"Guess," Anna demanded, unable to help herself.

"A day. Maybe two."

Anna's heart shriveled up till it felt the size of a wizened lemon. "Twenty-four-hour days or eight-hour days?"

"Could go either way," he replied unhelpfully.

Holden took over. "We got nothing to dig with and the best we can do to help is get out of the way. They're going to be pushing out on this slope, and it'll slide again before they're done. We've all put in close to a nineteen-hour day. Everybody's shot. Till we've rested we're just accidents waiting to happen. We'll set up a base of operations back at the other end of this hole. We've got beaucoup water. Rapunzel goes down forever. This cave's got enough air to be considered a wind tunnel in some parts of the world, and we've got food. Lechuguilla's warm and dry. All we've got to do is get comfy and wait for the cavalry to arrive. My guess is old Oscar here is being conservative. We only need wiggle room, not the Holland Tunnel. We'll be out of here in eight or ten hours. Let's go spread the good word."

Though he'd chosen to be brave, macho, noble, and all the things that Anna and, she was sure, the others, had hoped he would be, Tillman remained a cautious man. Because of his ankle he tied himself between Oscar and Brent, the strongest of those in their truncated group. It could have been argued that McCarty was sturdier than Iverson, but he hadn't recovered from the trauma of the avalanche or Frieda's death-whatever demons stopped his voice and drained the blood from his lips.

Consumed by an all-encompassing fatigue, Anna was unable to take much interest in McCarty's well-being. Body, mind, and spirit were exhausted. The ache in her arm and her fear of falling kept her awake. The lure of the lamp kept her moving forward. She'd come to believe there were no flat level places in all of the inner space of Lechuguilla. The "trail" they'd been calling the goat track was like the dotted line on a cartographer's drawing; it existed only in their minds. Reality was a stretch of rock that could be navigated only by borrowing from the traveling techniques of spiders, monkeys, starfish, and weasels.

On the careful trek back, McCarty was in line behind Anna, taking up the last position. "Sondra?" he said with the startled intonation of a man remembering a package left behind in a taxicab. He had to say it a second time before the import penetrated Anna's haze of self-absorption.

"Sondra?" she echoed stupidly, and ceased all movement to summon the energy required to process the idea. "Zeddie!" she hollered when the thought had percolated through the layers of dulled emotion.

"Yeah?" Zeddie called back. Anna could just see her, down on all fours like a muddy St. Bernard, fifteen or twenty feet ahead.

"Is Sondra back with Curt?"

A moment's silence followed, then the almost inevitable response: "Wasn't she with you?"

Anna swiveled her head to see if the message had reached the doctor. It was the only part of her anatomy she felt she could disturb without danger of dislodging her corpus from the rock face. With the poor light and the distance, she could scarcely read his reaction, but it looked as if as much guilt as worry. Maybe he realized how late in coming was this concern for his missing spouse. Anna studied him an instant longer, trying to see if relief mixed with concern on his face. If it did, she missed it.

"She told me she was going to rotate out," Anna remembered.

Now the doctor did look relieved, and Anna mirrored the sentiment. Intrigue in addition to all else that had happened might have proved to be the proverbial straw.

Camp was luxurious by caving standards: there was a fairly flat spot for everyone to lie down on. At Holden's insistence, food was eaten. Most were so tired they would have forgone the meal to avoid the effort of lifting the spoon from container to mouth. Understanding the need to fuel the body, Anna ate mechanically. The disappearance of Sondra was hashed and rehashed. The four cavers who had taken up the rear position on the Pigtail had spoken to her early on during the rigging but hadn't seen her since the actual haul began. Anna dutifully repeated her hopeful tale of Sondra's opting to rotate out. No one had seen her going ahead with the others, but such was the crush of cavers and the business of the traverse they might easily have missed her. She'd not told her husband of her plans. None but the four newcomers seemed to think that unusual. Anna wasn't the only one who'd noted the relationship between Peter and Sondra was strained.

Consensus was that Sondra had gone out. Either that or she lay under the rock and dirt of the slide. Despite the slimness of this possibility, Anna knew Holden would have spent the night digging but for the fact that by the time Peter McCarty had mentioned she was missing it was too late, she'd have been long dead. Holden wasn't one to risk the living for the dead no matter how good it might look on paper.

Chewing, swallowing, drinking warm water, it occurred to Anna that Peter might have waited on purpose. A rock slide would be a convenient end to an inconvenient marriage. Anna had no idea what power Sondra thought she had to jerk her husband's medical license, but if it was true and half an hour's malicious silence could remove the threat for all time…

Anna's punch-drunk brain fumbled at the thought for a while, then let it go. Odds were against it. At any rate it would be unprovable.

Oscar and Holden did a commendable job with their pep talks. Oscar's was filtered through fatigue and Holden's a near-crippling sense of guilt, but they served their purpose. The team was given hope and cohesion. Lisa, the long-braided caver who had been trapped with the core group, was a practicing Buddhist. She said a prayer for Frieda that Anna was too tired to follow, but she appreciated the gesture.

One by one they made the creeping journey from their bivouac to the mouth of the Pigtail where there was a good "squatting rock" and they could perform their evening ablutions. Limited space precluded both a ladies' room and a men's, so an empty water bottle was set in the trail. If the bottle was upright, the loo was available, if on its side, occupado.

Throughout the bustling and munching, the coming and going, Holden and Oscar sat huddled in conversation. If asked a direct question or detecting a need of a team member, they would break from their tête-à-tête, only to return to it the moment they were no longer wanted. They spoke so quietly Anna couldn't discern individual words. She didn't have to. She knew as surely as if she sat with them that they were rigging and rerigging the traverse, mentally stalking around the anchor boulder, asking each other if they could have seen something that signaled instability, if they'd missed a tell-tale sign that might have saved Frieda's life. Unless cause and effect were established, this was a conversation Holden Tillman was going to have with himself for many years to come.

Finally, tucked in close as sardines in a can, the cavers bedded down. Anna was sandwiched between Curt Schatz and Lisa. Where she would have expected a deepening of claustrophobia, she found comfort. Lamps were extinguished. Before the heavy night of the underground could oppress, Zeddie began to sing. Her rich alto reverberated from the stone and filled all the cracks and crevices with humanity, pushing back the unforgiving dark. A truth Anna had long suspected was ratified: we are one another's angels. No unearthly sound could have been so glorious.

"Life is like a mountain railroad with an engineer that's brave. We must make the run successful from the cradle to the grave," soared through their miserable night, powered by notes of youth, tones of raw faith in the inherent goodness of existence. Old-time gospel had a healing power bloodless intellectual faith could not lay claim to.
