"If you had made that discovery yesterday, Archie, before it had been effected, you might have done some good. Of course, it is quite clear to-day. A child could see that," she added impatiently. "I wish you wouldn't interrupt me with such wonderful deductions, dear. I dare say they are clever, but—"

Letitia's irritable tone hurt me. The pain of these incidents had been temporarily deadened by my Sherlock Holmes demeanor. Still, I was bound to confess that, as Letitia pointed out, the case did seem simple.

"Mrs. Archer seemed furious with me," Letitia said querulously. "The more we discovered that our troubles coincided, the angrier she grew. At one time"—and here Letitia flushed—"she seemed to be positively suspicious. She had noticed the constant communication between the two cooks by means of the dumb-waiter."

"The dumb-waiter seems to be a sort of hyphen, connecting devils," I interpolated epigrammatically.

"Don't be witty, Archie. Don't even try to be witty, please. As I think of Mrs. Archer's attitude, when she first entered, I feel humiliated. She admitted that she thought Rosie was here. Rosie was the cook. And it was not until I told her of Nellie's departure, and the loss I had sustained, that her manner changed. When I mentioned the fact that I had missed a diamond ring, six silver spoons, a gold whisky flask, and a comb with pearls and turquoises, she really heaved a sigh of relief. She said, 'Oh, I'm so glad, Mrs. Fairfax—' and then she checked herself, and added that she was glad the case was not complicated."

"I'll see her husband, and demand a written apology," I declared indignantly.

"You are always too late, dear," said Letitia quietly. "Mrs. Archer apologized profusely. She told me that her husband had always been suspicious of people who live in apartments—since Dr. Parkhurst had bungled up New York. She was very nice. She said she could see at once that we were quite respectable."

"How insulting!" I cried.

"Insulting!" echoed Letitia. "If she had said she could see that we were not quite respectable, then it would have been insulting. Perhaps I am describing the scene badly. At any rate, though it may sound insulting to you, Archie, it didn't to me. She didn't say it in precisely the terms I have used. Mrs. Archer is a very pleasant person. We grew quite chummy. We added up our losses. Rosie had taken three hundred and thirty-seven dollars' worth, and Nellie had gone off with at least seven hundred and fifty dollars' worth. She admitted that I was twice as aggrieved as she was. And I must say, Archie, I couldn't help feeling pleased that I had the best of her."

"The best of her, Letitia? You mean the worst of her."
