This should hardly have come as a surprise, but it still felt like he’d slapped me straight across the face. He felt for his cigarette case. “I’d prefer that the others not find out who you are. I think you can imagine how badly it would upset them. I admit I’m not sure how to accomplish this, but surely you and Detective Mackey have a get-out clause in place, no? Some story you worked out to extricate you without raising any suspicions?”

  It was the obvious thing to do, the only thing. You get burned, you get out, fast. And I had everything a girl could ask for. I had narrowed our suspects down to four; Sam and Frank would be well able to take it from there. I could get around the fact that this wasn’t on tape: disconnect the mike wire and claim it was accidental—Frank might not believe me, exactly, but he wouldn’t care—report back the bits of this conversation that suited me, bounce back home immaculate and triumphant and take a bow.

  I never even considered doing it. “We do, yeah,” I said. “I can get out of here on a couple of hours’ notice without blowing my cover. I’m not going to, though. Not till I find out who killed Lexie, and why.”

  Daniel turned his head and looked at me, and in that second I smelled danger, clear and cold as snow. Why not? I had invaded his home, his family, and I was trying to wreck them both for good. Either he or one of his own had already killed a woman for doing the same thing on a lesser scale. He was strong enough to do it and very possibly smart enough to get away with it, and I had left my gun in my bedroom. The trickle of water sang on at our feet and electricity fizzed through my back, down into the palms of my hands. I held his eyes and didn’t move, didn’t blink.

  After a long moment his shoulders shifted, almost imperceptibly, and I saw his gaze turn inwards, abstracted. He had rejected that idea: he was moving towards some other plan, his mind clicking through options, sorting, classifying, connecting, faster than I could guess. “You won’t do it, you know,” he said. “You assume that my reluctance to hurt the others gives you an advantage—that, as they’ll continue to believe you’re Lexie, you have a chance at getting them to talk to you. But believe me, they’re all very well aware of what’s at stake. I’m not talking about the possibility of one or all of us going to jail; you have no evidence pointing towards any one of us in particular, no case against us either individually or collectively, or you’d have made your arrests long ago and this charade would never have been necessary. In fact, I’m willing to bet that, until a few minutes ago, you weren’t actually certain that your target was within Whitethorn House.”

  “We kept all lines of inquiry open,” I said.

  He nodded. “As things stand, jail is the least of our worries. But take the situation, for a moment, from the others’ point of view: assume that Lexie is alive and well and safely home again. If she were to find out what happened, it would mean the ruin of everything we’ve worked for. Suppose she were to learn that Rafe, to pick one of us at random, had stabbed her—had almost cost her her life. Do you think she could continue to share that life with him—without being afraid of him, without resenting him, without using this against him?”

  “I thought you said she was incapable of thinking about the past,” I said.

  “Well, this is in a slightly different league,” Daniel said, a little acidly. “He could hardly assume that she would dismiss this as if it were some spat over whose turn it was to buy milk. And even if she did, do you suppose he could look at her every day without seeing the constant risk she presented—the fact that at any moment, with one phone call to Mackey or O’Neill, she could send him to jail? This is Lexie, remember: she could make that call without realizing for a second the magnitude of that action. How could he treat her as he always has, tease her, argue with her, even disagree with her? And what about the rest of us, walking on eggshells, reading danger into every look and every word that passed between the two of them, always waiting for the tiniest misstep to detonate the land mine and blow everything to smithereens? How long do you think we’d last?”

  His voice was very calm and even. Lazy curls of smoke were trickling from his cigarette, and he lifted his head to watch as they spread and wound upwards, through the fluttering bars of light. “We can survive the act itself,” he said. “It’s the shared knowledge of the act that would destroy us. This may sound odd, especially coming from an academic who prizes knowledge above almost anything, but read Genesis, or, even better, read the Jacobeans: they understood how too much knowledge can be lethal. Every time we were in the same room, it would be there among us like a bloody knife, and in the end it would slice us apart. And none of us will allow that to happen. Since the day you came into this house, we’ve put every drop of energy we have into preventing it, into restoring our lives to normality.” He smiled slightly, one eyebrow lifting. “So to speak. And telling Lexie who stabbed her would end any hope of that normality. Believe me, the others won’t do it.”

  When you’re too close to people, when you spend too much time with them and love them too dearly, sometimes you can’t see them. Unless Daniel was bluffing, he had made one last mistake, the same one he had been making all along. He was seeing the other four not as they were but as they should have been, could have been in some softer-edged and warmer world. He had missed the stark fact that Abby and Rafe and Justin were already disintegrating, they were running on empty; it stared him in the face every day, it passed him on the stairs like a cold breath and slipped into the car with us in the mornings and sat dark and hunched between us at the dinner table, but he had never once seen it. And he had missed the possibility that Lexie had had secret weapons of her own, and that she had willed them to me. He knew his world was falling apart, but somehow he was still seeing the inhabitants untouched amid the wreckage: five faces against drifting snow on a day in December, cool and luminous and pristine, timeless. It was the first time in all those weeks that I remembered he was much younger than me.

  “Maybe not,” I said. “But I’ve got to try.”

  Daniel leaned his head back against the stone of the wall and sighed. All of a sudden, he looked terribly tired. “Yes,” he said. “Yes, I suppose you do.”

  “It’s your call,” I said. “You can tell me what happened right now, while I’m not wired: I’ll be gone by the time the others get home, and if it comes to arrests it’ll be your word against mine. Or I can stay here, and you can take the chance that I’ll get something on tape.”

  He ran a hand over his face and straightened up, with an effort. “I’m perfectly aware, you know,” he said, glancing at his cigarette as if he had forgotten he was holding it, “that a return to normality may not be possible for us, at this point. I’m aware, in fact, that our entire plan was probably unfeasible right from the start. But, like you, we have no choice but to try.”

  He dropped the smoke on the flagstones and put it out with the toe of his shoe. That frozen detachment was starting to slip into place over his face, the formal mask he used with outsiders, and there was a crisp note of finality in his voice. I was losing him. As long as we were talking like this, I had a chance, no matter how small; but any second now he was going to get up and go back indoors, and that would be the end of that.

  If I had thought it would work, I would have got down on my knees on the flagstones and begged him to stay. But this was Daniel; my only chance was logic, cold hard reason. “Look,” I said, keeping my voice even, “you’re raising the stakes a whole lot higher than they need to be. If I get something on tape, then, depending what it is, it could mean jail time for all four of you—one on murder, and three on accessory or even conspiracy. Then what’s left? What have you got to come back to? Given the way Glenskehy feels about you, what are the odds that the house will even be standing when you get out?”

  “We’ll have to take that chance.”

  “If you tell me what happened, I’ll fight your corner all the way. You’ve got my word.” Daniel would have had every right to give me a sardonic look for that, but he didn’t. He was watchin
g me with what appeared to be mild, polite interest. “Three of you can walk away from this, and the fourth can face manslaughter charges instead of murder. There wasn’t any premeditation here: this happened during an argument, nobody wanted Lexie to die, and I can vouch for the fact that all of you cared about her and that whoever stabbed her was under extreme emotional duress. Manslaughter gets maybe five years, maybe even less. Then it’s over, whoever it is gets out, and you can all four put this whole thing behind you and go back to normal.”

  “My knowledge of the law is patchy,” Daniel said, leaning over to pick up his glass, “but as far as I know—and correct me if I’m wrong—nothing said by a suspect during questioning is admissible in evidence unless the suspect has been cautioned to that effect. Out of curiosity, how are you planning to administer a caution to three people who have no idea that you’re a police officer?” He rinsed out the glass again and held it up to the light, squinting, to check that it was clean.

  “I’m not,” I said. “I don’t need to. Whatever I get on tape was never going to be admissible in court, but it can be used to get an arrest warrant and it can be used in a formal interview. How long do you think Justin, for example, will hold out if he’s arrested at two in the morning and questioned by Frank Mackey for twenty-four hours, with a tape of him describing Lexie’s murder playing in the background?”

  “An interesting question,” Daniel said. He tightened the cap on the whiskey bottle, placed it carefully on the bench beside the glass.

  My heart was going like hoofbeats. “Never go all in on a bad hand,” I said, “unless you’re absolutely positive you’re a stronger player than your opponent. How sure are you?”

  He gave me a vague look that could have meant anything. “We should go in now,” he told me. “I suggest we tell the others that we spent the afternoon reading and recovering from our hangovers. Does that sound about right to you?”

  “Daniel,” I said, and then my throat closed up; I could hardly breathe. Until he glanced down, I didn’t even realize that my hand was on his sleeve.

  “Detective,” Daniel said. He was smiling at me, just a little, but his eyes were very steady and very sad. “You can’t have both. Don’t you remember what we were talking about, just a few minutes ago—the inevitability of sacrifice? One of us, or a detective: you can’t be both. If you had ever truly wanted to be one of us, wanted it more than anything else, you never would have made a single one of those mistakes, and we wouldn’t be sitting here.”

  He laid his hand over mine, removed it from his sleeve and placed it in my lap, very gently. “In a way, you know,” he said, “strange and impossible though it may seem, I very much wish you had chosen the other way.”

  “I’m not trying to ruin you,” I said. “There’s no way I can claim to be on your side, but compared to Detective Mackey, or even Detective O’Neill ... If it’s left up to them—and unless you and I work together, it will be; they’re the ones running the investigation, not me—all four of you will be serving the maximum for murder. Life sentences. I’m doing my best here, Daniel, not to let that happen. I know it doesn’t look like it, but I’m doing everything I can.”

  A leaf had fallen from the ivy into the trickle of water and got caught on one of the little steps, shaking against the current. Daniel picked it out carefully and turned it between his fingers. “I met Abby when I started Trinity,” he said. “Quite literally; it was on registration day. We were in the exam hall, hundreds of students queuing for hours—I should have brought something to read, but it hadn’t occurred to me that it would take so long—shuffling along under all those gloomy old paintings, and everyone whispering for some reason. Abby was in the next queue. She caught my eye, pointed to one of the portraits and said, ‘If you let your eyes go loose, doesn’t he look exactly like one of the old fellas out of the Muppets?’ ”

  He shook water off the leaf: droplets flying, bright as fire in the crisscrossing sunbeams. “Even at that age,” he said, “I was aware that people found me unapproachable. I had no problem with that. But Abby didn’t seem to feel that way, and that intrigued me. She told me later that she was almost petrified with shyness, not of me in particular but of everyone and everything there—an inner-city girl from foster homes, thrown in amongst all those middle-class boys and girls who took college and privilege so completely for granted—and she decided that, if she was going to pluck up the courage to talk to someone, it might as well be the most forbidding-looking person she could find. We were very young then, you know.

  “Once we’d finally got ourselves registered, she and I went for a coffee together, and then we arranged to meet again the next day—well, when I say arranged, Abby told me, ‘I’m going on the library tour tomorrow at noon, see you there,’ and walked off before I could answer either way. By that time I already knew that I admired her. It was a novel sensation, for me; I don’t admire many people. But she was so determined, so vivid; she made everyone I had met before seem pale and shadowy by comparison. You’ve probably noticed”—Daniel smiled faintly, glancing up at me over his glasses—“that I have a tendency to keep myself at some distance from life. I had always felt that I was an observer, never a participant; that I was watching from behind a thick glass wall as people went about the business of living—and did it with such ease, with a skill that they took for granted and that I had never known. Then Abby reached straight through the glass and caught my hand. It was like an electric shock. I remember watching her walk off across Front Square—she was wearing this awful fringed skirt that was much too long for her, she looked drowned in it—and realizing that I was smiling . . .

  “Justin was on the library tour the next day. He hung back a step or two behind the group, and I wouldn’t even have noticed him if it hadn’t been for the fact that he had a hideous cold. Every sixty seconds or so he came out with this enormous, explosive, wet sneeze, and everyone would jump and then snicker, and he would turn an extraordinary shade of beetroot and try to disappear into his handkerchief. He was obviously excruciatingly shy. At the end of the tour Abby turned around to him, as if we’d known one another all our lives, and said, ‘We’re going for lunch, are you coming?’ I’ve seldom seen anyone look so startled. His mouth popped open and he mumbled something that could have meant anything, but he went over to the Buttery with us. By the end of lunch he was actually speaking in full sentences—and interesting ones, too. We’d read a lot of the same things, he had some insights into John Donne that had never occurred to me . . . It hit me, that afternoon, that I liked him; that I liked both of them. That, for the first time in my life, I was enjoying the company of others. You don’t strike me as the kind of person who’s ever had difficulty making friends; I’m not sure you can understand quite what a revelation that was.

  “It took us until classes started, the next week, to find Rafe. The three of us were sitting at the back of a lecture room, waiting for the lecturer to show up, when all of a sudden the door beside us flew open and there was Rafe: dripping with rain, hair plastered to his head, fists clenched, obviously straight out of some traffic mess and in a horrible mood. It was a pretty dramatic entrance. Abby said, ‘Check it out, it’s King Lear,’ and Rafe whipped around on her and snarled—you know how he gets—‘How did you get here, then—in Daddy’s limo? Or on your broomstick?’ Justin and I were taken aback, but Abby just laughed and said, ‘By hot-air balloon,’ and pushed a chair towards him. And after a moment he sat down and muttered, ‘Sorry.’ And that was that.”

  Daniel smiled, down at the leaf, a private little smile as tender and amazed as a lover’s. “How did we ever put up with one another? Abby talking nineteen to the dozen to hide her shyness, Justin half smothered under his, Rafe biting people’s heads off right and left; and me. I was terribly serious, I know. It wasn’t until that year, really, that I learned how to laugh . . .”

  “And Lexie?” I asked, very softly. “How did you find her?”

  “Lexie,” Daniel said. The smile ripple
d across his face like wind on water, deepened. “Do you know, I can’t even remember the first time we met her? Abby probably can; you should ask her. All I remember is that, by the time we had been postgrads for a few weeks, she seemed to have been there forever.”

  He put the leaf down gently on the bench beside him and wiped his fingers on his handkerchief. “It always took my breath away,” he said, “that the five of us could have found one another—against such odds, through all the layers of armored fortifications each of us had set up. A lot of it was Abby, of course; I’ve never known what instinct led her so unerringly, I’m not sure she knows herself, but you can see why I’ve trusted her judgment ever since. But still: it would have been so heart-stoppingly easy for us to miss one another, for me or Abby to show up an hour later for registration, for Justin to refuse our invitation, for Rafe to be just that little bit snippier so that we backed off and left him alone. Do you see now why I believe in miracles? I used to imagine time folding over, the shades of our future selves slipping back to the crucial moments to tap each of us on the shoulder and whisper: Look, there, look! That man, that woman: they’re for you; that’s your life, your future, fidgeting in that line, dripping on the carpet, shuffling in that doorway. Don’t miss it. How else could such a thing have happened?”
