Half an hour later, when Jack was lying at full length on the rock, lazily staring into the gloomy heights above him, a sudden, low, sharp cry broke into the stillness. The cry had been uttered by the watcher at the mouth of the cave, and now he said a few quick words. The elder Panthay leapt to his feet and shot down the cave with the glide of a panther. Jack sprang from his rock and followed.
The English lad had known at once that the cry meant danger, so deep an anxiety had lain in the low troubled note. As he crept up to the boulder behind which the two Panthays crouched, he saw that the peril which threatened him a short time ago still hung over his head. Looking through the hole, they commanded a full view of the upper edge of the opposite side of the ravine. Gathered aloft there, in full sight, was a bunch of figures, and, in the front of the group, the scarlet and yellow turbans still blazed.
Jack knew at once that danger was closer than ever. By some means Saya Chone and the Strangler knew that he and his guides had turned aside from the ordinary track, and had followed on their new trail.
Now their pursuers began to climb down the steep side of the ravine, led by a Panthay tracker. In a moment Jack saw that the man was following the path they had followed. His quick eye was marking the displaced stones and torn creepers, and he was leading Saya Chone and the Strangler straight upon their prey.
Jack looked swiftly round the cave in which they stood. Did it offer any securer hiding-place than the part in which they were? To leave it was impossible! They could only step out in full sight of the advancing band of enemies. He looked at the Panthays and saw that they could render him no help. They were trembling like leaves with terror. He caught a name on the elder Panthay's lips, and knew it.
"Saya Chone," the man was murmuring. "Saya Chone."
"Oh," thought Jack, "this fellow recognises the half-caste and fears the vengeance of a powerful enemy. Then we can't be far now from the country where the Ruby King rules the roost. But the point for the moment is, how to dodge Mr. Saya Chone."
He beckoned to the Panthays to follow him, and all three retreated to the depths of the cave. The elder Panthay ran ahead, waving his hand to Jack to follow.
"Hullo!" thought Jack, "looks as if this chap knew of a spot to hide in," and he hurried forward. At the lower end of the cave the roof dipped sharply down, and the sides closed in, forming a tunnel about six feet high and five feet wide. This tunnel was three or four yards long, and then it opened out again into a second cave of fair size. The second cave was dimly lighted from a rift in the rock, forty feet above their heads. In two minutes Jack had made the circuit of it, and knew that, except for the fact that it was an inner cave, it offered them no refuge. The walls were smooth and unclimbable, and there was no break in them except at the point where the tunnel ran in.
Jack returned from his swift search and peered down the tunnel. From the cool darkness he looked out and saw a ring of brilliant light, the mouth of the outer cave. Suddenly a head shot into the patch of blinding sunlight without. The head was covered with a yellow turban, and Jack saw the Strangler slowly draw himself up and stand in the mouth of the cave. The big Malay did not rush forward. Instead, he stood gazing curiously about, and then Jack understood. He and his companions had left no track on the smooth hard rocks which paved the bottom of the ravine, and their enemies were not certain in which cave they lay; each cave was being searched in turn.
