"You would have been safer to keep quiet, then, till you had her whole message figured out."
He shook his head. "Unfortunately, Marta could never risk putting solid information in her diary. There's nothing in any of the four cairns that will tell us the killer's name."
"So you've told us this just to raise our blood pressure? If she could communicate all you say, she sure as hell would tell us the enemy's name." Yel‚n was clearly recovering.
"She did, but not in any of the four cairns. She knew those would be `inspected' before you ever saw them; only the subtlest clues would escape detection. What I've discovered is that there's a fifth cairn that no one, not even the murderer, knew about. That's where she wrote the clear truth."
"Even if you're right, that's fifty thousand years ago now. Whatever she left would be completely destroyed."
Wil put on his most sober expression. "I know that, Yel‚n, and Marta must have known it could be that long, too. I think she took that into account."
"So you know where it is, Wil?"
"Yes. At least to within a few kilometers. I don't want to say exactly where; I assume we have a silent partner in this conversation."
Della shrugged. "It's conceivable the enemy doesn't have direct bugs. He may have access only when certain tasks are executing."
"In any case, I suggest you keep a close watch on the airspace above all the places Marta visited. The murderer may have some guesses of his own now. We don't want to be scooped."
There was silence as Della and Yel‚n retreated into their systems. Then: "Okay, Brierson. We're set. We have heavy monitoring of the south shore, the pass Marta used through the Alps, and the whole area around Peacer Lake. I've given Della observer status on my system. She'll be running critical subsystems in parallel. If anybody starts playing games there, she should notice.
"Now. The important thing. Della is bringing in fighters from the Lagrange zones. I have a fleet I've been keeping in stasis; its next lookabout is in three hours. All together that should be enough to face down any opposition when we go treasure hunting. All you have to do is lie low for another three hours. Then tell us the cairn's location and we'll-"
Wil held up a hand. "Yes. Get your guns. But I'm going along."
"What? Okay, okay. You can come along."
"And I don't want to leave till tomorrow morning. I need a few more hours with the diary; some final things to check out."
Yel‚n opened her mouth, but no sound came. Della was more articulate. "Wil. Surely you understand the situation. We're bringing everything out to protect you. We'll be burning a normal year's worth of consumables every hour we stay on station around you. We can't do that for long; yet every minute you keep this secret, you stay at the top of someone's hit list-and we lose what little surprise we might have had. You've got to hustle."
"There are things I have to figure first. Tomorrow morning. It's the fastest I can make it. I'm sorry, Della."
Yel‚n muttered an obscenity and cut her connection. Even Della seemed startled by the abruptness of her departure. She looked back at Wil. "She's still cooperating, but she's mad as hell.... Okay. So we wait till tomorrow. But believe me, Wil. An active defense is expensive. Yel‚n and I are willing to spend most of what we have to get the killer, but waiting till tomorrow cuts the protection per unit time.... It would help if you could say how long things might drag out beyond that."
He pretended to think on the question. "We'll have the secret diary by tomorrow afternoon. If things don't blow up by then, I doubt they ever will."
"I'll be going, then." She paused. "You know, Wil, once upon a time I was a government cop. I think I was pretty good at power games. So. Advice from an old pro: Don't get in over your head."
Brierson summoned his most confident, professional look. "Everything will work out, Della."
After Della signed off, Wil went into the kitchen. He started to mix himself a drink, realized he had no business drinking just now, and scarfed some cake instead. Under all this pressure, it's just one bad habit or another, he told himself. He wandered back into the living room and looked out. In his era, letting a protected witness parade in front of a window would be insanity. It didn't matter much here, with the weapons and countermeasures the high-techs had.
The afternoon was clear, dry. He could hear dry rustling in the trees. Only a short stretch of road was visible. All the greenery didn't leave much to see. The only nice views were from the second floor. Still, he was getting fond of the place. It was a bit like the lower-class digs he and Virginia had started in.
He leaned out the window, looked straight up. The two autons were floating lower than usual. Farther up, almost lost in the haze, was something big. He tried to imagine the forces that must be piled up in the first few hundred klicks above him. He knew the firepower Della and Yel‚n admitted to. It far exceeded the combined might of all the nations in history; it was probably greater than that of any police service up to the mid-twenty-second. All that force was poised for the protection of one house, one man... more precisely, the information in one man's head. All things considered, it wasn't something he took much comfort in.
Wil reviewed the scenarios once more; what could happen in the next twenty-four hours? It would all be over by then, most likely. He was barely conscious of pacing into the kitchen, through the pantry, the laundry, the guest room, and back into the living room. He looked out the window, then repeated the traversal in reverse order. It was a habit that had not been popular with Virginia and the kids: When he was really into a case. he would wander all through the house, cogitating.
Ninety kilos of semiconscious cop lumbering down halls and through doorways was a definite safety hazard. They had threatened to hang a cowbell around his neck.
Something brought Brierson out of the depths. He looked around the laundry, trying to identify the strangeness. Then he realized: He'd been humming, and there was a silly grin on his face. He was back in his element. This was the biggest, most dangerous case of his life. But it was a case. And he finally had a handle on it. For the first time since he had been shanghaied, the doubts and dangers were ones he could deal with professionally. His smile widened. Back in the living room, he grabbed his data set and sat down. Just in case they were listening, he should pretend to do some research.
TWENTY-TWO
Yel‚n was back late that evening. "Kim Tioulang is dead."
Wil's head snapped up. Is this how it begins? "When? How?"
"Less than ten minutes ago. Three bullets in the head.... I'm sending you the details."
"Any evidence who-"
She grimaced, but by now she accepted that what she sent was not immediately part of his memory. "Nothing definite. My security at North Shore has been thin since we switched things around this afternoon. He sneaked out of the Peacer base; not even his own people noticed. It looks like he was trying to board a trans-sea shuttle." The only place that would take him was Town Korolev. "There are no witnesses. In fact, I suspect that no one was on the ground where he was shot. The slugs were dumb exploders, New Mexico five-millimeters." Normally those were pistol-fired, with a max accurate range of thirty meters; who did the killer think he was fooling? "The coincidence is too much to ignore, Brierson. You're right; the enemy must have bugs in my system."
"Yeah." For a second he wasn't listening. He was remembering the North Shore picnic, the withered man that had been Kim Tioulang. He was as tough as anyone Wil had ever met, but his wistfulness about the future had seemed real. The most ancient man in the world... and now he was dead. Why? What had he been trying to tell them? He looked up at Yel‚n "Since this afternoon, have you noticed anything special with the Peacers? Any evidence of high-tech interference?"
