Ah! Was it so? His sweetheart dead! In that far-away country! Then, perhaps, when he recovered from this he would marry Luigia, who had the most wonderful hair in the world, and was so fair, as to seem as though she had come from the place where his, Signor O'Donnell's, wife had come from. Luigia was a good girl, and not like others, and if the Signor did marry her, she would make him a good wife; for having been poor she would know the value of his money. But the poor Signor who had gone away that day was in no humour to think of marriage now. Only of death and the grave. Did Signor O'Donnell know of the sweetheart of the other? Yes. And she was also fair, like the Signora and Luigia? No; dark. Ah, how strange. How incomprehensible. Here in this country they were nearly all dark, and when a fair woman came among them, no dark woman had a chance against her. But if what people said was true, there were the dark and the fair in the place from which the Signora came, and a man could choose, after his liking, the dark or the fair. Yet the poor Signor, who had lost his sweetheart, had chosen, in his own country, a dark woman for a sweetheart, and here, for a sweetheart, a fair woman. He was fickle in love. Had Signor O'Donnell noticed that Luigia had a strong resemblance to the Signora? Luigia was a good girl. God keep her from harm. Eugene came back and told Nellie that Lavirotte had suddenly left for London, without, as far as he knew, saying a word to anyone. According to what his landlady had said, Lavirotte must have gone straight home, and gone from his lodgings to the railway station. What an odd fellow he was, not to say a word, not to take a portmanteau or even hand-bag with him, but dash off across Europe just as they had seen him last. "You know, Nellie," said Eugene, putting his arm round his wife's waist, "I often told you I thought there was a screw loose in Lavirotte, and every day that goes over confirms me more and more in this belief. It is a curious fact that some great-great-grandfather or other had a mania for mania, and wrote a book about something or other connected with the mind. Of late Lavirotte has said a lot to me about the injudiciousness of trusting to a voice for a living. He has told me, what is quite true, that until a voice has been tested on the stage and in front of an audience, no one can tell what it is going to be. It is just like an unacted play. It may be worth five pounds a week, or it may be worth five hundred. Then he has said to me that he thinks his natural bent was towards medicine, and only that he had given up so much time now to the cultivation of his voice, he would certainly, if he had the money, become a doctor.
