"How long is that?" She pointed to the culvert.

"Twenty feet maybe. It was installed to stabilize the entrance. You can see the soil up here shifts when we get rain."

"Clear," reverberated through the metal conduit. Holden laughed. "Oscar goes down in record time. The pipe's so small he can't use the steps. He's too long from hip to knee. Coming out is what really gets to him." He pulled open the trapdoor, releasing an angry blast of warm, wet air, warmer than the air above ground. Lechuguilla maintained a temperature of about sixty-eight degrees with close to a hundred percent humidity year round. In this case it was a blessing. In a colder cave Frieda would have been at risk from hypothermia in addition to her other ills.

"M'dam." Tillman gestured toward the culvert with the pride of a maitre d' indicating a coveted window seat.

Down the drain.

In that instant Anna knew she had to confess her shortcomings, admit her fears, and get out of the hole with as much speed and grace as she could muster. Most people would be understanding. Even cavers would see that it was better to bow out than to fall apart once inside and, at best, provide the rescuers with a second casualty to evacuate or, at worst, endanger other members of the team. Not going would, in a way, be the more courageous choice. Facing up to one's failure. All this went through her mind in a calm and orderly fashion as she watched her body, possessed by demons, crab-walk over to the open culvert and begin the climb down.

Holden dropped the trapdoor. Anna felt the tremors through the palms of her hands, but she didn't hear the clang of finality. Her mind had shut down. She had no thought but of her next step, her booted toe reaching for the rung beneath, the catch of her pack on the pipe above, the circle of light inches in front of her eyes.

The culvert emptied out into a crawl space much the same as the one she'd just left. Anna chose not to think about it. Having hollered back up the culvert to let Holden know she was clear, she turned her back on the escape hatch and crawled after the faint glow of Iverson's lamp. The air in her lungs compressed until she breathed in short gasping sips. Perspiration, born cold and feeling like ice water, drenched her armpits. She wanted to weep for herself.
