“Yes, exactly. But you couldn’t find any such person in relation to Miss Stableford?”
“No, we couldn’t.”
“Well, here’s a suggestion. I tell you frankly, I don’t think it could be substantiated in court. I don’t give it to you as a certain deduction—it’s only a suggestion. The only mystery you can learn of in connection with Miss Stableford is the mystery of her birth.”
“Yes, that is so.”
“Well, now, it’s pretty certain that the murderer of Miss Stableford was a woman—this Mrs. Garnett.”
“Granted. What next?”
The barrister paused. “How old was Mrs. Garnett? The hotel people say middle-aged, forty to forty-five.”
“Old enough to be Miss Stableford’s mother?”
“Yes, the girl was a bit short of twenty-one.”
“Well, Yardley, suppose you’ve got it now?”
