"I sit here often," she replied, "before going to bed in my room behind. The rooms are too warm. I disturb no one."

For a moment he felt disposed to say that it would disturb him if she should again take it into her head to turn his blinds, but, on second considerations, he held his peace. To know a thing and not to divulge one's knowledge is, he reflected, sometimes to possess a secret--a clue--a warning worth having; to possess, indeed, something that may be of use to us in the future if not now, while, for the rest--well! the returning of the spray to her had, doubtless, informed the girl sufficiently that he was acquainted with the fact of how she had been outside his window, and that it was she who had opened his blind wide enough to allow her to peer in on him.

"Good-night," he said, turning away. "Good-night," and without waiting to hear whether she returned the greeting or not, he went back to the bedroom. Yet, before he entered it, he bent over the balcony and called down another "good-night" to Sebastian, who, he noticed, had now been deserted by Madame Carmaux.

For some considerable time after this he walked about his room; long enough, indeed, to give Sebastian the idea that he was preparing for bed, then, although he had removed none of his clothing except his boots, he put out the lamp.

"If the young lady is desirous of observing me again," he reflected, "she can do so. Yet if she does, it will not be without my knowing it. And if she should pay me another visit--why, we shall see."

But, all the same, and because he thought it not at all unlikely that some other visitor than the girl might make her way, not only to the blind itself but even to the room, he laid his right arm along the table so that his fingers were touching the revolver that he had now placed on that table.

"I haven't taken countless middle watches for nothing in my time," he said to himself; "another won't hurt me. If I do drop asleep, I imagine I shall wake up pretty easily."

He was on the alert now, and not only on the alert as to any one who might be disposed to pay him a nocturnal visit, but, also, mentally wary as to what might be the truth concerning Sebastian Ritherdon and himself. For, strange to say, there was a singular revulsion of feeling going on in his mind at this time; strange because, at present, scarcely anything of considerable importance, scarcely anything sufficiently tangible, had occurred to produce this new conviction that Sebastian's story was untrue, and that the other story told by his uncle before his death was the right one.

All the same, the conviction was growing in his mind; growing steadily, although perhaps without any just reason or cause for its growth. Meanwhile, his ears now told him that, although Madame Carmaux was absent when he glanced over the balcony to wish Sebastian that last greeting, she undoubtedly had not gone to bed. From below, in the intense stillness of the tropic night--a stillness broken only occasionally by the cry of some bird from the plantation beyond the cultivated gardens, he heard the soft luscious tones of the woman herself--and those who are familiar with the tones of southern women will recall how luscious the murmur can be; he heard, too, the deeper notes of the man. Yet what they said to each other in subdued whispers was unintelligible to him; beyond a word here and there nothing reached his ears.

With the feeling of conviction growing stronger and stronger in his mind that there was some deception about the whole affair--that, plausible as Sebastian's possession of all which the dead man had left behind appeared; plausible, too, as was his undoubted position here and had been from his very earliest days, Julian would have given much now to overhear their conversation--a conversation which, he felt certain, in spite of it taking place thirty feet below where he was supposed to be by now asleep, related to his appearance on the scene.
