By great good fortune Martina had quitted Susannah's house as soon as the two slaves had fallen ill and she had heard that the physician pronounced them to be sickening of the plague. She had returned to her rooms in the inn kept by Sostratus, but her nephew Narses had remained with Katharina and her mother. He was indeed intending to follow her with Heliodora; but, by the time they were ready to set out, Susannah, too, had fallen a victim to the pestilence and the authorities had forbidden all egress from her house. Heliodora might have succeeded in leaving in time, alone; but she would not abandon her unfortunate brother-in-law; for he never felt easy but in her presence, would allow no one else to wait on him, and would take neither food nor drink unless they were offered him by her. Besides this, the cavalry officer, once so stalwart, had in his weakness become pathetically like her lost husband, and she knew that Narses had been the first to love her, and that it was only for his brother's sake that he had concealed his passion. Her motherly instincts found an outlet in the care of the half-crushed, but not hopelessly lost man; and the desire to drag him back to life kept her busy day and night, and made her regard everything else as trivial and of secondary importance. Her life had once more found a purpose; her efforts were for an attainable end, and she devoted herself to him body and soul. Her uncle had told her that Orion was bound to Paula by a supreme passion.--This had been a painful blow, but the Syrian girl had impressed her; she looked up to her, and it soothed her wounded self-esteem to reflect that she had lost her lover to no inferior woman. Though her longing for him still surged up in many a silent hour, she felt it an injustice, a stint of love to her invalid charge. So far as Katharina was concerned, next to her mother, Heliodora was the object of her deepest anxiety. The least word of complaint from either terrified her; and if Susannah sank on the divan exhausted by the heat, or Heliodora had a headache after watching through the night by the sick man, the girl would turn pale, her heart would beat painfully, she would paint them in fancy stricken by the plague, with burning brows and the horrible, fatal spots on their foreheads and cheeks; and whenever these alarms pressed on the young criminal she felt the ominous weight on the top of her head where the dead bishop's hand had rested. The senator's wife had so completely changed in her demeanor to the water-wagtail, since Paula's imprisonment, that to Katharina she was as a living reproach, so she had no regret at seeing the worthy pair depart. But scarcely had they left when misfortune took their place as an unbidden guest.
