“I thank you for your congratulations and your good wishes, Miss Carleton, but I sometimes question whether my discovery, on that particular day, of the will — the last link in the chain of evidence against Hugh Mainwaring — was a matter for congratulation.”

“How is that?” she inquired, quickly.

“Do you not see that when all these facts become known, they may be used by my enemies to direct suspicion against me as the possible murderer of Hugh Mainwaring?”

“Who would think of such a thing?” she exclaimed, indignantly.

“Ralph Mainwaring will,” was his prompt reply.

“He might try to incite the suspicions of others against you, but he would know in his own heart that his insinuations were unfounded.”

“I have no fear of him,” said Harold, with a smile; “I only mentioned it to show that I do not anticipate upon my return to America that my pathway will be strewn with roses.”

He paused a moment, then added, “I had this in mind, Miss Carleton, when I asked you once whether your confidence in me were strong enough to stand a heavy strain, if necessary.”

She blushed slightly at the reminder, and a look of quick comprehension flashed across her face, as, for an instant, she dropped her eyes before his earnest gaze.  When she again looked up the luminous eyes met his own unwaveringly, as she replied, in firm, low tones,-

“I will believe in you and trust you to the fullest extent, whatever happens.”

“I thank you more than I can express,” he answered, gravely; “for, believe me, Miss Carleton, I value your confidence and friendship far above any and every other.”

“I did not suppose you needed any assurance of my friendship; though, after your sudden departure from Fair Oaks, I felt somewhat doubtful whether you cared for it.”

He did not reply at once, and when he did, it was evident he was repressing some strong emotion.  “I feel that there is an explanation due you for my manner of leaving Fair Oaks.  I am aware that it had the appearance of rudeness, but I can only say that it was from necessity and not from choice.  There is something more which I hope some day to tell you, Miss Carleton, but, until I can speak as I wish to speak, it is best to remain silent; meanwhile, I will trust to your friendship to pardon whatever in my conduct may seem abrupt or inexplicable.”

The conversation was terminated at this point by the appearance of Lieutenant Cohen, whom Harold Mainwaring introduced as an old classmate, and presently all three adjourned to the dining-saloon.

To Harold Mainwaring and Miss Carleton the remainder of the voyage passed swiftly and pleasantly, and the friendship begun at Fair Oaks deepened with each succeeding day.  Though no word of love passed between them, and though Miss Carleton sometimes detected on the part of her companion a studied avoidance of personal subjects, yet, while wondering slightly at his self-imposed silence, she often read in his dark eyes a language more eloquent than words, and was content to wait.
