"Not necessarily in the wood," Cassie said. "On the dig, or on the road, maybe? Was anyone out there after, say, half past eleven?"
"Hang on, now," Mark said suddenly, almost reluctantly. "Out on the site. There was someone."
Neither Cassie nor I moved, but I felt the electric spark of alertness shoot between us. We had been about ready to give up on Mark, check his alibi and put him on a question-mark list and send him back to his mattock, at least for now-in the urgent first days of an investigation, you have no time to waste on any but the most crucial things-but he had our full attention again.
"Could you give us a description?" I asked.
He glanced at me with dislike. "Yeah. They looked a lot like a torch. It was
"Mark," said Cassie. "From the beginning?"
"Someone carrying a torch cut across the site, from the estate towards the road. That's it. All I saw was the torch beam."
"What time?"
"I wasn't looking at my watch. One, maybe? A little before?"
"Think back. Could you tell anything about them at all-maybe their height, from the angle of the torch?"
He thought, eyes narrowing. "Nah. It looked fairly low to the ground, but the dark fucks up your sense of perspective, yeah? They were moving slow enough, but anyone would; you've seen the site, it's all ditches and bits of wall."
"Big torch or small?"
"Small beam, not that strong. It wasn't one of those big heavy things with the handle. Just a little torch."
"When you first saw it," Cassie said, "it was up by the estate wall-where, at the end farthest from the road?"
"Somewhere around there, yeah. I figured they'd come out of the back gate, or maybe over the wall." The back gate of the estate was at the end of the Devlins' street, only three houses away. He could have seen Jonathan or Margaret, slowed down by a body and looking for a place to leave it; or Katy, slipping through the dark to meet someone, armed with nothing but a torch-beam and a house key that would never be able to take her home.
"And they went out to the road."
Mark shrugged. "They cut down that way, diagonal across the site, but I didn't see where they ended up. The trees got in the way."
"Do you think whoever it was saw your fire?"
"How would I know?"
"OK, Mark," Cassie said, "this is important. Did you see a car go past around that time? Or maybe a car stopped on the road?"
Mark took his time. "Nah," he said, finally and definitely. "A couple went past when I first got there, but nothing after about eleven. They go to bed early around there; all the lights on the estate are out by midnight."
If he was telling the truth, then he had just done us a huge favor. Both the kill site and the secondary scene-wherever Katy's body had been hidden through Tuesday-were almost definitely within walking distance of the estate, quite probably on it, and our field of suspects no longer included most of the population of Ireland. "Are you sure you would have noticed if a car had gone past?" I asked.
"I noticed the torch, didn't I?"
"Which you've only just remembered," I said.
His lip curled. "My memory's grand, thanks. I didn't think it was important. This was
At this point Bernadette, the squad administrator, tapped on the interview-room door; when I opened it, she said disapprovingly, "Detective Ryan, there's a telephone call for you. I told the person you couldn't be disturbed, but she said it was important." Bernadette has been with Murder for something like twenty-four years, her entire working life. She has a petulant marsupial face, five work outfits (one for each day of the week, which is helpful if you're too tired to remember what day it is) and, we all think, a Smithers-style hopeless passion for O'Kelly. There's a squad sweepstakes on when they'll finally get together.
"Go ahead," said Cassie. "I can finish up here-Mark, we just need to take your statement. Then we can give you a lift back to work."
"I'll take the bus."
"No you won't," I said. "We need to verify your alibi with Mel, and it's not exactly verification if you have a chance to talk to her first."
"For fuck's
"Don't worry, we will," I said cheerfully, and left him and Cassie to it.
I went back to the incident room and waited for Bernadette to put the call through, which she did in her own time, to show me it wasn't her job to come looking for me. "Ryan," I said.
"Detective Ryan?" She sounded breathless and bashful, but I knew the voice instantly. "It's Rosalind. Rosalind Devlin."
"Rosalind," I said, flipping my notebook open and hunting for a pen. "How are you?"
