David's close interest in her story pleased the girl. Such a nice young man he was! Perhaps he might call again some evening.
"My missus wasn't quite right the rest of her time, I don't think," she went on. "She wandered about the flat, restless as a strange kitten, singing bits of songs, and she had a sweet soprano voice, I'm sure, that pierced you through when she screamed out the high notes. She didn't go to the theater any more, after the letter. The next day she comes to me in the kitchen, singing and chuckling to herself, and she says to me: 'What are you doing here?' says she. 'How do you mean, mum?' says I. 'Listen, Sarah,' says she, putting her face quite close to mine, 'you shouldn't be here, this is not a place for a decent girl like you. You are to understand that I am not married. I told you that I was; but it was a lie. I have a child; but I am not married,' and she ran off, laughing again to herself, as wild as a bird."
"No, not that!" interrupted David, for the outspoken revelation hurt him. "It was not so much that which I wished to hear. Let us talk of the letter and the man. You never saw the letter again? You can't think what your mistress may have done with it?"
"No, I never saw it again," said Sarah, "nor I can't think where she may have put it, unless she tore it up. There's only one queer thing which I can call to mind, and that is, that during the afternoon of the day before she died, I went out to buy some soda, and when I came back I found her standing on a chair, hanging up one of the pictures in the long corridor. I wondered at the time whether it had fallen down or what, though I didn't say anything. But now I come to think of it--"
David thought to himself: "She was then hiding the marriage and birth certificates which Miss L'Estrange afterward saw when the picture fell. She was reluctant to destroy them, and yet wished to screen the man, having in her mind the purpose to take her own life. The man's photograph and the fatal letter from him were not hidden in the picture, but somewhere else, perhaps. I must search every cranny."
"Of course," he said aloud, "you could easily identify her husband if he was shown to you again?"
"Oh, rather, sir," Sarah answered, "I've seen him dozens of times. He used to come to the flat anyway twice a week, though sometimes he would be away for a goodish stretch, mostly in Paris."
