tonight," she said. "He was in a great hurry. Wouldn't even stop for a bite of breakfast."
"That is his way," I replied, "when engrossed in a particularly interesting investigation. He will probably neither eat nor drink until the mystery has been solved."
"And will that be soon?"
"I believe it will."
"Just what is your opinion, Mr. Evans, of the things you saw last night?"
"I'm afraid," I replied, "that my opinion at this time is not of much value. Frankly, I have been mystified. I have theories, of course, but they are, after all, only theories."
"Do you believe it was the ghost of Uncle Gordon that we saw in the living room last night?"
"I don't believe in ghosts."
"Then what was it? What could have caused it? What could have caused doors to lock and unlock, to open and close without the touch of human hands? What could have caused the intense cold—the poker to creep across the floor as if it were alive? What drove my dog mad with fear?"
"The dog," I replied, "showed symptoms of hydrophobia."
"That is what Dr. Dorp thought, although he was not sure. He took the carcass with him, wrapped in a sheet, for examination."
"Then his opinion confirms that of Dr. Graves."
"I don't see how poor Sandy could have gotten it," she said. "He hasn't been near any other animal, and I understand he would have to be scratched or bitten by one to become infected."
"The examination will show whether or not he had hydrophobia, and I hope he hadn't," I replied, "for a very personal reason. Just how he contracted it, of course, may never be known."
"For your sake, I too hope that he didn't have it. You are in grave danger, are you not, from that bite?"
"Not so bad as all that. A comparatively short time ago it was the equivalent of a death warrant to be bitten by a rabid animal. Modern science, however, has made death from hydrophobia a rarity when treatment is administered in time."
THE remainder of the day was spent quite pleasantly, strolling about the grounds and on the white,
foam-edged beach, or lolling on the large, confortable porch.
We had dinner at six, and I was enjoying a cigar in the swing shortly thereafter, when I heard the throb of a motor in the driveway and the big car of Dr. Dorp came into view.
He drove up to the curb, and I saw that he had four men with him. Each was carrying a large package covered with khaki. The packages were placed on the porch, and the doctor presented his four companions, as Mr. Easton, civil engineer, Mr. Brandon, electrical engineer, and Messrs. Hogan and Rafferty, detectives. At a sign from the doctor, the two detectives immediately strolled out into the shrubbery.
"We're going to make a few preparations for the show this evening," he said, addressing me. "Want to come along?"
"Of course."
"All right. Each man grab a bundle. We haven't much time before dark."
I took up one of the khaki wrapped packages, which was far from light, and each other man did likewise. The doctor led the way around the house, and down to the beach.
Directly behind the house we unwrapped two of the packages. One proved to be a set of surveyor's instruments which the civil engineer quickly assembled. The other looked very much like a radio set with its loop aerials and dials, although there was no speaker or head phone with it. The radio set was placed on a small folding table, and Mr. Easton sighted from that point, while I acted as roadman and Mr. Brandon as chainman. We measured off a distance of two thousand feet in a straight line along the beach, the doctor following with the other package. At that point, the other radio-like machine was assembled and placed on a folding table. We left Mr. Brandon with this machine, and went back to the first one.
"Now, Evans," said my friend. "You and Mr. Easton go back to the house and keep Miss Van Loan company. As soon as it begins to get dark go into the living room and occupy the same positions as last night. Mr. Easton has a false beard with him, and will be disguised to look like me. Caution Miss Van Loan, when she is inside the house, to address Mr. Easton by my name. Do not, under any circumstances, tell her this while you are in the house. When you hear my motor racing outside, come out. Mr. Easton will remain. Rafferty will then go in to take your place. Is everything clear?"
"Perfectly."
We found Miss Van Loan on the porch, and I whispered our plans to her while Easton adjusted his whiskers. He was about the same build and height as the doctor, and thus disguised, bore considerable resemblance to him.
We chatted on the porch until dusk, then went into the living room and took our seats. Presently the door opened and closed as on the night before. Then the lights went out. Hearing a rustling sound near the door, I looked, and saw the gleaming print of a human foot forming on the carpet. In a moment another had formed in front of it while the rustling sound continued. The first footprint disappeared and a third formed in front of the second. It was as if some invisible entity were walking toward the center of the room, leaving luminous tracks which disappeared each time a foot was lifted.
The footprints stopped, and drew together, side by side, in the center of the room. Then there was a slight thump, and a wispy form, similar to the one we had seen the night before, began to materialize while the two footprints slowly faded. The thing reached a height of more than six feet, wabbling this way and that as if scarcely able to support its own weight, while the horrible odor we had noticed the night before permeated the room.
