Knox hurtled down the cliff-face past Abdullah towards the wadi floor. But he was still gripping the rope tightly in both hands, and its other end was looped through Abdullah's belt, so that the momentum of Knox's fall transferred instantly to him. Knox slammed against the cliff, grabbed rock, let go of the rope. But Abdullah wasn't so fortunate. His knees buckled, his right foot slipped from the wet narrow ledge, his hand was ripped free from its hold inside the tomb. He tumbled shrieking past Knox, clawing the sky, and slapped the rocks beneath with a sickening thump. Then only silence.
A cascade of stones clattered by. Knox looked up to see Khaled on the cliff edge, pointing down his torch and aiming his pistol, squeezing off four rounds that pinged and whined off the rocks. Knox scrambled up to the ledge where Abdullah had been, gaining the protection of a slight overhang. There was a gaping hole in the rock, he saw, big enough for him to squeeze through. He tumbled through to the other side. A torch was lying on the ground. He picked it up and shone it around a chamber, ankle deep in water. He splashed over to a passage leading off and then down. 'Gaille!' he shouted. 'Gaille!'
A cry ahead. A woman's cry: high-pitched, short, terrified. Not Gaille, though. Lily, the other hostage. And panic rather than relief in her voice. He raised his pace, running headlong, almost didn't see the shaft in time, stopped teetering on its waterfall brim, regained his balance, shone down his torch, picked out Lily fifteen or twenty feet below, clinging to the wall, surrounded by a flotsam of crushed water bottles and wooden planks, keeping Gaille's head above the water with the crook of her elbow, but crying out in pain and exertion.
'Hold on!' cried Knox.
'I can't. I can't.'
He looked around for some way to get down to her and then back up again. Any way. He saw an iron peg hammered into the floor, but there was nothing to tie to it. And Abdullah had taken the rope down with him on his plunge.
'Help!' cried Lily. 'Help!' A spout of rainwater fell on her open mouth, catching in her throat, making her choke and splutter, flailing around in the water, letting go of Gaille, who promptly slipped beneath the surface.
'Gaille!' yelled Knox. 'Gaille!'
Lily splashed over to the wall, clawed onto it with both hands. 'I'm sorry,' she wept. 'I'm sorry.'
Knox had no time to think. No time at all. He gripped his torch tight, yelled out in fear, and leapt feet-first into the shaft.
