Coming of Age (13 page)

Tirrell had caught about one word in five of all that, but the essence made it through the jargon. “Would this method also be useful if you wanted to get a drug within range of something spread through the whole body?” he asked carefully. “Those growth hormones, say?”

“Yes,” Cam spoke up. “Dr. Jarvis has been doing that in some of his induced-hibernation work—using carriers to seek out thyroxin in the blood.”

“I didn't know that,” Somerset frowned.

She shrugged. “He said it was just an experiment, but it seemed to work pretty well.”

Growth and puberty studies, several months for work without interruption … and Colin Brimmer, a boy whose teekay was just starting its rise. Something in the pit of Tirrell's stomach began a slow tumble. “Tell me,” he said without thinking, “is it still accepted theory that the physical changes at puberty are what bring on Transition?”

The other two suddenly looked thoughtful, and Tirrell cursed his carelessness. He should have saved the question for later, when they wouldn't have been so quick to follow his line of thought. “Well,” Somerset said slowly, “it's not really that simple. Transition
does
occur sometime during puberty, but it's not a direct result of the sex hormone activity—otherwise childhood castration should eliminate it. There's a theory that even with the testes removed the adrenal cortex puts out enough testosterone to trigger Transition, but that's never been proved.” He shrugged. “But why would Matt be so secretive about working on something like that? Every endocrinologist on Tigris has taken a shot at figuring out what starts Transition. Matter of fact, he and I did some work on that four years ago.”

“What did you learn?”

“Nothing really useful. We were able to extend the B and M curves—that's brain size and metabolism rate—all the way up to Transition, but that's about all. Matt got interested in artificial hibernation after that and we put it aside.”

“I see.” Tirrell turned to Cam. “Would you go and see if you can find Dr. Jarvis's lab book for that period, please?”

“If you'd like.” She looked at Somerset, eyebrows raised.

“It'll be December and Lucember of three-oh-three and January of three-oh-four,” the other told her.

Cam nodded and left. “There's really not much in that notebook worth looking at,” Somerset told Tirrell.

“I'm mainly interested in whether the book is here or not,” the detective told him. “It seems rather odd that Dr. Jarvis would suddenly give up on something as potentially valuable as teekay research in favor of artificial hibernation.”

Somerset smiled. “You underestimate hibernation's value, Detective. For certain operations being able to slow down the patient's metabolism drastically could make the difference between life and death. And if we ever recover the space technology we had before the Lost Generation and want to go looking for other survivors of the Expansion, some form of hibernation will be vital.” He waved a hand. “Besides, as I said, Transition research is a pretty crowded field these days. Even more so than teekay work generally. You have to understand that by the time teekay first appeared on Tigris the viral DNA that triggered it had had four generations to ensconce itself in our genetic structure—
and
that all the original physiological baseline records were destroyed in the Lost Generation. What that means is that we're working essentially blind: we know what human biochemistry is like
now,
but we don't know where in the system the critical changes occurred. That makes for a pretty big target for medical science generally, but for endocrinologists the only really practical starting point is Transition.”

“And Dr. Jarvis doesn't like following the pack?”

“Not when the pack is nosing uselessly around a locked door, no. But if anyone ever comes up with the key to that door, odds are it'll be Matthew Jarvis.”

“Um,” Tirrell grunted, and for a few minutes there was silence. Somerset glanced once at his watch, and Tirrell realized with a start that it was approaching five o'clock. He'd have to end this session soon and let the others get home. He was beginning to wonder if Cam had unilaterally made that decision when she finally returned.

“There's nothing for that period in any of the file drawers,” she told Somerset. “I looked through the books for at least a year on either side of the months you gave me, and there's nothing at all on Transition B and M.”

“Uh-huh.”
Somerset looked at Tirrell. “Well, you called it, Detective, but it doesn't make any sense. Why would a blackmailer want that particular book? The B and M curves we did can be found in every book on teekay published in the past three years.”

“It
does
seem odd,” Tirrell lied. It was pretty obvious to him that Jarvis had seen something while doing the study and had hurried to quit before his coworker could also pick up on it. “Did the work involve any new techniques or anything?”

“Not really. The basic method was the one Matt came up with ten years ago. We just had to figure out a way to compensate for the wild fluctuations puberty causes in most of the useful test parameters. Matt found a statistical gimmick we could use by following a group of preteens through Transition, backtracking from their adult parameters, and—well, I won't bore you with the details. Suffice it to say that we simply came up with a statistical trick which is of no particular commercial value. It's also been published, by the way.”

Tirrell nodded, pursing his lips. “All right. One more quick question and I'll let you both go. I gather you had direct access to the preteens you did this study with. Did you also work directly with the children in the more recent tests? As opposed to letting someone else take the raw data, I mean.”

“No, we worked with them right here,” Cam said, frowning. “Why?”

“Just curious,” Tirrell shrugged. “Well, I very much appreciate your time and help in this, both of you. I hope I won't have to interrupt your work again, and I'll again ask that you keep all of this to yourselves for now.”

“You're welcome,” Somerset said as they all stood up. “Please don't hesitate to call us again if there's anything else we can do.”

“You'll be the first,” Tirrell promised. “Good night.”

“N
O, BRING THAT END
over
the other one,” Jarvis said. Sitting cross-legged on the moist ground, he indicated with his fingers the way the knot should be tied.

Carefully, Colin did as instructed, teeking the end of the rope through its last two convolutions and out through the far side of the knot. “Good,” Jarvis nodded, glancing surreptitiously at his watch. Thirty-five seconds to form the knot, subtract maybe five for hesitation and uncertainties …He would have to check that against the B and M tables when they got back to the cabin, but it looked like Colin's teekay dexterity was about where it was supposed to be. That was good; nothing drastic should be happening for a long time yet.

“Now pull this tight?” Colin asked.

Jarvis nodded. “Yes, but not too tight or you'll put too much strain on the smaller branches.”

Colin sucked his lip in concentration … and a moment later a handmade lean-to was standing proudly beneath the lowest branches of the conetree. “Yay!” the boy crowed excitedly, clapping his hands. “It worked! Can I try it?”

“Sure, go ahead.” Jarvis watched as Colin crawled carefully under the thick mesh of branches leaning at a forty-five-degree angle to the ground. A new pang slid through his chest like a knife as he once again reminded himself that Colin might someday have to use these outdoor skills for actual survival. If society overreacted—as it easily could—Colin could become an overnight outcast.

“Can I sleep here tonight, Matthew? Can I, huh?”

“I'm afraid not,” Jarvis said, smiling despite his gloomy thoughts at the sight of Colin stretched out on the leaf-and-moss rug they'd laid out under the lean-to. “Maybe in a couple of weeks we'll go on a long hike, though, and then we'll sleep out like this every night.”

“Why can't we go
now?
” Colin asked.

“Because you haven't learned enough woodlore yet,” Jarvis explained. “You need to know how to catch animals for food first, for one thing.”

“Okay.” The boy scrambled out of the lean-to, coming within an ace of bringing the whole structure down in the process. “How do you catch animals?”

“We'll work on that some other day,” Jarvis said firmly. It was already midafternoon, and he had no intention of starting such a topic without a full day ahead of them. Besides, he'd determined two days ago that he needed some information from his office, and he'd put off making that call long enough. “Right now I want you to show me you remember the knots I taught you. Then we'll go home and you can play until it's time for supper. Let's start with a half hitch; and I want you to tie it both by hand and with teekay.”

“Okay,”
Colin said with the theatrical sigh he did so well. Teeking over a piece of rope, he got busy.

It was nearly four o'clock when Jarvis finally sat down at his desk and reached for the radiophone. For a moment he paused, checking his notes, pens, and paper and confirming that Colin was visible through the window, playing happily and showing no signs that he would be bursting into the cabin at the wrong time. Picking up the handset, the scientist punched in the operator code and then his office phone number.

Cam Mbar answered on the fifth ring. “Dr. Jarvis's office.”

“This
is
a surprise,” Jarvis said lightly. “I used to sneak off work at three when
my
boss was out of town.”

“Dr. Jarvis!” Cam said, her voice unexpectedly intense. “Are you all right?”

Jarvis frowned. “Of course. Why shouldn't I be?”

“Uh …” Cam audibly struggled for control. “No reason,” she said after a few seconds, her tone now exaggeratedly casual. “I just wasn't expecting you to call.”

“I see,” Jarvis said as something prickly seemed to settle into his neck. “I need some numbers from the second to the last of our hibernation-studies notebooks. Could you get that for me?”

“Sure. You want me to bring it to you? Just tell me where—”

“No, that's okay,” he said hastily. “There's only one table I need; you can just read it over the phone.”

“Oh.” She sounded vaguely disappointed. “All right. I've got it; what do you need?”

The prickly thing on Jarvis's neck dug its barbs in a bit deeper. The cabinet where old lab books were locked wasn't within reach of any of the lab's phones … and yet Cam had found it instantly and without having to put down the handset. What would that book have been doing out at four in the afternoon?

“Dr. Jarvis?”

“Uh, yes. Um … about page eighty there are some figures on metabolism rate versus brain electrical activity …”

Cam found the place and read off the table, but Jarvis hardly heard the numbers as his hand dutifully took them down. Cam was the stereotypical unflappable scientist type—Jarvis had seen her spill hydrochloric acid down the front of her lab coat without getting as excited as she'd sounded a few minutes ago. Instinctively, his gaze flicked to Colin, who was examining a large dragonmite struggling helplessly in the boy's teekay grip. Had someone seen him putting Colin in his car back in Ridge Harbor and taken down the license plate? But surely the police would have long since found and raided his hiding place if that were the case. Wouldn't they?

His hand was sitting motionless on the desktop, and with a start he realized Cam had finished her recitation. “Thanks,” he said, hoping the silence hadn't dragged on too long. “Uh … how are things going?”

“Pretty good. We've been getting some good pituitary data the last week or two. Maybe you can come by and see it sometime soon.”

“Perhaps. Well, keep busy. I'll probably check in again later. Good-bye.” He dropped the handset into its cradle, barely hearing Cam's own good-bye as he did so.

For a long minute afterward he stared at the radiophone, gripping the arms of his chair tightly as beads of sweat gathered on his forehead. Cam's tone of voice, the notebook sitting out for no good reason, her attempt to find out where he was—it was too much to pass off as coincidence. Clearly, someone had been snooping around the lab, trying to find out what he was up to. And that someone couldn't have persuaded Cam to help him without some kind of evidence that Jarvis had indeed kidnapped Colin Brimmer.

So the police were on to him. He'd known they would be, eventually—the trail through Colin's mother Miribel was all too clear. The real question now was whether they'd had the inevitable radio direction finders running as he talked to Cam. If so, his experiment was about to come to an abrupt end. If not … well, he might still have enough time.

With an effort, he pushed himself out of the chair. The chances that the police had had everything ready were probably slim. From now on, though, use of the radiophone was out—it might, in fact, be safest to disable the instrument, lest Colin accidentally turn it on while playing inside.

Stepping to the window, Jarvis gazed out at the small boy, now standing under one of the longer branches of the nearest conetree and trying to jump high enough to catch hold of it.
What will they do to you, Colin?
he wondered.
Human society has always hated those who were different, especially those who were truly superior in some way. How will you respond to that hatred?

There was no way to answer that question—not yet, anyway. After a minute Jarvis sighed and moved away from the window. Whenever the police came, he would be ready … but right now, it was time to start cooking supper.

Hob Paxton shook his head as he again leafed through the report Tonio had flown in from Ridge Harbor and peered at the five almost-identical photos. “I wouldn't have believed it,” he said. “She really picked Jarvis's photo out of this lineup?”
