But he said to keep on hoping, that it was the best news we had had. And in the meantime, consumed with anxiety as we were, things were happening at the house in rapid succession.
We had one peaceful day—then Liddy took sick in the night. I went in when I heard her groaning, and found her with a hot-water bottle to her face, and her right cheek swollen until it was glassy.
“Toothache?” I asked, not too gently. “You deserve it. A woman of your age, who would rather go around with an exposed nerve in her head than have the tooth pulled! It would be over in a moment.”
“So would hanging,” Liddy protested, from behind the hot-water bottle.
I was hunting around for cotton and laudanum.
“You have a tooth just like it yourself, Miss Rachel,” she whimpered. “And I’m sure Doctor Boyle’s been trying to take it out for years.”
There was no laudanum, and Liddy made a terrible fuss when I proposed carbolic acid, just because I had put too much on the cotton once and burned her mouth. I’m sure it never did her any permanent harm; indeed, the doctor said afterward that living on liquid diet had been a splendid rest for her stomach. But she would have none of the acid, and she kept me awake groaning, so at last I got up and went to Gertrude’s door. To my surprise, it was locked.
I went around by the hall and into her bedroom that way. The bed was turned down, and her dressing-gown and night-dress lay ready in the little room next, but Gertrude was not there. She had not undressed.
I don’t know what terrible thoughts came to me in the minute I stood there. Through the door I could hear Liddy grumbling, with a squeal now and then when the pain stabbed harder. Then, automatically, I got the laudanum and went back to her.
It was fully a half-hour before Liddy’s groans subsided. At intervals I went to the door into the hall and looked out, but I saw and heard nothing suspicious. Finally, when Liddy had dropped into a doze, I even ventured as far as the head of the circular staircase, but there floated up to me only the even breathing of Winters, the night detective, sleeping just inside the entry. And then, far off, I heard the rapping noise that had lured Louise down the staircase that other night, two weeks before. It was over my head, and very faint—three or four short muffled taps, a pause, and then again, stealthily repeated.
