Mary Roberts Rinehart,
The Circular Staircase
“ 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. ”
