Ommony lay on the bed in the tent and forced himself to accept the situation calmly. There was no use in racking his brains; the mystery now had become still more involved by the fact that Sirdar Sirohe Singh was a member of the Secret Service, who considered himself obligated to report unusual incidents to McGregor and yet did not hesitate to lend a hand in obscuring the very trail he had requested McGregor to investigate; who instantly returned the secret identification signal, and yet refused to give information; who had been ordered by McGregor to remain in Tilgaun and observe events, and yet did not mind showing himself within two days’ march of Delhi (nearly a thousand miles from Tilgaun) to a fellow member of the Secret Service, who he had no reason to suppose would not report him!
The mystery increased again when night fell. The same dumb, nondescript servant who had brought breakfast came with supper and hovered twenty yards away, signaling with a white cloth when Ommony had finished eating. Promptly in answer to the signal the sirdar stepped out from the trees with a lantern and called for Gupta Rao in a loud voice, retreating as Ommony advanced toward him until, on the far side of the belt of trees. Ommony was aware of shadowy forms of men—horses, at least a dozen of them in a long line, with gaps between—great shadowy carriages that filled the gaps as he drew nearer—and at last, smiling as placidly as if the new moon that shone like a sliver of pure gold over his shoulder were a halo he had just discarded, the Lama himself.
Samding was in attendance, moving about among the horses, patting them; Ommony noticed him ease a bearing rein. The Lama nodded to Ommony, stepped into the foremost carriage followed by Samding, and drove away at a gallop, the carriage swaying like a big gun going into action. Sirdar Sirohe Singh pushed Ommony into the next carriage (which had only four horses, whereas the Lama’s had six) allowed Diana just sufficient time to jump in behind him, and slammed the door, almost shutting it on the dog’s tail. A whip cracked instantly and the carriage started rocking and bumping in the Lama’s wake. A moment later a third and a fourth carriage followed.
Within was almost total darkness. There were two windows made of slats, forming part of the doors; Ommony tried them both, but the slides were nailed in position. He opened a door and swung himself out on the footboard to get a view of the following carriages, which he could just discern through the gloom and the cloud of dust, their drivers swaying on the high box-seats and shouting as they plied the whip. There was no way of guessing whether Dawa Tsering had been left behind or not. He climbed back into the carriage, holding the door open, but could not see much except dust, darkness and occasional shadowy tree-trunks.
The pace was furious. The flight was evidently prearranged, and managed perfectly. Horses were changed every ten miles or so, but whenever that happened men came to either side of Ommony’s carriage and held the doors shut, riding on the footboards afterward until the place where the change was made was out of sight. The route, except at intervals, did not lie along macadamed roads; once they lurched into a dry stream-bed and followed that for a mile or two, the wheels sinking in sand. But that, too, had been foreseen; men were waiting there, who ran alongside and seized the wheels whenever they sunk too deep, toiling as silently and smartly as a gun crew.
It was almost dawn when they rumbled over the paved streets of a fair-sized town, but there was nothing to show what town it was. At last squared stones rang underfoot, a great gate slammed, and a Tibetan opened the carriage door. Ommony found himself in a courtyard in front of what looked like a temple door, only there seemed to be no temple at the back of it—nothing but a wall and a dense thicket of trees on ground that sloped up-hill for more than a mile.
The Tibetan, taking him by the elbow, led him up steps through the entrance and down again into a cavern that was lighted with little imported kerosene lamps set in niches in the hewn rock walls. There was a maze of passages to right and left, and one wide tunnel that wound snake-wise until it opened into a vault, part natural and part very ancient masonry, that would have held five thousand people.
The Tibetan led him across that great crypt, down a passage at the far end, through a short tunnel into a shaft about fifty feet square at the base. Its sides sloped inward so as to be utterly unclimbable and seventy or eighty feet overhead was a patch of sky not more than twenty feet across.
In the midst, exactly under the square patch of daylight was a tank, brim-full of clean water. On every side of the enclosure there were square openings half-concealed by curtains made of matting. Ommony was led through one of those into a cave about twenty feet long, very plainly but quite comfortably furnished, and there the Tibetan left him without a word.
There was no restraint placed on him; he went and sat down in the opening, watching the dawn gradually fill the place with light until the clouds shone clearly reflected in the shallow tank.
