Marston, on his part, however much his conduct might tend to confirm suspicion, certainly did nothing to dissipate the painful and undefined apprehension respecting himself, which Mademoiselle de Barras, with such malign and mysterious industry, labored to raise.  His spirits and temper were liable to strange fluctuations.  In the midst of that excited gaiety, to which, until lately, he had been so long a stranger, would sometimes intervene paroxysms of the blackest despair, all the ghastlier for the contrast, and with a suddenness so abrupt and overwhelming, that one might have fancied him crossed by the shadow of some terrific apparition.  Sometimes for a whole day, or even more, he would withdraw himself from the society of his family, and, in morose and moody solitude, take his meals alone in his library, and steal out unattended to wander among the thickets and glades of his park.  Sometimes, again, he would sit for hours in the room which had been Sir Wynston’s, and, with a kind of horrible resolution, often loiter there till after nightfall.  In such hours, the servants would listen with curious awe, as they heard his step, pacing to and fro, in that deserted and inauspicious chamber, while his voice, in broken sentences, was also imperfectly audible, as if maintaining a muttered dialogue.  These eccentric practices gradually invested him, in the eyes of his domestics, with a certain preternatural mystery, which enhanced the fear with which they habitually regarded him, and was subsequently confirmed by his giving orders to have the furniture taken out of the ominous suite of rooms, and the doors nailed up and secured.  He gave no reason for this odd and abrupt measure, and gossip of course reported that the direction had originated in his having encountered the specter of the murdered baronet, in one of these strange and unseasonable visits to the scene of the fearful catastrophe.

In addition to all this, Marston’s conduct towards his wife became strangely capricious.  He avoided her society more than ever; and when he did happen to exchange a few words with her, they were sometimes harsh and violent, and at others remorsefully gentle and sad, and this without any changes of conduct upon her part to warrant the wayward uncertainty of his treatment.  Under all these circumstances, Mrs. Marston’s unhappiness and uneasiness greatly increased.  Mademoiselle de Barras, too, upon several late occasions, had begun to assume a tone of authority and dictation, which justly offended the mistress of the establishment.  Meanwhile Charles Marston had returned to Cambridge; and Rhoda, no longer enjoying happy walks with her brother, pursued her light and easy studies with Mademoiselle de Barras, and devoted her leisure hours to the loved society of her mother.

One day Mrs. Marston, sitting in her room with Rhoda, had happened to call her own maid, to take down and carefully dust some richly bound volumes which filled a bookcase in the little chamber.
