North this trip, a direction only a fool would take this time of year, but fools could be mad and could even be holy, and the paths of holy madmen led somewhere.

He would find one such path - he had to.

Unburdened by his car, on foot as seemed proper, Clay wore layers of clothes and carried only what fit in the pockets of his heavy field jacket. He trekked across the city for an hour and blocked out its roar with his Walkman tape player and earphones. The night was cold against his face but at least it was dry, and finally he caught a bus, boarding it in a swirling cloud of diesel stink and riding with fellow pa.s.sengers who lived in their tiny islands of air and met no one's eyes. He rode as far north as he could, then got off and trudged several blocks to the highway.

Three in the morning and he caught a lift with an eighteen-wheeler. Anyone hitching in December must need the ride. Might be crazy, but not dangerous crazy, or so the driver told Clay.

Rolling through the night, the ribbon of highway far below, with a billion cold pinp.r.i.c.k stars overhead. He had burned before, so maybe this trip he should freeze. He would turn west eventually, climb as far into the mountains as he could, feel them rise majestic and savage beneath his feet, and the sooner, the better. It had become an urgent need to stand dwarfed by trees that grew as plentiful as gra.s.s, and between earth and stars, bare himself to a roaring winter wind that would try to strip him naked and turn him blue. Perhaps he could survive only minutes, seconds even - but the seconds would be his. His tonic. His truth.

If it left him nothing but his name, turned the rest of him into a blank scoured clean by wind and ice and snow, perhaps that might be best. He could try building again.

Around four, the driver veered into the rest stop before the Fort Collins turnoff to catch a nap before continuing, so Clay went striding across the lot with half a moon in the west, half a beacon, as all around him the big rigs grumbled like restless sleepers, snorting and farting into the sky. Diesel fumes burned his nose and he trudged into the silent rest stop, locked himself in a stall, and, sitting on the toilet, managed to sleep until an hour past dawn.

Clay hoofed west into Fort Collins. The sun was up and baked the night's chill out of the earth. Beneath his clothes he finally broke sweat. Fort Collins was a college town, he had been here before but couldn't recall why; thought it was a lot like Boulder, only less self-conscious about what it was and was not.

An oasis on the edge of the mountains - here he spent the rest of the morning, on into the afternoon. Found a sandwich shop where he pa.s.sed two hours pouring down coffee and silencing the dull hollow in his belly, reading the local free weeklies just so he looked as if he had something to do. Liking the feel of it all - the vagabond life really did suit him at times. He could watch the students who were wrapping up their semester and see the sleepless tension in their eyes, and felt like the freest man in town. Plenty of knowledge to go around, but did they really know how to think? A lot did not, he suspected, else they wouldn't be here, so ready to sacrifice themselves just to be content with such meager crumbs of lives once they were finished. No one to hire them and nothing to do.

Late afternoon, he ducked off a side street into a music store, We Sell New And Used, little hole-in-the-wall shop that smelled of dusty alb.u.m jackets and earlier incense, with walls half-papered over with do-it-yourself announcements. Clay prowled the shelves of ca.s.settes, missing Erin in a way he had not thought possible. Whatever it was they had, last night he might have wrecked it without saying a word, because he'd not said a word, not any words that really mattered.

Don't hurt, Erin. And don't hate me because I don't know how to keep you from it.

He found what he was looking for, a few tapes by Gene Loves Jezebel. All the same to him, he didn't really know their music, but Erin loved them; knew t.i.tles, lyrics, everything; they were a perennial favorite and that was good enough. He could play this through his Walkman and let it work whatever magic it might; make it easier for him to feel the s.p.a.ce at his side was a little less empty.

He selected one of the tapes by merit of artwork alone, took it to the counter and slid it to the guy on duty. Gave the short plastic carousel of promotional tapes a spin while waiting for the kid to ring him up.

The kid paused with his finger over the cash register, tape in hand. Loose hair to his shoulders, flannel over a concert T-shirt that one more washing would destroy. His narrowing eyes smacked of disapproval.

"Are you still listening to them?" he asked.

"Yeah," said Clay. "Are you still selling them for minimum wage?"

The kid smirked and did not answer, took his money, and Clay realized it was the hardest thing he'd done in weeks, giving his cash to this guy. The in-store music seemed to boost in volume, shrieking needles of sound. Clay wondered if the kid noticed the trembling of his hand when he took his change.

The kid did not bothering sacking the tape, just stood tall and superior and flipped it across the counter.

"Enjoy," he said. "d.i.c.k."

Clay slipped it into a roomy pocket, stood looking down at his shoes for a moment. They had carried him far in one night, but it was never far enough. Never. He looked up.

He put on his gloves.

"Problem?" the kid asked, with grossly exaggerated concern.

"Uh huh," he said, and punched the brat as hard as he could, felt the nose squash like a plum. Watched him buckle facedown onto the counter, then could not stop himself from grabbing the carousel of promo tapes and lifting it high. He clubbed him once, on the back of the head. Clubbed him again.

It might have been only one more time.

It might have been forty.

Twenty-Two.

She wasn't sleeping as well in Denver as she normally did in Tempe, at least not lately. When the phone rang, somewhere in the depths of the condo, it had no trouble ripping her from sleep, while Sarah dozed like a log, unfazed.

"Probably for you," Adrienne murmured.

She rolled out of bed, got her footing. Sought her robe that hung over the back of a chair, heavy flannel in deference to her first real winter in years; it looked like a horse blanket. Sarah pretended to find it a turn-on, dubbed it lingerie from Frederick's of Iowa.

The phone continued to shrill as she fumbled toward it in the dark. Maybe motherhood was like this, anything to quiet the noise in the dead of night, return to stasis. In the back of her mind she'd always thought she would like to give it a try, but now had to reconsider. A trial run like this and she felt more resentment than anything. Maybe she had no business taking care of a child; no business taking care of anyone.

Eleven or twelve rings, and she found the phone. How much more malevolent they sounded by night, by early morning, at - she squinted at the clock glowing in the kitchen - four-thirty in the morning? She said h.e.l.lo and waited, heard nothing but distant traffic, down the street or halfway around the world.

Then: "Adrienne?"

She straightened against the wall, everything coalescing into a phosph.o.r.escent pinpoint that burned like a welder's torch. Clay. Unaware, she wrapped the spiral cord around her free hand as if she could hang onto him that way, reel him back in.

"I'm glad you called," she said.

"Uh huh." His voice sounded thin and strained. "Can you come get me?"

"Sure." Automatic. "Where are you?"

"I think I might have killed someone."

Sarah had offered to drive but Adrienne more than wanted to, she needed to. It would leave that much less of her mind free for dread, for every second-guess that floated in from the dark in that predawn hour when nothing seems the same. When love feels sweeter and illness incurable.

Leaving a city behind, a weaving route of on-ramps and merge lanes; Sunday's dawn yet to come and Denver felt dead. Clouds had stolen in overnight to muddy the sky. Adrienne had to consciously stop herself from gnawing at her lower lip. She would show up in Fort Collins looking as if she'd been punched.

I think I might have killed someone.

What if he was right? He would be lost then, to himself and to her, even to his kind; another statistical casualty. If he really had become a danger, she should turn him in. While the doctor-patient relationship was nearly as sacrosanct as that of priest and confessing sinner, she had an ethical duty to the public's safety.

Ah, but she had bent ethics already. If the relationship was that confidential, what was Sarah doing coming along now; what was Sarah doing with full knowledge in the first place?

I am losing all my touchstones, she was forced to admit. I'm out here with only my conscience for a guide, and it's rebelling at nearly everything I used to think was sacred. Because none of that works this time.

She'd come to the conclusion that she was doing Arizona a.s.sociated Labs' dirty work. Their invasion of privacy under a pretense of providing care. And while those to whom she reported seemed satisfied with what she was sending in, the joke was really on them. She was not even giving full disclosure anymore.

Clay's outburst in which he demolished the bar stool? She had never told them, for fear she might be removed from the scene, that it was getting too dangerous; not in AAL's mercenary view, but possibly Ferris Mendenhall might rescind his cooperation in loaning her out. Likewise she had downplayed how extensive his break with her had been; feeding the hope, keeping it alive, Clay may come around any day. Much of the conversation in the abandoned factory, which Sarah had recounted for her, Adrienne had relayed as if it had been held with her instead, informally. See, I'm still getting some results. Clay's tale of the peppered moth, oh, how they had loved that a.n.a.logy. She was hip-deep in an ethical quagmire, but unable to convince herself that it was not justified on the most vital level: saving Clay.

If his chromosomes broke the rules, couldn't she?

"Things can't go on like this," Adrienne said, "not if he's going to derive any benefit and get control over himself."

Sarah sat bouncing her knee, holding a mug of coffee whipped together before they had left. "What else can you do that's that much different?"

"I don't know. It's the circ.u.mstances, mostly. They don't feel right to me. We dumped him right back into the same life that was creating most of his problems."

"Maybe he'd have problems no matter where he was."

"Maybe." Adrienne nodded. "Probably. If he's really hurt someone up there, it might be possible to commit him now, but..."

"But you really don't want to."

"I don't think it would help at all, I think it'd be giving him the final excuse he needs to destroy himself. I keep thinking I can make some difference." She scooted down in the seat, easing off her guard now that they were out of Denver; skinned a hand through her hair and looked at a couple of gold silken strands that came free. Great, on top of everything else I'm losing my hair. "I'm wondering now how far I'll go just to try to keep myself in place. I've already held things back at my own discretion, I've twisted things around. Do I draw the line at outright lies?"

After she no longer had access to Clay at all, how many more weeks - days, even - before she began fabricating entire reports, to keep from being recalled home? Turn his case history into fiction, just to avoid giving up on the idea of being part of it?

Sarah's hand, warmed from the mug, found its way to hers; lingered and gave a squeeze before withdrawing.

"Have you thought of hypnotherapy for him?" Sarah said.

"Not seriously, no." It was nothing for which she had ever trained. And while it had its merits, she had reservations that it would even be appropriate. Uncovering a forgotten past was not the issue, and posthypnotic suggestions generally worked better on concrete behavior patterns, not overall ways of relating to the world; thou shalt not smoke, thou shalt not eat to excess.

"He's big on finding out what that chromosome triplet means, you know," Sarah said.

"Trisome."

"Hmm?"

"It's called a trisome."

"Whatever." Sarah gulped at her coffee. "I don't think Clay cares half as much what it's called as he does finding out why it's happening."

"Well, don't we all."

"And not just to him, but to each of them. You know, ever since I talked to him in that factory -"

The factory; now there was a blister to poke. Clay had let Sarah share his inner sanctum when he probably would have waved his chair at Adrienne until she retreated. Jealous? h.e.l.l yes.

" - and he told me about the moths, that whole biological and environmental agenda under the surface, you know who I've kept thinking about?"

Adrienne gripped the wheel. This could only be weird. "Who?"

"Remember Kendra Madigan?"

She drew a blank for a moment, and then it hit her, hit her hard. "You've got to be kidding."

"No. I'm not. It might be an interesting thing to try with him, if he'd want to."

Adrienne, shaking her head, was adamant. "Interesting. That's a blithe way to put it. Especially when something like that is likely to do more harm than anything."

But this was Sarah she was talking to; typical Sarah, who now and then clung to the oddball and superst.i.tious because she wanted to believe in a shortcut, and she would not be dissuaded. They saw eye-to-eye on much, but here they parted company.

They had heard of Kendra Madigan even before she had come to Tempe for a lecture and debate at the university a year and a half ago. She had been written up in a one-page article Sarah had seen in Newsweek, and Psychology Today had humored her if nothing else.

A professor at the University of North Carolina at Chapel Hill, and a practicing hypnotist and psychologist, Kendra Madigan had written a book in which she claimed to have pioneered a hypnosis so deep it was possible to access the collective unconscious, the species memory that transcended the individual. No one of much note took her seriously, dismissing the technique as so much New Age hok.u.m, although they stopped short of accusing her of fraud. She was, at worst, deluded, her ideas all the more controversial for her use of natural hallucinogens on some subjects. Predictably enough, her reception at Arizona State had been mixed, both enthusiastically pro and skeptically con.

Naturally, Sarah had been enthralled.

"You know what it's like?" Sarah asked. "It's like you're just giving lip service to Carl Jung, and not really putting your money where your ideology is. How can you anchor yourself in Jung like you do and deny the collective unconscious?"

"I never said I was denying it. Did I ever once say that?" Adrienne gripped the wheel harder. This was good, actually. Kept her from dwelling on Clay. "I think it informs most people on a preverbal level, symbolically, maybe in dreams. But you can't convince me someone can give it a voice and ask it questions. That comes close to being as ludicrous as psychics who claim they channel twenty-thousand-year-old ent.i.ties."

"Oh, forget it." Sarah drew together with a frown. "We've had this argument before."

"It's not an argument, it's a discussion."

"Whatever it is, I'm not budging."

Good for you, Adrienne thought. One of us should be sure of herself.

She took her eyes off the highway as dawn struggled, let her gaze drift left, to the mountains. Great vast ranges of rock and earth, they looked so tame from here. Snow-drenched peaks sat wreathed in cataracts of cloudy mist like Olympian dwellings.

It was right that Clay had come this direction. Had she been forced to track him, she would have known instinctively. Deserts and mountains, the refuges of hermits ... these called to him with a voice clearer than that of any human being. He professed to be an atheist but she was not convinced he meant it, seemingly compelled to touch something so great it might destroy him. Or maybe it was because he was so inefficient at destroying himself. Either way, he was a believer in search of a higher power.

They picked their way through Fort Collins, following the sketchy directions Clay had provided; found a route that led out the other side of town, to the northwest, toward the foothills at the base of a mountain drive. The city had thinned to its barest elements, the final fringes before civilization ended.

He had called from a pay phone at an all-night diner and gas station, a rustic outpost set amid generations of pines. They found him inside at a booth, as far from the other early diners as he could get, everyone under a warm comforting miasma of pancakes and cinnamon rolls, coffee and sausage gravy.

Clay said nothing as they approached, laced his hands around a steaming cup; she wondered how many times it had been filled, if that glaze in his eyes was due to caffeine or something deeper.

Adrienne slid into the booth across from him.

Sarah hitched her mittened thumb back over her shoulder. "Why don't I head over to the counter awhile, okay?"

"That's all right," Clay said, "you can stay."

"No," Adrienne said, looked at Sarah. "Go on, it'd be best if we were alone."

She complied, and Clay raised his head, his eyebrows, in mild surprise at her take-charge mood. He looked dreadful, paler than during his final visits, with days of stubble and his hair falling toward his eyes, sweaty and matted from two nights beneath the stocking cap beside him.

"If you called me because you need a taxi," she said, "then I'm afraid I may have to leave without you. If you called me to talk ... I'm here."

It came close to an ultimatum, tough talk, but the time had come for that. It was the push of the crowbar that got the story started, interrupted by a waitress, and she took coffee only. He told her about Friday night, some pitiful encounter with Erin. She tried to listen with professional distance but things had gone too far. She pictured the two of them on that floor, too crippled to even hold each other - the most heartbreaking image she had yet a.s.sociated with him, worse even than the authoritarian abuses by his father; worse than the boy given permission to cry, just the once, for his dead baby sister and discovering he could not.

He told her of hitting the road again, of walking into Fort Collins. Of the record store. And there was remorse in his voice, his eyes; genuine remorse, held in check of course, but present, and that was something to cling to.
