"Too bad you didn't notice the handwriting-that is, whether it seemed to be a man's or a woman's."
"I think, under the circumstances, I would be excused for omitting that," was the reply.
"You said you heard something that you thought must be a rat," went on The Thinking Machine. "What was this?"
"I don't know."
"Any squeak about it?"
"No, not that I noticed."
"Five years since the house was occupied," mused the scientist. "How far away is the water?"
"The place overlooks the water, but it's a steep climb of three hundred yards from the water to the house."
That seemed to satisfy The Thinking Machine as to what actually happened.
"When you went over the house in daylight, did you notice if any of the mirrors were dusty?" he asked.
"I should presume that all were," was the reply. "There's no reason why they should have been otherwise."
"But you didn't notice particularly that some were not dusty?" the scientist insisted.
"No. I merely noticed that they were there."
The Thinking Machine sat for a long time squinting at the ceiling, then asked, abruptly:
"Have you seen Mr. Weston, the owner?"
"No."
"See him and find out what he has to say about the place, the murder, the jewels, and all that. It would be rather a queer state of affairs if, say, a fortune in jewels should be concealed somewhere about the place, wouldn't it?"
"It would," said Hatch. "It would."
"Who is Miss Katherine Everard?"
"Daughter of a banker here, Curtis Everard. Was a reigning belle at Newport for two seasons. She is now in Europe, I think, buying a trousseau, possibly."
"Find out all about her, and what Weston has to say, then come back here," said The Thinking Machine, as if in conclusion. "Oh, by the way," he added, "look up something of the family history of the Westons. How many heirs were there? Who are they? How much did each one get? All those things. That's all."
Hatch went out, far more composed and quiet than when he entered, and began the work of finding out those things The Thinking Machine had asked for, confident now that there would be a solution of the mystery.
That night the flaming phantom played new pranks. The town constable, backed by half a dozen villagers, descended upon the place at midnight, to be met in the yard by the apparition in person. Again the dagger was seen; again the ghostly laughter and the awful cry were heard.
"Surrender or I'll shoot," shouted the constable, nervously.
A laugh was the answer, and the constable felt something warm spatter in his face. Others in the party felt it, too, and wiped their faces and hands. By the light of the feeble lanterns they carried they examined their handkerchiefs and hands. Then the party fled in awful disorder.
The warmth they had felt was the warmth of blood-red blood, freshly drawn.
III.
Hatch found Ernest Weston at luncheon with another gentleman at one o'clock that day. This other gentleman was introduced to Hatch as George Weston, a cousin. Hatch instantly remembered George Weston for certain eccentric exploits at Newport a season or so before; and also as one of the heirs of the original Weston estate.
Hatch thought he remembered, too, that at the time Miss Everard had been so prominent socially at Newport George Weston had been her most ardent suitor. It was rumored that there would have been an engagement between them, but her father objected. Hatch looked at him curiously; his face was clearly a dissipated one, yet there was about him the unmistakable polish and gentility of the well-bred man of society.
Hatch knew Ernest Weston as Weston knew Hatch; they had met frequently in the ten years Hatch had been a newspaper reporter, and Weston had been courteous to him always. The reporter was in doubt as to whether to bring up the subject on which he had sought out Ernest Weston, but the broker brought it up himself, smilingly.
"Well, what is it this time?" he asked, genially. "The ghost down on the South Shore, or my forth-coming marriage?"
"Both," replied Hatch.
Weston talked freely of his engagement to Miss Everard, which he said was to have been announced in another week, at which time she was due to return to America from Europe. The marriage was to be three or four months later, the exact date had not been set.
"And I suppose the country place was being put in order as a Summer residence?" the reporter asked.
"Yes. I had intended to make some repairs and changes there, and furnish it, but now I understand that a ghost has taken a hand in the matter and has delayed it. Have you heard much about this ghost story?" he asked, and there was a slight smile on his face.
"I have seen the ghost," Hatch answered.
"You have?" demanded the broker.
George Weston echoed the words and leaned forward, with a new interest in his eyes, to listen. Hatch told them what had happened in the haunted house-all of it. They listened with the keenest interest, one as eager as the other.
"By George!" exclaimed the broker, when Hatch had finished. "How do you account for it?"
"I don't," said Hatch, flatly. "I can offer no possible solution. I am not a child to be tricked by the ordinary illusion, nor am I of the temperament which imagines things, but I can offer no explanation of this."
"It must be a trick of some sort," said George Weston.
"I was positive of that," said Hatch, "but if it is a trick, it is the cleverest I ever saw."
The conversation drifted on to the old story of missing jewels and a tragedy in the house fifty years before. Now Hatch was asking questions by direction of The Thinking Machine; he himself hardly saw their purport, but he asked them.
"Well, the full story of that affair, the tragedy there, would open up an old chapter in our family which is nothing to be ashamed of, of course," said the broker, frankly; "still it is something we have not paid much attention to for many years. Perhaps George here knows it better than I do. His mother, then a bride, heard the recital of the story from my grandmother."
Ernest Weston and Hatch looked inquiringly at George Weston, who lighted a fresh cigarette and leaned over the table toward them. He was an excellent talker.
"I've heard my mother tell of it, but it was a long time ago," he began. "It seems, though, as I remember it, that my great-grandfather, who built the house, was a wealthy man, as fortunes went in those days, worth probably a million dollars.
"A part of this fortune, say about one hundred thousand dollars, was in jewels, which had come with the family from England. Many of those pieces would be of far greater value now than they were then, because of their antiquity. It was only on state occasions, I might say, when these were worn, say, once a year.
"Between times the problem of keeping them safely was a difficult one, it appeared. This was before the time of safety deposit vaults. My grandfather conceived the idea of hiding the jewels in the old place down on the South Shore, instead of keeping them in the house he had in Boston. He took them there accordingly.
"At this time one was compelled to travel down the South Shore, below Cohasset anyway, by stagecoach. My grandfather's family was then in the city, as it was Winter, so he made the trip alone. He planned to reach there at night, so as not to attract attention to himself, to hide the jewels about the house, and leave that same night for Boston again by a relay of horses he had arranged for. Just what happened after he left the stagecoach, below Cohasset, no one ever knew except by surmise."
