But, what a long time Stella was coming back! If she had let him out at that door, she surely should have found her way up the cliff before now. Katherine turned in that direction, and stood still at the top of the path and listened, but could hear nothing. Perhaps she had been mistaken about the click of the door. It was very dark in that deep shadow--too dark to penetrate into the gloom by herself without a lantern, especially as, after all, she was not quite sure that Stella had gone that way. She must at least wait a little longer before making any search which might betray her sister. She turned back again, accordingly, along the round of the broad cliff with its feathering edge of tamarisks. Oh, what a wonderful world of light and stillness! The white cliff to the east shone and flamed in the moonlight; it was like a tall ghost between the blue sea and the blue sky, both of them so indescribably blue--the little ripple breaking the monotony of one, the hosts of stars half veiled in the superior radiance of the moon diversifying the other. She had never been out on such a beautiful night. It was a thing to remember. She felt that she should never forget (though she certainly was not fond of him at all) the night of Charlie Somers’s departure--the night of the ball, which had been the finest Sliplin had ever known. As Katherine moved along she heard in the distance, beginning to make a little roll of sound, the carriages of the people going away. She must have been quite a long time there when she perceived this; the red fire in the hall was only a speck now. A little anxious, she went back again to the head of the path. She even ventured a few steps down into the profound blackness. “Stella!” she cried in a low voice, “Stella!” Then she added, still in a kind of whisper, “Come back, oh, come back; it is getting so late.” But she got no reply. There were various little rustlings, and one sound as of a branch that crushed under a step, but no step was audible. Could they be too engrossed to hear her, or was Stella angry or miserable, declining to answer? Katherine, in great distress, threaded her way back among the trees that seemed to get in her way and take pleasure in striking against her, as if they thought her false to her sister. She was not false to Stella, she declared to herself indignantly; but this was too long--she should not have stayed so long. Katherine began to feel cold, with a chill that was not of the night. And then there sounded into the clear shining air the stroke of the hour. She had never heard it so loud before. She felt that it must wake all the house, and bring every one out to see if the girls had not come back. It would wake papa, who was not a very good sleeper, and betray everything. Three! “Stella, Stella! oh, for goodness’ sake, don’t stay any longer!” cried Katherine, making a sort of funnel of her two hands, and sending her voice down into the dark.
