Sam seemed to understand. He knelt beside Pachacutec and touched the king’s robe. “Sapa Inca,” he said, bowing his head. “The temple saved my life, as it once saved yours. Use it again.”
Pachacutec stopped rocking, but his head still hung in sorrow. “My people gone.” He raised his face toward Sam and the others. “Maybe it be right. We do not belong in your world.”
“No, heal yourself. Let me show you our world.”
Henry stepped forward, placing a hand on Sam’s shoulder, adding his support. “There is much you could share, Inca Pachacutec. So much you can teach us.”
Pachacutec pushed slowly to his feet and faced Henry. He reached a hand to the professor’s cheek and traced a wrinkle. He then dropped his arm and turned away. “Your face be old. But not as old as my heart.” He stared into the temple, his face shining. “Inti now leads my people to
Henry stared over the king’s shoulder to Sam. What could they say? The man had lost his entire tribe.
Tears ran down Pachacutec’s cheeks as he slid a gold dagger from inside his robe. “I go to join my people.”
Henry reached toward the Sapa Inca. “No!” But he was too late.
Pachacutec plunged the dagger into his breast, bending over the blade like a clenched fist. Then he relaxed; a sigh of relief escaped his throat. He slowly straightened, and his fingers fell away from the blade’s hilt.
Henry gasped, stumbling back, as flames jetted out from around the dagger impaled in the king’s chest. “What the hell…?”
Pachacutec stumbled into the temple’s chamber. “I go to Inti.”
“Spontaneous combustion,” Sam whispered, stunned. “Like the cavern beasts.”
Maggie nodded. “His body’s the same as the creatures’.”
“What’s happening?” Henry asked, staring at the flames.
Maggie explained hurriedly, “The gold sets off some chain reaction.” She pointed to Pachacutec. Flames now wound out from the dagger and coursed over his torso. “Self-immolation.”
Henry suddenly recalled Joan’s urgent message to him in the helicopter. She had warned him of a way to destroy Substance Z. The gift stolen by Prometheus.
Turning, Henry saw Pachacutec fall to his knees, his arms lifted. Flames climbed his raised limbs.
Henry grabbed Sam and Maggie and shoved them toward the tunnel’s exit. “Run!” he yelled. He kicked the kneeling guard. “Go!”
“What? Why?” Sam asked.
“No time!” Henry herded them all onward. Denal and Norman ran ahead, while Henry and Maggie helped Sam on his wobbly legs. As they fled, Henry recalled Joan’s final warning:
Her words proved too true. As they reached the tunnel’s end, a massive explosion rocked the ground under their feet. A blast of superheated air rocketed the entire group down the path, tumbling, bruising. The passage behind them coughed out smoke and debris.
“On your feet!” Henry called as he bumped to a stop. “Keep going!”
The group obeyed with groaned complaints, limping and racing onward. The trail continued to tremble under their heels. “Don’t stop!” Henry called.
Boulders crashed down from the volcanic heights. The shaking in the ground grew even worse. Below, hundreds of parrots screeched and flew out of the jungle canopy.
As Henry reached the escarpment below the cliffs, he risked a glance back up. A monstrous crack in the rock face trailed from the tunnel straight up the side of the cone.
Sam leaned on Maggie, both catching their breath. The others hovered nearby. Sam’s eyes suddenly grew wide. “Oh, God!” he yelled. “Look!” He pointed across the valley.
Henry stared. The original steam vents had become spewing geysers of scalding water. New cracks appeared throughout the valley, belching more foggy steam and water into the sky. One section of the volcanic cone fell away with a grinding roar. “It’s coming apart!” Henry realized.
Maggie pointed behind them, toward the volcanic peak to the south. Black smoke billowed skyward. The scent of sulfur and burning rock filled the valley.
Sam straightened. “The explosion must have triggered a fault. A chain reaction. Hurry! To the helicopter!”
Norman chimed in with even more good news. “We’ve got company, folks!” He pointed to the smoking tunnel.
From the heart of the enveloping blackness, pale shapes leaped forth like demons from hell. The creatures piled and writhed from the opening, screeching, bellowing. Claws scrabbled on rock.
“The explosions must have panicked them,” Maggie said. “Overcoming their fear of the tunnel.”
From the heights, black eyes swung in their direction. The keening wail changed in pitch.
“Run!” Henry bellowed, terrified at the sight. “Now!”
The group fled across the rough terrain. Chunks of basalt now rattled upon the quaking ground, sounding like the chatter of teeth. It made running difficult. Henry fell, scraping his palms on the jagged stone. Then Sam was there, pulling him to his feet.
