Idling at curbside in the quiet Charlestown neighborhood, a few homes down from the house of Patrick Valentine, the car heater blowing precious warmth, she tallied what little she did know and decided Sarah's concern was far from unwarranted.

Valentine obviously knew how to circ.u.mvent channels. Older by around a decade than the oldest confirmed Helverson's subject, he had gotten himself diagnosed without betraying his anonymity. He exercised what appeared to be unlimited access to medical and research records, and on his own had managed to uncover an adult Helverson's female and shield her from identification as well. By use of the mail, he toyed with the psyches of volatile people, exhibiting the aloof disregard of a sociopath.

These were obvious. Then there were the unconfirmable rumors: the guns, the missiles, and most repugnant, his planned foray into eugenics. G.o.d help any child conceived under his procurement.

And Clay, you knew at least some of this, you had to know to want to get this far in the first place, you knew and you lied to me about it.

Two days ago, after awakening to the news of his vanishing, she and Sarah had sat in their motel room and, over coffee, tried to choose a next move that would be best for everyone. They could, of course, return to Denver, then Tempe, resuming their lives and never knowing what had become of Clay. But neither had any doubt that he would continue on to Boston. The only issue was whether or not they should follow.

He had left no note, no reason for his abandoning them, and while it hurt, she had to remind herself he would have meant no malice by it. Likely he had been driven by pain, by shame, she and Sarah continual reminders of what he'd faced in himself at Kendra Madigan's. If they continued together, Adrienne surmised, he would look at them and fear they now saw him as something truly lost, whose irredeemable nature was a genetic mandate, with no more hope of a cure than a malignancy whose tendrils were braided through the brainstem.

On his own, at least no one need suspect that but himself.

They would follow, they decided. They would follow and at least let him know that their opinion of him had not changed, not on the basis of a psilocybin vision that may or may not have been valid. That Clay understand she would never, could never, give up on him was crucial, and if it was her final gift, then let him at least be the one to tell her so. She demanded little for herself when it came to patients - and Clay had become so much more - but he owed her this much.

But they could not follow without at least some idea of his destination, and her only key was Timothy Van der Leun. His phone number was unlisted with Indiana Bell information, but her notebook computer still had access to the mainframe at Arizona a.s.sociated Labs, and she found it on file there. Timothy's voice, once he consented to answer his phone early that afternoon, had come from the bottom of a dead soul's gorge.

"I need your help. You're the only one who can help me," she had explained. "I brought Clay Palmer to Indianapolis and now I need to find him again because he needs help..."

"Who?" He'd sounded confused, feverish, so she had to tell him again, Clay Palmer, the one who came to see you last Friday, New Year's Eve. "Oh. Him. Right," Timothy had said. "I remember now." Then, in a thickened voice that nearly caused her to shudder, "Good scars. He had good scars."

She had pleaded and prodded and cajoled, on the theory that having been diagnosed years before Clay, Timothy might already have been contacted by the mysterious mentor in Boston. So long as she could keep him focused, he'd had ample tales to tell, information to share. In his more lucid moments he sounded more forsaken than insane, full of desperate grat.i.tude for a woman to talk with, who valued his opinion on anything, and she tried not to think of what he must look like, smell like, his skin a burnt patchwork of self-made sores.

She tried not to think of his inevitable fate.

So through the ragged clouds of snow and hostility they had driven to Boston, had gotten a hotel room, had acquired maps and charted out what was where. And if Clay wasn't with Patrick Valentine after all, if he had instead disappeared into the frozen mists like the misbegotten outcast of Mary Sh.e.l.ley's most famous novel, well ... perhaps it really would be time to pack in their best intentions and head for home. For the mountains, then the desert.

"Five more minutes," Adrienne said. "Then we'll check."

"Okay."

"Maybe they're asleep. You know the kind of hours he keeps, sometimes."

"I know," said Sarah. "I know."

She reached across to ma.s.sage the back of Adrienne's neck. In her lap was paper and pen, resting upon the flat of a book, with which she had whiled away their forty-five-minute stakeout. Sarah had filled it with experimental addresses for herself, seeing the way her name looked conjoined with cities and states all over the country: Sarah Lynn McGuire, 123 Fogbound St., Eugene, OR. Sarah Lynn McGuire, 456 Potato Lane, Boise, ID. She did this sometimes, in coffeehouses and comedy clubs, did it the way others doodled stick figures or hearts or future fortunes, Sarah indulging basic wanderl.u.s.t. "You never know," Adrienne once heard her tell someone who didn't understand, "maybe I'll write one and it'll be like a talisman. I'll look at it and the match will be so perfect, I'll just know it's a place I have to be."

I want to go to these places, too, Adrienne thought now. However many may seize you, I want to try them on with you and see how they fit us both. She really hoped she meant that, would mean it tomorrow and next week and a year from now, and that it wasn't just the wintry miles of failure and desolation talking.

"Okay," Adrienne said. "Time's up."

She put the car into gear, rolled ahead and down the street, to the house that Valentine built. They got out and picked their way along the front walk, up to the dark-windowed, two-story Cape Cod. Beneath its snowy blanket it looked sinister, she decided, as if it had something to hide.

"I had an optimistic thought," she said quietly, watchful. "If Clay's been here, now that he's made the trip and confronted his unknown, maybe it satisfied something in him and he'll be ready to leave."

Sarah nodded and raised one hand, pulling off her mitten so Adrienne could see her crossed fingers.

They mounted the porch. Rang the doorbell, and when that failed to rouse anyone, began to pound until she realized, no, no one was here, and selfishly, this brought relief. They retraced their steps, and she wondered if Valentine - or Clay - might later notice their prints and wonder like paranoiacs about what mysterious pair had come knocking.

"Well, there's always the other place downtown," Sarah said. "We could see if that's still going." She tossed a hasty s...o...b..ll at Adrienne before she could regain the shelter of the car. "If we time it right, maybe they'll even invite us to stay for dinner."

Thirty-Six.

The world was full of asylums, all kinds: those into which you were committed, those you carried around inside, those you let others build for you. Clay watched the first flakes of late afternoon snow drifting past the nineteenth floor and wondered if Valentine even realized what he had created here: just another asylum.

Though it was not without its appeal. At the moment the woody resin scent of marijuana smoke hazed the air. In this asylum they prescribed their own drugs and Valentine didn't seem to mind. A chromo mute could surrender here, trudge out onto the balcony like a beaten pontiff and tell the world, Enough, you win, I'll never be what you want, only what you deserve, then come back inside and wait to age another day.

He and Valentine had dropped by two hours ago, a follow-up to last night's visit, and this time Ellie's gaze lingered on his eyes instead of looking him up and down as a whole specimen. Just beyond her, Daniel Ironwood was taking in every move, and had wandered up even before Clay got his field jacket off, taller by a couple of inches and making sure Clay knew it.

"I meant to ask last night, what happened to your face?" Daniel pointed to the raggedly parallel scabs.

"I cut myself eating," Clay told him.

Ellie appeared borderline sympathetic. "Those look painful as h.e.l.l," then she shot a sporting glance at Daniel that he missed seeing. "I could kiss it to make it better, but Patrick says you don't like to be touched."

Daniel straightened, striving for still more height, crossed his arms before his chest. "Why don't you get it over with and kiss his a.s.s instead?"

"Well that's half-profound." She scruffed both hands across the cropped sidewalls of her hair and up through the length, as if she were about to pull it out. "Look, Jeopardy! should be on TV in a few minutes. If you want, I'll be happy to spend some more quality time with you, and if you're really really nice between now and then, this time I promise not to count how many times your lips move and no sound comes out."

"f.u.c.k you," and Daniel stalked off down the hall toward the bathroom.

"Yeah, that's what you're being paid for, isn't it?" Ellie called over his shoulder. "Maybe I should tell Patrick I'm not quite getting his money's worth."

The bathroom door slammed and Valentine stood gloating, as if everything were some grand joke that he had told with perfect timing, and then Ellie turned to him and began to complain of how brutal Daniel had been last night, and she had no reason to believe he would alter his tactics.

"It's only for tonight and tomorrow night," Valentine said, "and after that you don't have to see him if you don't want to. You can put up with him for two more nights."

Clay supposed it was at this point that he began to think, Wait, there's something going on here I don't know about, something he's not telling me, and then Ellie said that when they first met she'd actually thought Daniel was fairly sedate and even-tempered for a Helverson's guy, and Valentine smiled his tightest control-freak smile.

"If you need somebody to blame," he said, "blame Clay. Daniel just thought he was coming in for the same casual s.e.x he's always had. But now? Now he's taking a lot more personal interest in sowing that seed. He can't help it, it's sperm compet.i.tion."

"Could you be a little more manipulative, is that possible?" Ellie twirled one finger around a strand of hair and plucked it out. "Anyway, I'm not looking to blame anybody, all I want is for Daniel to quit acting like he's trying to crack my pelvis in two."

"Then go back and start being nice to him. Get him to quit sulking in the bathroom."

She barked another of her strange, incredulous laughs. "He went in by himself, let him decide when he wants to come out. Why should I have to coax him?"

Valentine took a step forward and leaned into Ellie's face. "Because if you don't, I'll blacken your eye," then he reached beneath his cable-knit sweater to draw out a gun that Clay hadn't realized he'd been carrying, a heavy revolver that captivated by sheer presence and oiled, black sheen. He spun the cylinder and let the gun dangle errantly from his fist. "And if that doesn't move you, then we'll play the game again, like we did that one time."

Ellie drew herself together, very cool, very aloof, her lips compressing into an expression almost prim as she regarded him for a few moments. "Okay, Patrick. You can have it your way." She began to scoot toward the hall. "You always do."

And when Clay followed Valentine over to sit with him in the living room it wasn't so much that he wanted to, as that he hoped for some explanation that would shed full light on this nineteenth floor cuckoo's nest. Certainly he didn't belong here, and probably he would have left by now if he had anywhere to go, anything to do ... any reason to leave and live for. He was beginning to get a distinct feeling of being used, rather than educated.

"What is this all about, here?" Clay asked. "What is it you want out of those two?"

And when Valentine began to rhapsodize about conception, and breeding stock, and what might the offspring be like parented by not one but two Helverson's subjects, it seized Clay's imagination with a dread so palpable he really feared he might be ill.

Helverson's times two? Helverson's squared? Or might the result be a mutation fouler still, never before seen, never antic.i.p.ated, grotesque potency distilled through the generations.

"You'd do that to some kid deliberately?" he whispered.

What a horrible thing, what a perfectly horrible thing, and he recalled those times with Erin when they had lain in bed and the thought of siring a child was the worst act he could think of, the worst crime he could commit upon innocence, even upon a world as corrupt as he knew theirs to be.

"You're a monster. You're a complete monster." It might have stung the man, for while he didn't flinch, he c.o.c.ked his head to one side almost as if he didn't comprehend. It might have hurt him ... but it was so hard to tell.

Clay stood to turn his back on the man, nearly stumbling on his way to the sliding balcony door, where he leaned against the gla.s.s and stared at the snow beginning to fall. When he heard Valentine behind him he knew if the guy so much as rested a hand on his shoulder, that would be it, he would go for his eyes.

"No. I'm not," was all the man said, all he did. "I'm just the first."

But there Clay stayed, Valentine leaving him be, an hour or more pa.s.sing as life went on too slowly, as Ellie and Daniel came back and seemed at truce, and one of them asked, "So what's wrong with him?" but went unanswered. They began to smoke from her stash, peace pipe maybe, and Clay watched the leaden sky go darker with the first gloom of dusk.

Then he heard something he had never expected to hear, not in this place, with all four of them as isolated from one another as they were from the world at large: He heard the doorbell.

Adrienne's gaze fell naturally upon Clay as soon as they were let in. Fifteen feet away, across this penthouse apartment, there was true pain in what she saw: Oh, he's worse, he'd not weathered the trip north well at all. Only three days had pa.s.sed since she'd seen him, but he appeared thinner, paler, his eyes burning gray hollows. The only genuine color in him came from the savaging he had given the side of his face: the red badge of desperation.

Only then did she truly notice the others.

She thought, oddly, of their brief discussion about Salvador Dali, wondering if Sarah did likewise, for here was surrealism: encountering four faces so wholly similar, staring back. It was academic to see pictures; visceral to enter a home and see a quartet in which individuality appeared sacrificed to a prevailing stigma.

She caught her breath. See them, and one could find it too easy to believe in a purpose underlying their births. Given the suspicion and hostility in at least some of those eyes, perhaps it was precisely as Clay had said. There was something eerily more than human in all those streamlined faces turned her way, like lizards catching sound of a threat.

"Are you sure you're in the right place?" the girl asked. Ellie. Her name, Timothy had said, was Ellie.

"No doubt." Sarah took another step, hands fisted into the slash pockets of her down vest. "There's no other place like this, is there?"

Across the room, their elder rose from the chair in which he seemed to have been brooding for a while. Patrick Valentine had a glare that could cause ulcers.

"Who are you?" he asked.

Adrienne lifted her hand toward Clay, framed against a gla.s.s door, a skyline, a thickening snowfall. "I've been Clay's doctor since September."

"Rand. Oh, right." Valentine spared Clay a perfunctory glance, then regarded her with dismissal. "How proud you must be. He looks wonderful."

She ignored him, or tried, because he was obviously the sort of man who would miss nothing, who understood what would hurt and how to exploit it, a man who knew where all the nerves lay. Don't listen to him. There was only Clay here, she decided, and spoke his name but nothing more, for everything had abandoned her. All logic, all persuasion ... gone.

But maybe it was better this way. Maybe she belonged mute. She needed to say nothing for Clay to see how far she had come, how low she had fallen. He would realize why they had come - that no matter what he did, she still refused to let hope die.

It should have been a simple decision for him. He obviously had come here and found more unhappiness than answers.

And yet...

He hesitated.

"Do we need to talk," she said, finding resolve, "or would that even do any good any more?"

"It's not that simple," said Clay, and why did he insist on making it so difficult for himself? Couldn't he for once just admit the mistake and redress it by taking the quick way out? But no, he couldn't bring himself to make it that easy.

Sarah caught her eye then, Sarah sad and emptying right there beside her. It's us, Adrienne realized. It's the way he sees us, to him we must seem so complete together, that to be with us magnifies every bit of stability and unity he's lacking. He's reminded of it every moment he's with us, and he doesn't see the disagreements or the squabbles, but even if he did it might make everything even more genuine, because he'd realize they never last long...

It's us. We're as much at fault as anyone.

Sarah fumbled blindly for her hand, ever intuitive, sensing that sudden failure in her. She took a step forward to pick up the slack.

"As long as you never see the sun," she said, with a smile - if anyone could turn his awful pallor into a gentle joke it was Sarah - "would you like to come back with us as a consultant? I've got this wild idea for part of my thesis, I want to go looking for cave paintings in old shut-down factories, and you're the only expert I know."

Clay's face softened, wistful, transported to another day. He looked almost hopeful. "Where are you going to start?"

Sarah shrugged. "South Dakota, maybe? If you think it's worth the trip. I figure it's worth a look."

Adrienne didn't immediately catch on. South Dakota? Then the memory fired: Where Erin went home to, and if Sarah was the one to talk Clay down from here instead of her, fine, more power to her, whatever worked. And it appeared that she really might, for he looked upon Sarah with as much trust as she had ever seen him grant.

None of which was lost on Valentine. He would look for these weaknesses as a rule. Soft underbellies were made to be torn.

"And what then, Clay, a week from now, a month?" he said. "Is she going to marry you? You think you're going to set up some happy home in the mountains? Raise normal babies?"

Adrienne stared. Whatever's pa.s.sed between the two of them ... Valentine doesn't understand it at all. He can't read it right because he's probably never had a friend in his life.

"If you think anything even remotely like that is going to happen for you," Valentine said, "you're living in a fantasy world that'll destroy you when you get burned out of it."

Bristling, Sarah appeared to have had about enough. "You're the last man on earth to lecture anyone on fantasy worlds," she told him. "You're the little man behind the curtain in Oz."

Against the near wall, Ellie stuttered into laughter, and the other man - Adrienne wasn't even sure which one this was - turned on her with alarm, Shut up, shut UP! in his taut features. Adrienne had almost made a similar observation, but to Sarah alone, discreetly. How ironic: All day Sarah had been the one to preach caution, to fret about Adrienne angering this Machiavellian tyrant.

"I'll take my chances," said Clay, and moved toward his coat.

Valentine nodded, muscles bunching in his jaw. "Chance is the stuff of life."

It happened very abruptly.

Clay was halfway to his coat when Valentine went kinetic, empty hand plunging beneath his sweater and emerging full, mighty as Thor with a hammer. He swung out the revolver's cylinder, and no one could have missed hearing the clicking metallic whir as he spun it. Pivoting then, slapping the cylinder back into place and raising his hand, he thrust the pistol forward as if he were launching a javelin, every motion so smooth and fluid that Adrienne was not so much frightened as insanely curious to know how often he had practiced this.

"Snake in the gra.s.s!" he shouted as the gun reached its apex, which made no sense to her at all. She met his eyes, and no one could have looked more surprised than Valentine when the gun blasted out a single devastating shot. At once he erupted with a triumphant whoop.

With every sense raw, unguarded, sensation became immense. The sound of bullet striking skin was orchestral; the blood that splashed her felt scalding. The hand clutching her arm was a fearsome claw, and she looked over, looked down, to see the side of Sarah's throat.

Gone. Just gone.

Together they fell, Sarah's weight dragging her down. Sarah began to choke before they hit the floor, her eyes gaping and glazed in disbelief. An anemic cry warbled past Adrienne's lips as her hands trembled, then groped in a frantic attempt to staunch the flood from Sarah's throat. It sprayed, it flowed. It pulsed and gushed.
