“But there are other ghosts—if you like to term them so—that are more troublesome”

“I don’t think so, sir,” he said. “At any rate, I shouldn’t trouble myself about it.” His voice sounded so strange, I thought, and there was such an odd, furtive look in his eyes, that I became curious, and walking across the hall, arrived on the other side, just in time to see the elevator come slowly and softly down.

To my astonishment there was no one in it.

“How’s that happened?” I remarked. “No one called it, and had they done so we must have seen them.”

“I can’t say, sir,” the porter replied, looking very uneasy.

“Well, it’s certainly rather odd,” I ejaculated. “Anyhow, it’s chosen to come down at a very convenient moment.” And, getting in, I went up.

The following night I returned late, and entered the vestibule of the hotel just as the elevator stopped.

“Does it come down at the same time every night?” I asked the porter.
