On the 19th of July the tide was at low ebb at half-past two in the afternoon; and at three o’clock Alixe entered the cave, and climbed, dry-shod, up to her ledge of rock. Here, as she knew, she was safe for two hours, if she chose to stay so long. The interior of this cave was by no means an uninteresting place, though Alixe had never yet explored it beyond the space of twenty feet, where it was bright with the daylight that poured in through its jagged entrance. After that it wound a darker way into the cliff, and the far recesses were lost in utter blackness. A spoken word directed toward the inner passage-way would reverberate along that mysterious interior till one could not but be a little awed at the vast extent of the lost passage. The visible floor of the cavern was a thing of interest and beauty, for at low tide it was like a little park, where pools of clear sea-water alternated with groves of filmy plants, small ridges of pebbles and rocks, and patches of delicately ribbed sand, where every species of shell-fish dwelt. At times Alixe spent hours in studying sea-life in these places; and certainly, on hot summer afternoons, no pleasanter occupation could have been found. Probably others than Alixe would have taken to it, were it not for the fact that the cave was the scene of one of the weirdest legends of the coast, and was held in avoidance as much by Castle folk as by the peasantry. Alixe, however, had long been held to possess some uncanny power over the people of the supernatural world, for she would venture fearlessly into the most unholy spots, emerging unharmed and undisturbed; nor could any one ever learn from her whether or not she had actually held intercourse with the creatures whom they devoutly believed in, and so devoutly dreaded. To-day, certainly, there was no suggestion of the uncanny about her as she lay upon her ledge of rock, looking off upon the sparkling waters that danced up to the very edge of her retreat. With one hand she shaded her eyes from the golden glare, and her head was pillowed on her other arm. Her usually smooth brow was puckered into a frown for which the sun was not responsible; nor yet was Alixe’s mind upon any subject that might be supposed to anger or distress her. For the moment she had dropped her inward debate, and was lazily watching the sea. The warmth of the afternoon had made her drowsy, and now the shadowy coolness of the cave soothed her till her vivid mental images had become a little blurred, and the sparkle of the water and its crispy rustle, as it advanced and retreated over the sand outside, was luring her mind into the faery wastes of dreamland. She wondered a little whether she were awake or asleep; but, in point of fact, her eyes were not actually shut, when a slender figure came round a corner of the entrance, and slipped lightly into the cave.
