It was not possible. Such things did not happen these unromantic days to musical celebrities. She had written that on Monday night she would sing in _La Bohème_ and on Wednesday, _Faust_. She had since vanished, vanished as completely as though she had taken wings and flown away. It was unreal. She had left the apartment in the Avenue de Wagram on Saturday afternoon, and nothing had been seen or heard of her since. At the last moment they had had to find a substitute for her part in the Puccini opera. The maid testified that her mistress had gone on an errand of mercy. She had not mentioned where, but she had said that she would return in time to dress for dinner, which proved conclusively that something out of the ordinary had befallen her.
The automobile that had carried her away had not been her own, and the chauffeur was unknown. None of the directors at the Opera had been notified of any change in the singer's plans. She had disappeared, and they were deeply concerned. Singers were generally erratic, full of sudden indispositions, unaccountable whims; but the Signorina da Toscana was one in a thousand. She never broke an engagement. If she was ill she said so at once; she never left them in doubt until the last moment. Indecision was not one of her characteristics. She was as reliable as the sun. If the directors did not hear definitely from her by noon to-day, they would have to find another Marguerite.
The police began to move, and they stirred up some curious bits of information. A man had tried to bribe the singer's chauffeur, while she was singing at the Austrian ambassador's. The chauffeur was able to describe the stranger with some accuracy. Then came the bewildering episode in the apartment: the pistol-shot, the flight of the man, the astonished concierge to whom the beautiful American would offer no explanations. The man (who tallied with the description given by the chauffeur) had obtained entrance under false representations. He claimed to be an emissary with important instructions from the Opera. There was nothing unusual in this; messengers came at all hours, and seldom the same one twice; so the concierge's suspicions had not been aroused. Another item. A tall handsome Italian had called at eleven o'clock Saturday morning, but the signorina had sent down word that she could not see him. The maid recalled that her mistress had intended to dine that night with the Italian gentleman. His name she did not know, having been with the signorina but two weeks.
