For one night, however, Mr. Jamieson preferred to watch alone.
Apparently nothing occurred.
The detective sat in absolute darkness on the lower step of the stairs, dozing, he said afterwards, now and then.
Nothing could pass him in either direction, and the door in the morning remained as securely fastened as it had been the night before.
And yet one of the most inexplicable occurrences of the whole affair took place that very night.
Liddy came to my room on Sunday morning with a face as long as the moral law.
She laid out my things as usual, but I missed her customary garrulousness.
I was not regaled with the new cook's extravagance as to eggs, and she even forbore to mention "that Jamieson," on whose arrival she had looked with silent disfavor.
"What's the matter, Liddy?" I asked at last.
"Didn't you sleep last night?"
"No, ma'm," she said stiffly.
"Did you have two cups of coffee at your dinner?" I inquired.
"No, ma'm," indignantly.
I sat up and almost upset my hot water—I always take a cup of hot water with a pinch of salt, before I get up. It tones the stomach.
"Liddy Allen," I said, "stop combing that switch and tell me what is wrong with you."
Liddy heaved a sigh.
"Girl and woman," she said, "I've been with you twenty-five years, Miss Rachel, through good temper and bad—" the idea! and what I have taken from her in the way of sulks!—"but I guess I can't stand it any longer.
My trunk's packed."
"Who packed it?" I asked, expecting from her tone to be told she had wakened to find it done by some ghostly hand.
"I did; Miss Rachel, you won't believe me when I tell you this house is haunted.
Who was it fell down the clothes chute?
Who was it scared Miss Louise almost into her grave?"
"I'm doing my best to find out," I said.
"What in the world are you driving at?"
She drew a long breath.
"There is a hole in the trunk-room wall, dug out since last night.
It's big enough to put your head in, and the plaster's all over the place."
"Nonsense!" I said.
"Plaster is always falling."
But Liddy clenched that.
"Just ask Alex," she said.
"When he put the new cook's trunk there last night the wall was as smooth as this.
This morning it's dug out, and there's plaster on the cook's trunk. Miss Rachel, you can get a dozen detectives and put one on every stair in the house, and you'll never catch anything.
There's some things you can't handcuff."
Liddy was right.
As soon as I could, I went up to the trunk-room, which was directly over my bedroom.
The plan of the upper story of the house was like that of the second floor, in the main.
One end, however, over the east wing, had been left only roughly finished, the intention having been to convert it into a ball-room at some future time.
The maids' rooms, trunk-room, and various store-rooms, including a large airy linen-room, opened from a long corridor, like that on the second floor.
And in the trunk-room, as Liddy had said, was a fresh break in the plaster.
Not only in the plaster, but through the lathing, the aperture extended.
I reached into the opening, and three feet away, perhaps, I could touch the bricks of the partition wall.
For some reason, the architect, in building the house, had left a space there that struck me, even in the surprise of the discovery, as an excellent place for a conflagration to gain headway.
"You are sure the hole was not here yesterday?" I asked Liddy, whose expression was a mixture of satisfaction and alarm.
In answer she pointed to the new cook's trunk—that necessary adjunct of the migratory domestic.
The top was covered with fine white plaster, as was the floor.
But there were no large pieces of mortar lying around—no bits of lathing.
When I mentioned this to Liddy she merely raised her eyebrows.
Being quite confident that the gap was of unholy origin, she did not concern herself with such trifles as a bit of mortar and lath.
No doubt they were even then heaped neatly on a gravestone in the Casanova churchyard!
