The cold, sneering tone scarcely tended to allay the confusion felt by the other at this reminder. This, then, was the apparition seen by Nidia, and he had been able to draw near enough to overhear their conversation with reference to his appearance. The thought was sufficiently uncomfortable. Who could the man be? That he was an eccentricity was self-evident. He went on—

“You were right in saying that your ‘friend’ would be terribly frightened. She has gone through such a night as she hopes never to spend again, and her fears are not over, but this time they are very material, and are for herself. There are shapes stealing upon her down the rocks—dark shapes. Natives? No. Human? No. What then? Beasts. She screams; tries to drive them off. They grow bolder and bolder—and—”

“Heavens alive, man, don’t drive me mad!” roared John Ames, whirling up from his couch, forgetful alike of aching bones and bruised and shaken frame. “What, is it you see—or know? Are you the devil himself?”

But the face of the seer remained perfectly impassible. Not so much as a finger of his moved. His eyes seemed to open wider, then to close; then to open again, as one awakening from a trance. Their expression was that of slight, unperturbed surprise.

“Look here, now,” said John Ames, quickly and decidedly. “You have taken care of me when I was in a bad fix, and most likely saved my life. I am deeply grateful, and hope we shall get to know each: other properly. But just now I must not lose a moment in going back to my friend, and if you won’t go with me, I’ll ask you to put me into my bearings.”

The stranger did not move in his attitude, or relax a muscle.

“You can’t go from here now,” he said; “nor, in fact, until I allow you.”

“Can’t? But I must!” shouted John Ames. “Heavens! I don’t see how you can know all you have been saying; but the bare suggestion that she may be in danger—all alone and helpless—oh, good God, but it’ll drive me mad!”

“How I can know? Well, perhaps I can’t—perhaps I can. Anyway, there’s one thing you can’t do, and that is leave this place without my aid. If you don’t believe me, just take a look round and try.”

He waved his hand with a throw-everything-open sort of gesture. In feverish strides, like those of a newly caged tiger, John Ames quickly explored the apartment, likewise another which opened out of it. His mind fired with Nidia’s helplessness and danger, he gave no thought to the curious nature of this subterranean dwelling; all he thought about was means of egress.
