No further engagement followed at the opera, and Consuelo's thoughts turned more and more to the Rudolstadts. If only she could hear from Christian or his son, she would know whether she was free to devote herself absolutely to her art. For she had made her promise to Count Christian that she would send him word should she feel sure of being in love with Albert; and now that word had been sent, and no reply had come. Porpora, with a promise of an engagement at the royal theatre in Berlin, and anxious to take Consuelo with him, had confessed, in answer to her objection to leaving Vienna before hearing from Christian, that letters had come from the Rudolstadts, which he had destroyed. "The old count was not at all anxious to have a daughter-in-law picked up behind the scenes," said Porpora, "and so the good Albert sets you at liberty."

At least, he says it will give him a hold on eternal life. I do not know what he means, but he has the gift of prophecy and the perception of hidden things. The doctors have given up all hope for his life." "Is the carriage ready, sir?" Consuelo said, when the latter was finished. "If so I am ready also, and we can set out instantly." "I shall follow you," said Porpora. "Only we must be in Berlin in a week's time." The carriage and horses were already in the courtyard, and in a few minutes the baron and Consuelo were on their journey to the castle of the Rudolstadts. At the doorway of the castle they were met by the aged canoness, who, seizing Consuelo by the arm, said:
