"You don't believe in me," she said, "and your sister does. Why do you doubt my word?"

I had rapidly come to the conclusion that the only possible attitude to adopt toward the strange nature with which I had to deal was that of direct plainness.

"My sister, being a woman, is naturally guided and influenced by her intuitions," I said; "I, not only as a man but as a lawyer, undertaking a serious case, am obliged to depend upon the facts which I observe for myself, and the facts which I gather from the statements of my client."

"But you don't believe the facts I state," said Janet and now her tone acquired a petulance, as of a pouting child.

I was annoyed at this, and began to think that I had to deal with a dozen different natures in one, and could never know which would appear uppermost. I returned to my inquisition.

"Why do you think Charlotte could not have done this thing?" I asked, although I had asked this before.

"Because she had no motive," said Janet briefly.

This was surprising in its implication, but I went doggedly on:

"Who, then, had a motive?"
