After she had told the knight the purpose of the letter, she left him; the vesper service summoned her, and afterward Barbara detained her as she sang to the Emperor, alone and accompanied by Appenzelder's boy choir, several songs, and in a manner so thoroughly artistic that the Queen lingered not only in obedience to her brother's wish, but from pleasure in the magnificent music, until the end of the concert. Just as Wolf, seated in the writing room, which was always at his disposal, finished the letter, the major-domo, Don Luis Quijada, sought him. He had already intimated several times that he had something in view for him which promised to give Wolf's life, in his opinion, a new and favourable turn. Now he made his proposal. The duties imposed upon him by the service compelled him to live apart from his beloved, young, and beautiful wife, Dona Magdalena de Ulloa, who had remained at his castle Villagarcia in Spain. She possessed but one true comforter in her solitude--music. But the person who had hitherto instructed her--the family chaplain--was dead. So far as his ability and his taste were concerned, it would have been easy to replace him, but Quijada sought in his successor qualities which rarely adorned a single individual, but which he expected to find united in the knight. In the first place, the person he desired must be, like the chaplain, of noble birth; for to see his wife closely associated with a man of inferior station was objectionable to the Spanish grandee, who was perhaps the most popular of all the officers in the army, not only on account of his valour in the field, but also for the kindly good will and absolute justice which he bestowed upon even the humblest soldier. That the chaplain's successor must be a good artist, thoroughly familiar with Netherland and Italian music, was a matter of course. But Don Luis also demanded from Dona Magdalena's new teacher and household companion graceful manners, a modest disposition, and, above all things, a character on which he could absolutely rely. Not that he would have cherished any fears of the fidelity of the wife whom he honoured as the purest and noblest of her sex, and of whom he spoke to the knight with reverence and love; he desired only to guard her from any occurrence that might offend her. Wolf listened in surprise. He had firmly resolved that on no account would he stay in Ratisbon. What could he find save fresh anxiety and never-ending anguish of the heart if he remained near Barbara, who disdained his love?
