“Naturally, I viewed the advent of the new Mrs. Keene with some jealousy. But there was no occasion. She was a good, kindly woman who showed from the first that she meant to do her duty by her little step-daughter. And her own child, Barbara, equally disarmed our jealousy. A quiet, rather reserved little girl, but very clever and quick-witted, she not only accepted me at once with the frankest friendliness but, with a curious tactfulness for such a young girl, devoted herself to my little friend, Stella Keene, without in the least attempting to oust me from my position. In effect, we three young people became a most united and harmonious little coterie in which our respective positions were duly recognized. I was the head of the firm, so to speak, Stella was my adopted sister, and Barbara was the ally of us both.

“So our relations continued as the years passed; but presently the passing years began to take toll of our seniors. My father was the first to go. Then followed Mr. Keene, and after a few more years, Barbara’s mother. By the time my twenty-fifth birthday came round, we were all orphans.”

“What were your respective ages then?” Thorndyke asked.

Rather surprised at the question, I paused to make a calculation.

“My own age,” I replied, “was, as I have said, twenty-five. Barbara would then be twenty-two and Stella sixteen.”

Thorndyke made a note of my answer and I proceeded:

“The death of our elders made no appreciable difference in our way of living. My father had left me a modest competence and the two girls were fairly provided for. The houses that we occupied were beyond our needs, reduced as we were in numbers and we discussed the question of sharing a house. But, of course, the girls were not really my sisters and the scheme was eventually rejected as rather too unconventional; so we continued to live in our respective houses.”

“Was there any trustee for the girls?” Thorndyke asked.

“Yes, Mr. Brodribb. The bulk of the property was, I believe, vested in Stella, but, for reasons which I shall come to in a moment, there was a provision that, in the event of her death, it should revert to Barbara.”

“On account, I presume, of the tendency to consumption?”
