“More!” Sammi said, and she joined in as well. But even their two voices combined, and redoubled by the echoes, were not enough to get the stones more than an inch off the ground. Gabriel thought of trying to get his fingers in under the stones—there was just about enough room. But that would be a good way to lose a couple of fingers, and a lousy way to get the passage open. Maybe if they had something in their rucksacks that could act as a crowbar or a lever . . . ?
“That was better,” Sammi said, when their voices had died down and the stone blocks had settled once more. “They moved.”
“Not enough,” Gabriel said.
“No, but I think singing was right—we just need to figure out the right song.”
“And how are we going to do that? There are thousands of French songs. How are we supposed to know which one was Napoleon’s favor—” Gabriel fell silent, and the room fell silent a minute later.
“What is it?” Sammi said.
He answered her only with a confident smile. He put a finger to his lips, then cleared his throat and began to sing.
La victoire en chantant
Nous ouvre la barrière
Victory, singing, opens the barrier for us . . .
La Liberté guide nos pas
Ed du Nord au Midi
. . . Liberty guides our steps; and from North to South . . .
La trompette guerrière
A sonné l’heure des combats
The war trumpet has sounded the hour of battle. With an enormous wrenching sound, the two central stones in the wall were hauled upward, vanishing into the dark roof of the cavern. The stone blocking the entryway shot up as well, leaving them with a choice of exits.
But what sort of choice was it, really? Return to the scene of the gun battle empty handed?
And never know what lay beyond this room?
Gabriel gestured for Sammi to go through the opening while he continued to sing the Chant du Départ, Napoleon’s hand-picked replacement for the Marseillaise. It hadn’t caught on as the national anthem—but by god, he’d made it the anthem of his vault back on Corsica.
Gabriel eyed the stones warily as he passed under them, still singing, but they showed no sign of being about to come down again. Once he was on the other side, he stopped, and they stayed up—until, presumably, the next unfortunate soul came along and triggered the trap.
“How in the world did you come to know that song?” Sammi said. “I thought I was the historian.”
“A good magician never reveals his secrets,” Gabriel said, and led onward.
Chapter 21
The new tunnel they were in looked much the same as the one that had led into the echo chamber. With flashlights in hand, Gabriel and Sammi ducked their heads and walked along in single file. The passage twisted and turned and at one point became so constricted that they had to crawl through on their hands and knees. They emerged on the edge of a chasm, the lip wide enough to stand on but not much more than that. Past this ledge, the ground dropped away as if cut by a knife, and there was no indication that there was another ledge anywhere on the far side. Across didn’t seem to be an option—only down.
Gabriel leaned over and shined his light toward the bottom. He estimated it was approximately thirty yards to the cavern floor. Not terrible for an experienced climber—but possibly a challenge for Sammi.
“Think you can do it?” he asked her.
“Of course. Don’t be silly.”
“All right. I’ll go first.” He removed the various tools he needed from his rucksack and laid them on the ledge. He uncoiled the rope and searched for an adequate place to anchor it. There was nothing suitable, so he took a piton with an eye and hammered it into the ledge itself. Not trusting the single piton, Gabriel grabbed two more and drove them into the rock as well. He then threaded the rope through all three eyes and tied a sturdy knot. He tugged on the rope as hard as he could to make sure the pitons would hold. Gabriel then tossed the rest of the rope over the ledge. He wasn’t sure if it was long enough to reach the bottom, but it would have to do.
Gabriel showed Sammi how to put on her harness and then fastened a Petzl stop to it with a locking carabiner. He prepared his own harness the same way. Once they were in their gear and ready to go, he gave her a quick lesson on how to use the Petzl stop as a descender.
“You control your descent by applying friction to the rope that’s threaded through here.” He showed her how to do it. “To be safe, you want to keep it pretty tight. And take your time. We’re not in a race.”
“We don’t know that,” Sammi said. “The Corsicans could come after us at any point. Or the Egyptians.”
“Only if they know the Chant du Départ.”
“The Corsicans would,” Sammi said.
“Then maybe we are in a bit of a race,” Gabriel admitted. “Still. Slower but alive is better than quick and dead.”
He took hold of the rope and threaded it into his Petzl stop. “I’ll tell you when to start down.” He then climbed over the ledge, feet first and facing the wall. He loosened the descender and slipped down several feet. Stopping, he took his flashlight and shined it all around him. There was nothing in the pit except vertical stone walls. He continued the descent and then called for Sammi to follow when he was twenty feet below the ledge. He watched as she hesitantly climbed over, dropped down and hung on the rope by her harness.
“Just hold on to the rope and use the descender.”
“All right.” She loosened the Petzl enough to inch down a few feet.
“Good,” Gabriel said.
She opened it again, wider this time—and screamed as her harness slid down the rope at a terrifying speed. Gabriel looked up at her rapidly approaching form.
“Squeeze the Petzl!” he shouted.
She managed to do so, stopping with her feet inches from Gabriel’s head.
They each took a moment to breathe.
“Sorry,” she whispered.
“You all right?”
“I think so.”
“Take all the time you need. I’m going to keep going and get a little distance between us.” He loosened his descender and rappelled down several feet. If he’d been on his own, he could have gone the whole way down in one go—he’d had plenty of experience with vertical caving and didn’t need to proceed in starts and stops. But he didn’t want to leave her hanging there alone.
When he was thirty feet below her, Gabriel called for her to continue. She carefully loosened the Petzl and moved down. She got the hang of it after a few tries and was soon rappelling with confidence. Gabriel reached the end of the rope and saw the bottom ten feet below him. He unfastened the Petzl and free fell to the floor, rolling as he landed.
“I’m down,” he called as he stood. He shined the light up at Sammi and saw her some fifty feet above him. “Take it easy, you’re doing great.”
He warned her when she got near the end of the rope and explained how to unfasten the descender and drop, legs first, to the ground. She landed beside him and sprang back up.
“You okay?” he said.
“My head still hurts,” Sammi said, “but that has nothing to do with the climb.”
“When we get out of this, I’m going to buy you the biggest bottle of aspirin you’ve ever seen.”
“Such a romantic,” Sammi said.
Their flashlights revealed an opening in the wall at the bottom of the pit. The passage beyond led into darkness too deep for their lights to make more than a small dent. Gabriel walked in and inched forward carefully, his free arm extended to one side and his feet testing the ground before placing each step.
