Kennedy looked at the mysterious opening some time, as if trying to fathom the mystery.
"Let's go down and explore it," I suggested, taking a step toward the ladder.
Kennedy reached out and pulled me back. Then without a word he pressed the little lever and the door closed.
"I think we'd better wait a while, Walter," he decided. "I would rather hear Aunt Tabby's haunts myself."
He carefully went over not only the rest of the house but the grounds about it, without discovering anything.
Aunt Tabby, with true country hospitality, seemed unable to receive guests without feeding them, and, although we had had a big dinner at a famous road-house on the way out, still none of us could find it in our hearts to refuse her hospitality. Even that diversion, however, did not prevent us from talking of nothing else but the strange noises, and I think, as we waited, we all got into the frame of mind which would have manufactured them even if there had been none.
We were sitting about the room when suddenly the most weird and uncanny rappings began. Rusty was on his feet in a moment, barking like mad. We looked from one to another.
It was impossible to tell where the noises came from, or even to describe them. They were certainly not ghostly rappings. In fact, they sounded more like some twentieth century piece of machinery.
We listened a moment, then Kennedy walked over to the fireplace. "You can explore it with me now, Walter," he said quietly, touching the lever and opening the panel which disclosed the ladder.
He started down the ladder and I followed closely. Elaine was about to join us, when Kennedy paused on the topmost round and looked up at her.
