As the words passed her lips, she heard a movement, and softly and silently as a spirit, her brother Andrew, fully dressed, passed through the doorway. His arm lightly touched Christina's clothing, but he was unconscious of her presence. He looked more than mortal, and was evidently seeing through his eyes, and not with them. She was afraid to speak to him. She did not dream of touching him, or of arresting his steps. Without a sign or word, he went rapidly down the cliff, walking with that indifference to physical obstacles which a spirit that had cast off its incarnation might manifest.
"He is walking in his sleep, and he may get into danger or find death itself," thought Christina, and her fear gave strength and fleetness to her footsteps as she quickly followed her brother. He made no noise of any kind; he did not even disturb a pebble in his path; but went forward, with a motion light and rapid, and the very reverse of the slow, heavy-footed gait of a fisherman. But she kept him in sight as he glided over the ribbed and water-lined sands, and rounded the rocky points which jutted into the sea water. After a walk of nearly two miles, he made direct for a series of bold rocks which were penetrated by numberless caverns, and into one of these he entered.
Hitherto he had not shown a moment's hesitation, nor did he now though the path was dangerously narrow and rocky, overhanging unfathomable abysses of dark water. But Christina was in mortal terror, both for herself and Andrew. She did not dare to call his name, lest, in the sudden awakening he might miss his precarious foothold, and fall to unavoidable death. She found it almost impossible to follow him nor indeed in her ordinary frame of mind could she have done so. But the experience, so strange and thrilling, had lifted her in a measure above the control of the physical and she was conscious of an exaltation of spirit which defied difficulties that would ordinarily have terrified her. Still she was so much delayed by the precautions evidently necessary for her life, that she lost sight of her brother, and her heart stood still with fright.
Prayers parted her white lips continually, as she slowly climbed the hollow crags that seemed to close together and forbid her further progress. But she would not turn back, for she could not believe that Andrew had perished. She would have heard the fall of his body or its splash in the water beneath and so she continued to climb and clamber though every step appeared to make further exploration more and more impossible.
