Sam reached back until he felt Remi’s outstretched hand, grabbed the carabiner, and pulled the coil up to him. He tied first a slipknot into the loose end, followed by a stopper knot; to this, for weight, he clipped the carabiner. He maneuvered his body until his arms were free of the opening, then tossed the line across the pit, aiming for one of the larger stalagmites a few feet below the opposite tunnel opening. He missed, retrieved the rope, tried again, this time laying the slipknot over the tip of the protrusion. He jiggled the line until the knot slid down to the base of the stalagmite, then cinched the knot tight.
“Care to help me with a stress test?” Sam asked Remi. “On three, pull with everything you’ve got. One . . . two . . . three!”
Together, they heaved on the rope, doing their best to rip the stalagmite from the wall. It held steady. “I think we’re okay,” Sam said. “Can you find a crack in the wall and—”
“I’m looking . . . Found one.”
Remi slid a spring-loaded cam into the crack and fed the rope through it, then through a ratchet carabiner. “Take up the slack.”
Sam did so, heaving on the rope as Remi slid the carabiner up to the cam until the line was as taut. Sam gave it a test pluck. “Looks good.”
Remi said, “I suppose it goes unsaid—”
“What, be careful?”
“Yes.”
“It does. But it’s nice to hear anyway.”
“Luck.”
Sam wrapped both hands around the rope and shimmied forward, slowly transferring his weight onto the line. “How’s the cam look?” he asked.
“Steady.”
Sam took a steadying breath, then pulled his lower legs free of the crawl space. He dangled in the air, not daring to move, gauging the sag in the rope and listening for the sound of cracking rock, until ten seconds had passed. He then pulled his legs up, hooked his ankles over the line, and began inching across the pit.
“Holding steady on this end,” Remi called when Sam reached the halfway point.
Sam reached the opposite wall, transferred first one hand, then the other, to the stalagmite, then swung his legs up and braced his right heel against another protrusion. Testing his weight as he went, he contorted his body until he was sitting perched atop the stalagmite. He took a moment to catch his breath, then slowly stood up until he was level with the opening. A quick boost with his hands and a shove off the stalagmite, and he was inside the crawl space.
“Be right back,” he called to Remi, then scrabbled inside. He was back thirty seconds later. “Looks good. It widens out farther on.”
“On my way,” Remi answered.
In two minutes she was across, and Sam was pulling her into the opening. They lay still together for a few moments, enjoying the feeling of solid rock beneath them.
“This reminds me a lot of our third date,” Remi said.
“Fourth,” Sam corrected her. “The third date was horseback riding. The fourth was the rock climbing.”
Remi smiled, kissed him on the cheek. “And they say guys don’t remember those things.”
“Who’s they?”
“They who haven’t met you.” Remi shone her headlamp around. “Any sign of booby traps?”
“Not yet. We’ll keep a sharp eye, but if your estimate on the age of that spear is accurate, I doubt any trip mechanisms would still be working.”
“Famous last words.”
“You have my permission to put it on my tombstone. Come on.”
Sam started crawling, with Remi right behind him. As Sam had promised, a few seconds later the crawl space opened into a kidney-shaped alcove roughly twenty feet wide and five feet tall. In the opposite wall were three vertical clefts, each no wider than eighteen inches.
They stood up and stoop-walked to the first cleft. Sam shone his headlamp inside. “Dead end,” he said. Remi checked the next: another dead end. The third cleft, while deeper than its neighbors, also petered out a half dozen paces inside.
“Well, that was anticlimactic,” Sam said.
