These reasons, strong enough in themselves, did not soothe Rodolph's anxieties. At this juncture, Seyton was charged by the Grand Duke with an errand to visit several breeding studs in Austria. This mission, which he could not refuse, would only detain him a fortnight: he set out with much regret, and in a very important moment for his sister. She was chagrined, yet satisfied, at the departure of her brother; for she would lose his advice, but then he would be safe from the Grand Duke's anger if all were discovered. Sarah promised to keep Seyton fully informed, day by day, of the progress of events, so important to both of them; and, that they might correspond more surely and secretly, they agreed upon a cipher, of which Polidori also held the key. This precaution alone proves that Sarah had other matters to tell her brother of besides her love for Rodolph. In truth, this selfish, cold, ambitious woman had not felt the ice of her heart melt even by the beams of the passionate love which had been breathed to her. Her maternity was only with her a means of acting more effectually on Rodolph, and had no softening effect on her iron soul. The youth, headlong love, and inexperience of the prince, who was hardly more than a child, and so perfidiously ensnared into an inextricable position, hardly excited an interest in the mind of this selfish creature; and, in her confidential communications with him, she complained, with disdain and bitterness, of the weakness of this young man, who trembled before the most paternal of German princes, who lived, however, very long! In a word, this correspondence between the brother and sister clearly developed their unbounded selfishness, their ambitious calculations, their impatience, which almost amounted to homicide, and laid bare the springs of that dark conspiracy crowned by the marriage of Rodolph. One of Sarah's letters to her brother was abstracted by Polidori, the channel of their mutual communications; for what purpose we shall see hereafter.
A few days after Seyton's departure, Sarah was at the evening court of the Dowager Grand Duchess. Many of the ladies present looked at her with an astonished air, and whispered to their neighbours. The Grand Duchess Judith, in spite of her ninety years, had a quick ear and a sharp eye, and this little whispering did not escape her. She made a sign to one of the ladies in waiting to come to her, and from her she learned that everybody was remarking that the figure of Miss Sarah Seyton of Halsbury was less slender, less delicate in its proportions than usual. The old princess adored her young protégée and would have answered to God himself for Sarah's virtue. Indignant at the malevolence of these remarks, she shrugged her shoulders, and said aloud, from the end of the saloon in which she was sitting:
