"I thought—it seemed very probable—that the scrap of writing you found would inform you who these were. If it was important enough for the dying man to try to swallow it, it certainly should give some clew to his assailant."

"Unfortunately, it does not do so. It was a veritable scrawl, madam, running something like this: 'I return your daughter to you. She is here. Neither she nor you will ever see me again. Remember Evelyn!' And signed, 'Amos's son.'"

"Amos's son! That is Mr. Adams himself."

"So we have every reason to believe."

"Strange! Unaccountable! And the paper inscribed with these words was found clinched between his teeth! Was the handwriting recognized?"

"Yes, as his own, if we can judge from the specimens we have seen of his signature on the fly-leaves of his books."

"Well, mysteries deepen. And the retaining of this paper was so important to him that even in his death throe he thrust it in this strangest of all hiding-places, as being the only one that could be considered safe from search. And the girl! Her first words on coming to herself were: 'You have left that line of writing behind.' Mr. Gryce, those words, few and inexplicable as they are, contain the key to the whole situation. Will you repeat them again, if you please, sentence by sentence?"

"With pleasure, madam; I have said them often enough to myself. First, then: 'I return your daughter to you!'"

"So! Mr. Adams had some one's daughter in charge whom he returns. Whose daughter? Not that young man's daughter, certainly, for that would necessitate her being a small child. Besides, if these words had been meant for his assailant, why make so remarkable an effort to hide them from him?"

"Very true! I have said the same thing to myself."
