He gazed over the edge into the blue-black emptiness. The drop was phantasmal; perhaps as much as a mile. He wondered if he would be allowed to descend it and inspect the valley civilization that had been talked of. The notion of this strange culture-pocket, hidden amongst unknown ranges, and ruled over by some vague kind of theocracy, interested him as a student of history, apart from the curious though perhaps related secrets of the lamasery.
Suddenly, on a flutter of air, came sounds from far below. Listening intently, he could hear gongs and trumpets and also (though perhaps only in imagination) the massed wail of voices. The sounds faded on a veer of the wind, then returned to fade again. But the hint of life and liveliness in those veiled depths served only to emphasize the austere serenity of Shangri-La. Its forsaken courts and pale pavilions shimmered in repose from which all the fret of existence had ebbed away, leaving a hush as if moments hardly dared to pass. Then, from a window high above the terrace, he caught the rose-gold of lantern light; was it there that the lamas devoted themselves to contemplation and the pursuit of wisdom, and were those devotions now in progress? The problem seemed one that he could solve merely by entering at the nearest door and exploring through gallery and corridor until the truth were his; but he knew that such freedom was illusory, and that in fact his movements were watched. Two Tibetans had padded across the terrace and were idling near the parapet. Good-humored fellows they looked, shrugging their colored cloaks negligently over naked shoulders. The whisper of gongs and trumpets uprose again, and Conway heard one of the men question his companion. The answer came: “They have buried Talu.” Conway, whose knowledge of Tibetan was very slight, hoped they would continue talking; he could not gather much from a single remark. After a pause the questioner, who was inaudible, resumed the conversation, and obtained answers which Conway overheard and loosely understood as follows:
“He died outside.”
“He obeyed the high ones of Shangri-La.”
“He came through the air over the great mountains with a bird to hold him.”
“Strangers he brought, also.”
“Talu was not afraid of the outside wind, nor of the outside cold.”
“Though he went outside long ago, the valley of Blue Moon remembers him still.”
Nothing more was said that Conway could interpret, and after waiting for some time he went back to his own quarters. He had heard enough to turn another key in the locked mystery, and it fitted so well that he wondered he had failed to supply it by his own deductions. It had, of course, crossed his mind, but a certain initial and fantastic unreasonableness about it had been too much for him. Now he perceived that the unreasonableness, however fantastic, was to be swallowed. That flight from Baskul had not been the meaningless exploit of a madman. It had been something planned, prepared, and carried out at the instigation of Shangri-La. The dead pilot was known by name to those who lived there; he had been one of them, in some sense; his death was mourned. Everything pointed to a high directing intelligence bent upon its own purposes; there had been, as it were, a single arch of intentions spanning the inexplicable hours and miles. But what was that intention? For what possible reason could four chance passengers in the British government aeroplane be whisked away to these trans-Himalayan solitudes?
Conway was somewhat aghast at the problem, but by no means wholly displeased with it. It challenged him in the only way in which he was readily amenable to challenge – by touching a certain clarity of brain that only demanded a sufficient task. One thing he decided instantly; the cold thrill of discovery must not yet be communicated, neither to his companions, who could not help him, nor to his hosts, who doubtless would not.
