In 1888 Tschaikovski went to Berlin. There Désirée was the idol of the court and public. They met now as friends. He and Edvard Grieg called at her house, and he wrote in his diary: "This evening is counted among the most agreeable recollections of my sojourn in Berlin. The personality and the art of this singer are as irresistibly bewitching as ever." _Requiescat in pace_! She had taught him the pangs of disprised love, but she had escaped misery, and she seems to have lived happily ever afterward with a husband who won eminence equal to hers as a singer. As for Tschaikovski, he had already revenged himself in kind--in worse kind--upon the sex, which had really attracted him only once. In the year 1875 Tschaikovski's nerves had gone to pieces from overwork and his mode of life. For months he was not allowed to write down a note. And now, I think some one must have prescribed marriage as a cure for his ills. There followed that strange affair which was a riddle as late as the time Miss Newmarch's biography appeared in 1900; a solution was then hoped from a sealed document left by Kashkin, and not to be opened till the year 1927. Tschaikovski himself had looked over his own diary, and had been so terrified at what he read that he destroyed a great portion of it before his death in 1893. In 1902, however, his brother Modeste began the publication of a very elaborate and complete biography, which partially clears the riddle. This is what we learn from that: In 1875 Tschaikovski was a wreck. In 1876 he suddenly wrote his brother: "I have resolved to marry--the resolve is beyond recall;" and again: "The result of my thought is the firm resolve to marry with whomsoever it may be." His photograph at this time has a worn, hunted look, and he has become addicted to cold baths, of which his new plan was the coldest of all. In May, 1877, his friend Kashkin suspected him of being engaged. In July, Kashkin was amazed to find him married. Just once Kashkin saw the couple together. Then Tschaikovski grew very distant to his friends and eccentric in his manner; a little later he fled to Moscow, and in a few days came word that he was dangerously ill. Later there were threats of suicide, but it was all a mystery. We know now that late in June, 1877, Tschaikovski announced definitely to his brother Anatol, that he was engaged to, and would soon marry, Antonina Ivanovna Miljukova. He said little of the girl, except that she was not very young and was very poor; she was free from scandal, however, and she loved him deeply. He hoped the marriage would be happy; and he asked the father's blessing. The father's letter showed an enthusiasm the son's lacked.
