But where on earth was she going to lead him? On, on, she pressed, walking swiftly, and although the ground itself was, in places, none of the smoothest, yet, while not seeming to notice the way, she sped over it almost quicker than he did, looking carefully where he was going. It was a weird sort of undertaking. He could see in the moonlight her splendid hair streaming like a mantle about her shoulders, and noted the grace and ease with which she walked. On--ever. They were nearing the edge of the plain--and lo!--there in front of them rose the mountain which was cleft by the great _tangi_--the haunted _tangi_, equally feared seemingly by the enlightened and highly-educated Europeans who were his fellow-travellers as by the superstitious natives of the land. Straight for this the unconscious pedestrian was heading. What strange influence was drawing her thither, thought he who followed: and for the first time something of the superstitious shrinking which caused them to shun the place began to creep over him. He glanced over his shoulder with some faint hope that others might have discovered the girl's absence and be following, but no. All was dead and silent. Nothing moved in the silvery moonlight. And now in front rose the great rock portal--and on, ever on, kept the white and gliding figure before him. He saw it stand forth whiter than ever against the gloom of the entrance, then disappear, swallowed within the cavernous blackness of the great chasm. Would the sudden change both of light and atmosphere awaken her? Would she come rushing forth wild with terror, instinctively making for the light? For a moment he waited in case this should be so--then plunged within the darkness of the place. Raynier felt that here her wandering would end. Some strange psychological wave, acting with their experience of the day before, stimulated by the subject of their conversation that evening, had moved her to rise in her sleep and come hither. But to what end? There was something uncanny about her, Haslam had remarked, but Raynier was conscious of a very lively sense of thankfulness that he had been awake, and thus ready to follow and watch over her on this eerie and far from safe adventure upon which she had all unconsciously embarked. The light from without hardly penetrating here, Raynier found himself slipping and stumbling in the gloom, yet, with it all, his quick ears could hear the footsteps in front moving easily and firmly without trip or stumble. It was marvellous--nor did the noise he made on the rattling stones seem in any way to disturb her whom he followed.
