She hated him now more intensely than before, since he seemed, by some enormity of purpose, to have been in some manner responsible for the fate that had brought her here in his company, absolutely at his mercy. That his promptness of action had saved her life she willingly and justly conceded—but to fetch her here, all by herself, to an island unpeopled and awful, far from the track of ocean-going steamers—with his threat to compel her love still ringing in her ears—this seemed to outweigh any possible service he had done or could ever accomplish.
What would he do, she wondered, on the morrow? When would he speak of his passion again? What means, in this situation, might he presently adopt to coerce the love she knew she should never bestow?
There could be no answer to her questions—least of all from the man himself. He, too, had fallen into silence, and a study of the vast and merciless problems, not only of existence till their escape could be effected, but likewise as to how that escape could be attempted, in safety, and where they must steer their ocean course to come to a land which should not prove inhospitable.
He seemed, for the time, to have quite forgotten the presence of the girl at the cave. This she finally observed. She wondered, then, what sinister outcome his brooding might presage.
Keyed to a pitch of nervous sensibility she had never experienced before, she retired at length within her shelter like a child thrust alone in the dark. Much as she felt she disliked the man, she found herself most reluctant to move very far from his presence, or refuse his protecting care. She was certain her dread of all it meant to be hopelessly cast upon this island, with one doubtful human being only for comfort and companionship, would haunt her to sleeplessness throughout the night. Yet she fell into slumber almost at once, and only dreamed she was still awake and worried.
It was still quite early in the evening. Elaine was finally approaching a thoroughly restful oblivion, when a low, moaning wail, and then shrill screams, abruptly ushered once more into play that hideous chorus of the morning, produced by some phenomenon of the tides.
"Sidney! Sidney!" came an answering cry; and Grenville arose, to see Elaine running wildly towards him from her cave.
