Chapter 65: What the Stone Holds

Carrick remained beside the second board. On Leo’s rough map, Rafael had added Jonah’s position to the cluster.

Leo looked at Jonah’s new position on the map, then at the thermometer Ruth still held.

"One more reading here. One on the ordinary shelf. After that, I need you both outside."

Carrick glanced at him. "What do you mean?"

"The next part uses classified Crown methods. You and Ruth wait by the entrance until I call you back."

Carrick looked over the shelf. "And you’re not damaging anything?"

"No."

Carrick nodded. "All right. If that changes, you ask me first."

Ruth looked less pleased, but she helped finish the comparison before leaving. Rafael recorded the two temperatures. Armin crouched by the wall and noted the tide against the lower rock beside the nearest seep. He also marked which surfaces were wet enough to shine under the lantern.

Ruth gathered the medical case. "We’ll be by the first turn," Carrick said.

Leo shook his head. "Farther. Past the bend."

Carrick glanced once toward the shelf, then walked out with Ruth. They waited until both sets of footsteps had faded behind the bend, leaving only the surf in the cavern.

Leo pointed to a dry patch several paces from Jonah’s position. "Start there."

Severin stripped off his right glove and pressed his palm flat to the stone. He focused on the blind left eye beneath its covering until a faint green glow showed through the cloth.

Months ago, even a small pull had demanded all his concentration. Now he kept it no wider than his hand and drew heat from the rock until cold bit into his skin. Dampness around his fingers paled with a trace of frost.

Armin started his watch. After several seconds Leo said, "Enough."

Severin cut the pull and lifted his hand.

Armin set the glass thermometer against the cooled patch and folded cloth over it exactly as Ruth had done. Rafael watched the line in the glass, wrote the reading, then waited while Armin called the intervals from his watch.

The stone crept back toward the cavern’s temperature at an unremarkable rate.

"Good. Jonah’s position."

Severin crossed to the second board. He put his palm against the stone where Carrick had said Jonah spent almost all of his worst hours.

"Same amount?" Rafael asked.

"As close as I can."

"That will do."

Severin drew again. The cold formed faster under his palm this time, though he could not tell whether that came from the stone or from his own improving control. He kept the pull as narrow as before until Armin called the same interval, then cut it.

Armin moved the thermometer over. The reading fell, and they waited.

Severin crouched with his forearms on his knees. Part of him wanted to try the patch again and pull harder. If the stone could push back toward its old temperature, he wanted to know how far it could be forced before it failed.

That would be a different test, and forcing it farther now would only spoil the comparison. He kept his hand off the stone.

Armin checked his watch. Rafael leaned closer to the glass.

"That’s moving," Rafael said.

Leo stepped over. "Compared with the control?"

Rafael flipped back to the earlier line. "Faster."

They waited another interval.

The control patch was still well below where it had begun. Jonah’s section had already climbed much closer to the narrow range they had measured before Severin touched it.

Severin looked at Leo. "So it doesn’t like staying cold."

"Careful."

"I said doesn’t like. I didn’t say it was complaining."

Armin gave a quiet snort and moved toward the wall.

Leo ignored both of them. "Good. Leave it. We’ve got what we need."

Severin put his glove back on and rubbed thumb against forefinger. His fingers answered cleanly, without the lag that followed harder use. He could repeat the test if they needed him to.

Armin had already begun tracing the visible seepage. He followed a thin wet line down from a crack, checked the stone beneath it, then moved to the next damp patch. He compared those against Rafael’s map and crouched at the lower edge of the shelf where seawater reached on a higher tide.

After several minutes he stood and tapped one section of the map. "The visible seep could explain this corner. Not Jonah’s position."

"Hidden water?" Rafael asked.

"Possible. Could be a deeper crack or a channel behind the wall. Warmer rock farther in too. I can’t see through stone."

Leo looked toward the pale-veined section. "I might get closer."

Leo removed his left glove. He focused on the mark across the back of his hand until it glowed green, then set his palm against the ordinary comparison rock.

For a few seconds nothing happened that Severin could see. Leo shifted the heel of his hand, then his fingers.

"Normal?" Rafael asked.

"Just stone," Leo said. "Damp in places, with a small crack running through it. Nothing useful."

He crossed to the inner shelf and pressed his left hand against the pale-veined section nearest Jonah’s position. This time he stayed there longer. His fingers flexed once against the surface, then again.

"What?" Severin asked.

Leo did not answer. He moved his palm half a handspan to the side and repeated the contact. The smallest finger on his marked hand began to shake, and Leo pulled away.

Rafael had his pencil ready. "What did you get?"

"That came back wrong."

"Meaning?"

Leo rubbed his thumb across the side of his left index finger. "One path dies too quickly. Another carries farther than this section of stone should let it."

Severin looked at the wall. "Something behind it?"

"Maybe."

Leo touched a point farther along the pale deposit and held contact for only a few seconds before withdrawing.

"Different again," he said, and Rafael marked the location.

They continued along the shelf, but not for long. Leo tested only enough points to establish that the strange response did not match the visible pale lines cleanly. One pale section gave nearly the ordinary stone response. A darker patch beyond it gave the layered response again.

By the fourth abnormal point, Leo’s left fingers had developed a fine tremor.

"That’s enough," Severin said.

Leo flexed the hand and put his glove back on. "Agreed."

Rafael crouched over the map. He had been adding symbols as they worked. The stabilization cases clustered near the thermal anomaly from earlier. Severin’s faster recovery test sat inside the same broad region.

Leo’s strange resonance crossed part of it, then wandered beyond it toward stone that looked ordinary. Armin’s visible seepage cut through only one edge.

Rafael turned the page so they could all see it.

"The overlap is real," he said. "But none of these follows the others exactly."

Severin pointed at the pale deposits. "And those don’t match much of anything."

"Not reliably."

Rafael traced the pale line with the blunt end of his pencil, then stopped where the heat marks continued without it.

"If the deposit were causing all of it, I’d expect the lines to match better."

"So would I," Leo said.

Severin studied the map again. The cave had looked simpler before they started measuring it.

Armin leaned over Rafael’s shoulder. "Water still gets to keep some of the blame."

"Some," Leo said.

Rafael tapped the map with the pencil. "A sample would tell us what it’s made of."

"Not yet."

Severin looked at Leo. "You think breaking a bit off could change it?"

"We don’t know what we’d be breaking." Leo glanced toward the cavern entrance. "This place keeps people alive. We leave it alone until we know what we’re cutting into."

Leo called Carrick and Ruth back. Ruth appeared first around the bend, carrying the medical case against her hip, with Carrick close behind.

"Well?" Carrick asked.

Leo kept the answer plain. "Different parts of the shelf behave differently. The ordinary readings didn’t show all of it."

"Dangerous?"

"We don’t know."

"Does that change what we do?" Carrick asked.

"No. Same safeguards for now."

Carrick looked toward Jonah’s section rather than at Leo. "Then the position matters more than I thought."

Carrick stepped closer to the numbered positions on Rafael’s page. "If one part of this shelf is less safe than another, I need to know before I put another patient on it."

"As soon as we have something solid, you’ll know," Leo said.

Carrick nodded.

"Then we should record exact positions from now on," Rafael said.

Ruth adjusted the medical case against her hip. "We can number the working positions."

Carrick looked at her.

"Not the stone," she said. "Small tags on the boards. One here, one farther out, then we record exactly where the stretcher sits and how long the patient stays."

Rafael nodded. "That would be better than ’inner shelf.’"

"I know," Carrick said. "We should have done it years ago."

Ruth opened her mouth to answer.

A horn sounded outside. The note carried in from the cove, hard and close enough to cut through the surf.

Ruth turned toward the entrance. A second call followed.

Carrick was already moving. "They’re back."

They reached the cavern mouth as a voice shouted from the cove.

"Doctor!"

Ruth set the medical case down on the wet rock and opened it. "How bad?"

The answer came from near the water, broken by the surf.

"We can’t move him far!"

Carrick looked toward the route up the cleft, then back at Jonah’s board.

He turned into the cavern. "Ruth, blankets. Clear Jonah’s board."

She was already moving. Carrick carried the open medical case back to the inner shelf.

"Bring him in here."
