He briefly wondered how long ago she had had Murder Mountain ready to go. And was she somewhere nearby, detonating these charges? Was she somehow watching them, knowing exactly when to set off each one? And then he had no more time to wonder, as everyone looked at him.

“What now?” said Chapman breathlessly, her face, like all the others’, caked with grime from the dust and smoke.

Stone looked upward as another charge detonated, though not nearby. But more of the facility collapsed and the mountain gave another shudder.

Then the lights went completely out, plunging them into darkness.

Stone, Finn and Knox immediately powered up their NV goggles. Stone took Annabelle’s hand, Knox took Caleb’s and Finn clamped his hand around Chapman’s wrist.

“Follow me,” said Stone.

There was one more way out of here. And as far as Stone knew, he was the only person who had ever discovered it. This was their last chance.

He was very conscious of the fact t

hat he had no idea where the next charge Friedman had placed would detonate. She had no reason to allow them to leave here alive, where they could tell people the truth. Each step they took could truly be their—

Annabelle screamed.

CHAPTER 101

JOE KNOX DISAPPEARED UNDER A PILE of rubble as a charge detonating fifty feet away collapsed the section of wall next to him. The others instantly began digging the man out. Stone was on his knees pitching chunks of debris off his friend. His fingers and arms bloodied, the sweat stinging his eyes, he frantically worked in the dark to free Knox. Finally, his fingers touched flesh. In two more minutes they had uncovered the man completely.

Knox was breathing, but unconscious.

Stone started to lift him up, but Finn said, “Let me do that.”

He hoisted the two-hundred-pound Knox over his shoulder.

“The only other way out is up, Harry,” said Stone.

Finn nodded, a grim look on his face. “Just lead the way.”

Stone took the length of rope from Knox’s knapsack that the man had used to help rescue Caleb from the tank of sludge. Each person looped the rope around their middle and then passed it on.

“Let’s move,” said Stone.

He prayed that Friedman had not figured out the third exit from Murder Mountain, as he had done all those years ago. He led the group across the main hall and down to the other end. Stopping in front of what looked like a sheer wall of metal, he ran his fingers up and down its surface. It was cold to the touch, still strong, seemingly impenetrable. Rivets ran up one side of the panel and down the other. Another explosion shook the building. Dirt and dust tumbled down on them from the weakening ceiling.

He pressed on one spot and the wall gave way. He slid the metal out of the way and a set of crude rock stairs was revealed. They went through the opening and headed up.

Stone wondered how long it would take for the authorities to realize what was happening. Some local would report the explosions. This would be relayed to the sheriff’s department or whatever police was up here. They would send someone, probably a single officer, and that person would have no idea what they were faced with. Calls would be made. At some point, after a lengthy interval, the CIA would hear of it. They would send a team up here helter-skelter.

But what would they find?

They would find exactly what Friedman wanted them to find. Dead Russian muscle, possibly tied to the drug cartels. And a nanobot research facility where long ago the CIA had trained its assassins. That would hit the national and global news pipelines like a nuclear warhead.

And they will find us, thought Stone. They’ll find us dead.

But how would she accomplish that last part? The explosions might seal them in here, but they could conceivably survive until rescuers arrived. They had some food, some water. There might be supplies here they could use.

She would have thought of that. There has to be something else.

They kept moving. When Finn grew tired, Stone hefted Knox over his shoulder and carried him for as long as he could. Then Finn swapped back. But as the route took them upwards, it became harder and harder to manage. Yet they kept going.

Chunks of rock now dropped from above with each detonation, since they were in parts of the facility that had never been built out, where the mountain had been left untouched.

Annabelle gasped, “Where are we headed?”

Stone pointed up. “Not much farther.”

“Is it on top of the mountain?”

“Close to it.”

“Is there a way down?”

Stone didn’t answer right away. Actually he didn’t have an answer. He had used this exit before, finding it mostly by accident one night when he couldn’t sleep. But he’d never gone down the mountain. He’d just looked at the stars, had a few moments of peace before heading back and taking up his training once more. So he didn’t know if there was a way down the mountain. But there had to be. He would find one.

They struggled on.

Annabelle was the first to see it.

“Light!” she exclaimed.

They rushed forward, encouraged by perhaps the end to their journey.

It was a natural cleft in the mountaintop that decades ago Stone had enlarged and then covered with materials he had smuggled up from the facility below. The cracks of light did not lie. The dawn had broken
