“Do you recognize the language?” Sam asked.

“No.”

“This is remarkable,” Sam said. “Even with modern woodworking tools it takes incredible skill to create something like this.”

He rapped on the side with his knuckles and got a solid thud in return. “Doesn’t sound hollow.” Gently he rocked the chest from side to side. From within came a faint rattling sound. “But it is. Fairly light too. I don’t see any other markings? You?”

Remi leaned down and from side to side, examining it. She shook her head. “Bottom?” Sam tipped it. Remi checked, then said, “Nothing there, either.”

“Somebody went to a lot of trouble to build this,” said Sam, “and it looks like our friend here was prepared to give his life to protect it.”

“It may be more than that,” Remi added. “Unless we’ve stumbled onto the mother of all coincidences, I think we may have found what Lewis King was looking for.”

“If so, how did he miss this? He was so close.”

“If he didn’t make it across the pit,” Remi replied, “could he have survived?”

“Only one person knows the answer to that.”

They turned their attention to documenting the contents of the cave. Not knowing how soon they would return, and unable to take with them but a fraction of the artifacts, they would have to rely on digital photographs, drawings, and notes. Luckily, Remi’s background and training made her well equipped to do just this. After two hours of painstaking work, she proclaimed the job done.

“Wait,” Remi said, then knelt beside the shield.

Sam joined her. “What is it?”

“These scratches . . . the light caught them. I think . . .” She leaned over, took a deep breath, and blew on the shield’s leather surface. An accumulation of rotted leather dust scattered.

“Not a scratch,” Sam observed, and blew clear some more dust, then again and again until the shield’s surface was exposed.

As Remi had suspected, the scratches were in fact an etching burned into the leather itself.

“Is that a dragon?” Remi asked.

“Or a dinosaur. Probably his crest or that of his unit,” Sam guessed.

Remi took a couple dozen shots of the etching, and they stood up. “That’ll do it,” she said. “What about the chest?”

“We have to take it. My gut tells me it was why our friend had barricaded himself in here. Whatever’s inside was something he thought worth dying for.”

“I agree.”

It took only a few minutes for Sam to jury-rig a web of straps that allowed him to piggyback the chest on his own pack. They took a last look around the cave, nodded a good-bye to the skeleton, and departed.

In the lead, Sam crawled up to the lip of the pit and peeked over. “Now, that’s a problem.”

“Care to be more specific?” Remi said.

“The rope’s given way at the other end. It’s dangling into the pit.”

“Can you rig a-”

“Not with any confidence. We’re above the other opening. At this angle, if I try to cinch the slipknot into place, it’ll just slide off. There’d be no way to take up the slack.”

“That leaves only one option, then.”

Sam nodded. “Down.”

It took but a minute for Sam to secure himself to the line. As he did, Remi set up a second belay point by hammering a piton into a crack just below the opening. Once it was set, Sam began a slow rappel, walking himself over and around the jutting stalagmites, while Remi kept watch from above, occasionally telling him to pause and adjust position to minimize the rope chafing on the protrusions.

After two minutes of careful work, he stopped. “I’ve reached the other cam. Good news: the cam tore free.”

If the rope had parted, they would have had to splice their remaining line onto the loose end. Now he had sixty feet of line beneath him. Whether that would be enough to reach the bottom was still an unknown. If what awaited them was the icy cold water of the Bagmati River, they would have fifteen minutes at most to find a way out before succumbing to hypothermia.

“I’ll take that as a good omen,” replied Remi.

Foot by foot, careful step by careful step, Sam kept descending, his headlamp receding into a small rectangle of light.

“I can’t see you anymore,” Remi called.

“Don’t worry. If I fall, I’ll be sure to give out an appropriately terrified scream.”

“I’ve never heard you scream in your life, Fargo.”

“And, cross fingers, you won’t this time.”

“How’re the walls?”

“More of the-Whoa!”

“What?”

No response.

“Sam!”

“I’m okay. Just lost my footing for a second. The walls are getting icy. Must be mist from the water below.”

“How bad?”

“Just a thin coating on the walls. Can’t trust any of the stalagmites, though.”

“Come back up. We’ll figure out another way.”

“I’m continuing on. I’ve got another thirty feet of rope to play with.”

Two minutes passed. Sam’s headlamp was a mere pinpoint now, jostling back and forth in the pit’s darkness as he maneuvered around the stalagmites.

Suddenly, there came the sound of shattering ice. Sam’s headlamp began spinning, winking up at Remi like a strobe light. Before she could open her mouth to call to him, Sam shouted, “I’m okay. Upside down but okay.”

“More description, if you please!”

“Got turned around in my harness and flipped. Good news, though: I’m staring at the water. It’s about ten feet below my head.”

“I hear a ‘but’ coming.”

“The current’s fast-three knots at least-and it looks deep. Waist-high, probably.”

Though three knots was slower than a fast walking pace, the depth and temperature of the water multiplied the hazard. Not only would it take only one minor misstep to be swept away but the exertion it would take to stay upright would speed up the hypothermia process.

“Come back up,” Remi said. “No arguments.”

“Agreed. Give me a second to . . . Hold on.”

From the darkness came more cracking of ice, followed by splashes.

“Talk to me, Fargo.”

“Give me a second.”

Another thirty seconds of cracking, then Sam’s voice: “Side tunnel!”

After ten minutes of detailed work, Sam shouted, “It’s good-sized. Almost tall enough to stand in. I’m going in. Give me a minute to set up a belay.” If Remi went into the subterranean river, this measure would give Sam a fighting chance to reel her back in-provided there weren’t rocks downriver ready to bash Remi into pulp.

Once this was done and Sam was braced and ready to take slack, Remi started her descent. Lighter and a bit more agile than her husband, she covered the distance in less time, pausing only to allow Sam time to take up slack through the piton’s belay point.

At last she descended into view and stopped even with the side tunnel’s entrance. Headlamps shining into one another’s faces, they shared a relieved smile.

“Fancy meeting you here,” Sam said.

“Damn!”

“What?”

“I had a mental bet you were going to go with ‘What’s a nice girl like you doing in a nearly bottomless pit like this?’”

Sam laughed. “Okay, you’re going to have to go Superman in your rig and push off the opposite wall. I’ll catch you.”

Remi took a few moments to catch her breath and then made the appropriate adjustments to her harness until she was hanging perpendicular in the pit. Flexing her body, she slowly built up a swing until she could toe-push off the opposite wall. Three more of these allowed her to fully coil her legs and push off. Arms extended, she swung forward, hands grasping. The side wall rushed toward her face. She ducked her head. Her arms slipped into the tunnel. Sam’s hands clamped on hers, and she jolted to a stop.

“Got you!” Sam said. “Wrap both hands around my left wrist.”

She did, and Sam used his right arm to slowly release some slack in the rope so Remi could climb up his arm. Once her torso was inside the tunnel, Sam began back-crawling until her knees were also inside. He fell back and let out a relieved sigh.
