"Get as far back from the stone as you can and curl up with your back to it. Most of the chunks should bounce back out here, but some might go inward and there's no point in you getting cut."
The operation went flawlessly. Standing well back, where he would both be out of the way and able to illuminate the whole target range with his flashlight, Tirrell watched as Tonio blasted the door of Lisa's prison with a succession of melon-sized pieces of quartz. The righthand's heart was clearly in his work, and it took only a few blows before a dozen hairline cracks could be seen radiating from the impact point. The next three blows gouged out progressively larger showers of the glassy shards; and with the fourth, the top third of the stone abruptly broke off and crashed resoundingly to the floor.
The trapped girl was through the opening in an instant, landing in front of Tirrell with a shuddering sigh. "Thank you," she said, shifting her gaze to include Tonio as the righthand flew over. Taking another deep breath, she looked back at Tirrell. "I'm under arrest, aren't I?" she asked.
"For the moment, let's just say you shouldn't try to leave us," the detective said, running his eyes over her in search of injuries. "Are you all right?"
She nodded. "They didn't hurt me, unless you count scaring me to death in that hole. But I don't know what he had planned for when he got back."
Tirrell's shoulder blades tightened up. There'd been at least fifteen kids flying off with Omega earlier—more than enough to make mincemeat of two preteens and an adult. "Any idea when that'll be? Where were they going?"
"They were going to the Barona-Rand road to look for that kidnapped boy, Colin Brimmer." She dropped her eyes. "I'm sorry; if I'd known what kind of person he was, I wouldn't have helped him."
"But what does this Omega want with Colin?" Tonio asked, sounding puzzled.
"I don't know anymore," Lisa said. "He's lied about so much I don't know what's true anymore. His name's not even Omega; I saw a picture of him with the name Yerik Martel at the—"
"Yerik Martel?" Tirrell snapped.
The girl flinched. "Y-yes. I think it was him—"
"Damn, damn, damn," the detective whispered, staring through the back of the cave. Suddenly all the odd pieces of the puzzle that had never quite fit were falling into place... and the emerging picture wasn't a pretty one.
Lisa was still watching him apprehensively when he brought his eyes back to focus. "Relax," he told her, managing a smile. "I'm not mad at you. I was just startled to find out Martel was involved here." He looked at his righthand. "Does that answer your question, Tonio?"
The other was frowning. "Martel's that fagin who got away from you once, isn't he? He must be awfully hard-up if he's going to all this trouble for one kid."
"I doubt if he gives half a bill for Colin," the detective said shortly. "For the time being he's switched specialties. Weylin's told him our theory of what Jarvis is really doing out there, and that's what he's after."
"Oh, grack." Tonio's mouth was a tight line. "That's just terrific. Well, at least he doesn't know any better where to start looking than we do. I guess that's something."
"Sir?" Lisa spoke up hesitantly. "I'm sorry, but... I think I may have told him something you don't know. I—well, I saw Dr. Jarvis and Colin driving from Barona toward Rand one night last June, and I... I told Om—I mean Martel—that."
"What day in June was that?" Tirrell asked.
"The fifteenth."
Tirrell nodded grimly. "That's it, all right. Listen, Lisa, we can't let Martel get to Jarvis before we do—I can't explain, but it's vitally important. Can you take us to the spot where you saw him?"
"I think so. If it'll be faster, I could show you the spot on a map, if we can find one down in the tabernacle."
Tirrell had forgotten she could probably read maps. "As a matter of fact..." he said, digging into his pocket and glancing around. "Let's get into the light."
Moving back into the sunlit part of the cave, the detective spread his by-now crumpled map onto the gravelly floor. Squatting down beside him, Lisa touched a spot some sixty-five to seventy kilometers west of Barona. "It was about here, I think," she said. "I also told him about these two spots—I saw them marked in your book." She pointed to two of the rockmud areas straddling the road further on toward Rand.
Tirrell felt his stomach tighten. If Lisa's placement of the meeting was correct, there were less than a dozen areas left where Jarvis could be... and Martel had two of them. "Damn. We've got to get after him right away."
"Wait a second," Lisa said, teeking the map back down as he started to refold it. "I didn't remember when I was talking to Martel—I saw Dr. Jarvis's car turn off the road to the right just after I left him."
"You did?" Frowning, Tirrell peered at the map again. The nearest road marked was at least a kilometer from the place Lisa had indicated. Either her estimate was off or Jarvis had taken something more informal then a real road. Either way—"I guess you're going to have to show us the actual place, after all." He studied her face, noting the fatigue there. "You feel up to it?"
"Sure," she said, straightening her back a bit.
"Good." Tirrell folded up the map and stood up. "There was a well-stocked pantry in the big tent; we'll grab some food and head straight out, if you don't mind eating while we fly."
Both preteens nodded. "We still going to stop by Plat City and report this place to them?" Tonio asked.
"I don't think so," Tirrell said slowly. "I'm beginning to think it's almost certain that Martel's suborned one or more righthands there like he did Weylin, and I'd rather not tip them off that we've found his base."
"Why is it certain? Because Plat City's closer than Barona?"
"No. Because of this." Tirrell waved his hand to encompass the huge cave.
Lisa glanced up. "This? But this is just where he's going to build his Temple of Truth."
"Temple of Truth, eh? I should have figured Martel to come up with something cute. I suppose he has his followers dump the rocks a good distance away; say, by a river somewhere?"
Lisa blinked. "There is a river in the valley where the rocks are taken. How did you know?"
"Because the rocks are what he's really after here—the rocks and the free labor to dig them out." Tirrell gestured. "My guess is that he's taken a couple million bills worth of gold out of here already, and the vein's probably got at least that much still in it."
"Gold?" Tonio looked stunned. "You said it was quartz."
"Most of it is," Tirrell nodded. "But if you look at the walls closely you can see bits of gold glittering there. How Martel stumbled on a vein this rich I don't know, but the point is that unless he takes the gold down the far side of the Tessellate Mountains, he has to run it through the assay office in either Plat City or Rand, and he's too cautious not to have installed at least one listening ear in each city's police department. That's how he got away from us in Ridge Harbor, and he's not likely to change a winning system." He glanced at his watch. "We'd better get moving—Martel's already a good hour and a half ahead of us, and even if he starts with the wrong areas he's got fifteen or more airborne searchers to our one."
"Our two," Lisa corrected, her voice quiet but determined.
"Forget it," Tirrell told her. "As soon as you've shown us where Jarvis turned off the main road, you're going to go to Barona and turn yourself in to the police as a material witness."
"But I want to help you," she said. "I mean, this whole mess is my fault. Again." Her eyes were glistening with moisture, and Tirrell sensed she was fighting back tears. "I got a friend in trouble who was just doing something I asked him to—and now I've made things bad for you in trying to help him." She turned half away, biting her lip.
