the remnant of a tire swing.
Though I had come to think of Knocknaree as though it had happened to another and unknown person, some part of me had been here all along. While I doodled in Templemore or sprawled on Cassie's futon, that relentless child had never stopped spinning in crazy circles on a tire swing, scrambling over a wall after Peter's bright head, vanishing into the wood in a flash of brown legs and laughter.
There was a time when I believed, with the police and the media and my stunned parents, that I was the redeemed one, the boy borne safely home on the ebb of whatever freak tide carried Peter and Jamie away. Not any more. In ways too dark and crucial to be called metaphorical, I never left that wood.

I
don't tell people about the Knocknaree thing. I don't see why I should; it would only lead to endless salacious questioning about my nonexistent memories or to sympathetic and inaccurate speculation about the state of my psyche, and I have no desire to deal with either. My parents know, obviously, and Cassie, and a boarding-school friend of mine called Charlie-he's a merchant banker in London now; we still keep in touch, occasionally-and this girl Gemma whom I went out with for a while when I was about nineteen (we spent a lot of our time together getting much too drunk, plus she was the intense angsty type and I thought it would make me sound interesting); nobody else.When I went to boarding school I dropped the Adam and started using my middle name. I'm not sure whether this was my parents' idea or mine, but I think it was a good one. There are five pages of Ryans in the Dublin phone book alone, but Adam is not a particularly common name, and the publicity was overwhelming (even in England: I used to scan furtively through the newspapers I was supposed to be using to light prefects' fires, rip out anything relevant, memorize it later in a toilet cubicle before flushing it away). Sooner or later, someone would have made the connection. As it is, nobody is likely to link up Detective Rob and his English accent with little Adam Ryan from Knocknaree.
