Sean shook his head and licked grains of sugar off his filthy fingers. "Nah, before that," he said, and I felt my heart rate start to pick up again. "I sort of forgot about it for a while, because I didn't need it-we were mattocking back that fucking drainage ditch-and I figured someone had, like, picked it up for me and forgot to give it back. That day you guys came for Mark, that was the first time I needed it, but everyone was going, 'No, I haven't seen it, uh-uh, wasn't me.'"
"It's identifiable, then? Anyone who saw it would know it was yours?"
"Totally. It's got my initials on the handle." He took another enormous bite of doughnut. "I burned them on ages ago," he said, in muffled tones, "this one time when it was lashing rain and we had to stay inside for, like, hours. I have this Swiss Army knife, see, and I heated up the corkscrew with my lighter-"
"At the time you accused Macker of taking it. Why?"
He shrugged. "I don't know, because he does dumb shit like that. Nobody was gonna
"And do you still think it was him?"
"Nah. I only realized after, Dr. Hunt locked the finds shed when we left, and Macker doesn't have a key-" Suddenly his eyes lit up. "Hey, was it the
"No," I said. "What day did you find the coin, can you remember?"
Sean looked disappointed, but he thought about it, staring into space and swinging his legs. "The corpse showed up on a Wednesday, right?" he said eventually. He had finished his doughnut; he balled up the plastic wrap, tossed it in the air and swatted it into the undergrowth. "OK, so it wasn't the day before that, because we were doing the fucking drainage ditch. The day before
I still think about this conversation with Sean. There is something oddly comforting in the memory, even though it carries its own inexorable undercurrent of grief. I suppose that day was, though it still comes hard to acknowledge this, the pinnacle of my career. I am not proud of a lot of the decisions I made in the course of Operation Vestal; but that morning, at least, in spite of everything that had come before and regardless of anything that came after, that morning I did everything right, as surely and easily as if I had never put a foot wrong in my life.
"Are you sure?" I asked.
"Yeah, I guess. Ask Dr. Hunt; he logged it in the finds book. Am I, like, a witness? Am I gonna have to testify in court?"
"Quite possibly," I said. Adrenaline had burned off the fatigue and my mind was speeding, throwing out permutations and possibilities like a kaleidoscope. "I'll let you know."
"All
"No," I said, "but I do need you to do something for me. I want you to go back to work and tell the others that we were talking about a stranger you saw hanging around a few days before the murder. I was asking you for a more detailed description. Can you pull that off?" No evidence and no backup: I didn't want to spook anyone, not yet.
"Course," Sean assured me, offended. "Undercover work. Excellent."
"Thanks," I said. "I'll get back to you later." He slid down from the hood and bounced off towards the others, rubbing the back of his head through the woolly hat. He still had sugar around the corners of his mouth.
I checked with Hunt, who went through his logbook and confirmed what Sean had said: he had found the coin on the Monday, a few hours before Katy died. "Wonderful find," Hunt told me, "wonderful. Took us quite a long time to…um…
"Who has a key to the finds shed?" I asked.
"Edward VI base penny, early 1550s," he said. "Oh…the finds shed? But why?"
"Yes, the finds shed. I've been told it's locked at night. Is that correct?"
"Yes, yes, every night. Mostly pottery, of course, but you never know."
"And who has a key?"
"Well, I do, of course," he said, pulling off his glasses and blinking fuzzily at me as he wiped them on his sweater. "And Mark and Damien-for the tours, you know. Just in case. People always like to see finds, don't they?"
"Yes," I said, "yes, I'm sure they do."
I went back out to the road and phoned Sam. One of the trees was dropping chestnuts, they were littered around my car, and I peeled the prickly casing off one of them and tossed it into the air while I waited for him to pick up: casual phone call, maybe setting up a date for the evening, if anyone was watching and worried; nothing important.
"O'Neill," Sam said.
"Sam, it's Rob," I said, catching the chestnut overhand. "I'm in Knocknaree, at the dig. I need you and Maddox and a few floaters down here as fast as you can, with a team from the Bureau-get Sophie Miller if you can. Make sure they bring a metal detector and someone who knows how to work it. I'll meet you at the entrance to the estate."
