four faces, but only one of them was not half hidden beneath a black hood. Drake swore.
“Sully, stop!”
But Drake could see in his eyes that Sully did not know him. The Sully who had been his best friend for nearly twenty years did not live behind those eyes anymore. Sully did not know him.
For half a second, Drake wondered if he could shoot him just to wound, but he wasn’t that good a marksman and they’d never be able to carry him out of the labyrinth if he couldn’t walk on his own.
It was half a second too long.
“Sully, it’s me!” Drake yelled.
Then Sully barreled into him with enough force to knock the flashlight from his hand and the air from his chest. Drake staggered backward, only just managing to hold on to his gun as Sully put both hands around his throat and squeezed.
Struggling, trying to retreat, Drake felt his boot slip off the plateau’s rocky edge. Jada screamed his name, and then he and Sully were falling. They plunged into the cold, roaring river, Sully still with his hands wrapped around Drake’s throat. Drake’s mind was screaming for oxygen, his chest tight and burning after Sully had knocked the air out of him, and he wondered if Sully or the river would do him in.
Then they were spilling over the waterfall, falling, punished and dragged downward, and he realized it would be the fall that killed him.

Drake thrashed in the water, tearing loose from Sully’s grip. The river rushed around him, but for long drowning seconds he could not discern up from down, life from death. Then his left foot hit something hard and unyielding, and he knew that it must be below. Fighting to keep himself from flipping over again in the powerful current, he thrust his legs down, struck bottom, and propelled himself upward. His chest convulsed with the need for air, and when at last he broke the surface, he gave himself over to a helpless primal gasping, his mind devoid of reason, desiring only to breathe.
A hand snagged his shirt, and then Sully latched on to him, arms and legs wrapped around him from behind, trying to force him down. Drake shot an elbow into his gut, felt the sharp exhalation behind him, then reached around and put Sully in a headlock. Choking and dragging him at the same time, he pushed for the rocky riverbank. He’d dropped his flashlight up on the plateau, and though he didn’t remember letting go of his gun, he had lost it when they’d plunged over the waterfall. All he had to fight with were his hands and his wits, and he hoped they wouldn’t fail him.
Only the dimmest light existed down there in the lower cavern. It might as well have been pitch-dark save for the gleam of moonlight and reflected illumination from wavering flashlight beams above. That wet blackness gave form to rocks and walls and its absence indicated the presence of tunnel mouths, but otherwise Drake was in darkness.
He felt the river bottom underfoot and knew he must be near the bank. The roar of the waterfall on his right made it hard to hear much else, yet another churning noise came from his left, and he glanced that way to see the glistening blackness of a vertical rock face—the far end of the cavern. The river flowed into a tunnel at the base of the rock.
Panic raced through him. His throat raw from nearly drowning, his profanity-laced mutterings came out a meager rasp, but in his mind he was shouting. If they were dragged into that river tunnel, the darkness would be complete, and there was no way to know when or if they would enter another cavern where they might climb out. The underground river might go on for miles, joining the Qin Huai or Yangtze somewhere beyond the city of Nanjing. By then, they probably would be dead.
Drake tried to hoist Sully from the water, staggering toward shore, fighting the current. Sully had seemed disoriented, but now he thrashed against Drake’s choke hold, elbowed his ribs, and clawed at his hands. He twisted and bucked, and Drake lost his footing. Then he fell into the torrent again, washing toward the back of the cavern to vanish into the subterranean river’s hidden path forever.
“No!” Drake screamed, getting his footing, grabbing Sully around the torso as if tackling him.
He drove Sully toward the shore, dragging them both waist deep through the water even as
