Putting his aches and pains aside, he took the lead again. The passageway went down at a shallow angle for a few hundred feet before leveling out. The trek had taken its toll on Schroeder's ankle, and he had to lean against the wall a number of times to keep from falling. They were in danger of losing the race with their pursuers.

Karla was the first to see the cleft in the wall. Schroeder had been so intent on putting distance between them and their pursuers that he had walked by the wrinkle in the limestone where the wall folded in on itself, creating a narrow opening little more than a foot wide and five feet tall.

Schroeder's first instinct was to keep going. The hole could be a death trap. He stuck his head through and saw that the tunnel actually widened after a few feet. He told Karla to wait and he walked for fifty paces or so along the main cave. He placed his flashlight on the floor as if it had been dropped in haste.

The voices got louder. He went back to where Karla was waiting, squeezed his tall body through the cleft, then helped Karla through. They kept moving until they found a place where the cave curved slightly. He slipped the rifle off his shoulder and flattened his back against the wall. The first man through the hole would be dead.

They could see the ghostly glow of lights from the main tunnel. Grisha's harsh voice was clearly identifiable as he urged his men on with threats and jokes. The ivory hunters passed the crevice, and there was an excited yell. They had seen the flashlight. The voices receded.

Schroeder's intention was to slip back into the main tunnel and backtrack, but Grisha was no fool. He must have assumed that the flashlight's placement was too convenient to have been accidental. He and his men turned around and came back to the cleft in the wall.

Schroeder whispered in Karla's ear to get moving. As they hurried through the winding passageway, Schroeder decided their only course of action was to remain on the run. The flashlight beam was growing dimmer, indicating that the batteries were weakening. He would have to pick an ambush spot before they became lost or found themselves deep in the mountain with no light to show the way.

They walked for another ten minutes. The air was musty but it was still breathable, indicating that there was a flow coming in from the outside. The cave narrowed, and Schroeder saw a narrow fissure ahead. He stepped through the breach and his foot came down on thin air. He crashed down onto a slope and rolled several feet.
