interest," remarked the prince, holding out the instrument to Fisher, who took it and examined it carefully. "A butcher's cleaver that has done butcher's work."
"It was certainly the instrument of the crime," assented Fisher, in a low voice.
Brain was staring at the dull blue gleam of the ax head with fierce and fascinated eyes. "I don't understand you," he said. "There is no—there are no marks on it."
"It has shed no blood," answered Fisher, "but for all that it has committed a crime. This is as near as the criminal came to the crime when he committed it."
"What do you mean?"
"He was not there when he did it," explained Fisher. "It's a poor sort of murderer who can't murder people when he isn't there."
"You seem to be talking merely for the sake of mystification," said Brain. "If you have any practical advice to give you might as well make it intelligible."
"The only practical advice I can suggest," said Fisher, thoughtfully, "is a little research into local topography and nomenclature. They say there used to be a Mr. Prior, who had a farm in this neighborhood. I think some details about the domestic life of the late Mr. Prior would throw a light on this terrible business."
"And you have nothing more immediate than your topography to offer," said Brain, with a sneer, "to help me avenge my friend?"
"Well," said Fisher, "I should find out the truth about the Hole in the Wall."

That night, at the close of a stormy twilight and under a strong west wind that followed the breaking of the frost, Leonard Crane was wending his way in a wild rotatory walk round and round the high, continuous wall that inclosed the little wood. He was driven by a desperate idea of solving for himself the riddle that had clouded his reputation and already even threatened his liberty. The police authorities, now in charge of the inquiry, had not arrested him, but he knew well enough that if he tried to move far afield he would be instantly arrested. Horne Fisher's fragmentary hints, though he had refused to expand them as yet, had stirred the artistic temperament of the architect to a sort of wild analysis, and he was resolved to read the hieroglyph upside down and every way until it made sense. If it was something connected with a hole in the wall he would find the hole in the wall; but, as a matter of fact, he was unable to find the faintest crack in the wall. His professional knowledge told him that the masonry was all of one workmanship and one date, and, except for the regular entrance, which threw no light on the mystery, he found nothing suggesting any sort of hiding place or means of escape. Walking a narrow path between the winding wall and the wild eastward bend and sweep of the gray and feathery trees, seeing shifting gleams of a lost sunset winking almost like lightning as the clouds of tempest scudded across the sky and mingling with the first faint blue light from a slowly strengthened moon behind him, he began to feel his head going round as his heels were going round and round the blind recurrent barrier. He had thoughts on the border of thought; fancies about a fourth dimension which was itself a hole to hide anything, of seeing everything from a new angle out of a new window in the senses; or of some mystical light and transparency, like the new rays of chemistry, in which he could see Bulmer's body, horrible and glaring, floating in a lurid halo over the woods and the wall. He was haunted also with the hint, which somehow seemed to be equally horrifying, that it all had something to do with Mr. Prior. There seemed even to be something creepy in the fact that he was always respectfully referred to as Mr. Prior, and that it was in the domestic life of the dead farmer that he had been bidden to seek the seed of these dreadful things. As a matter of fact, he had found that no local inquiries had revealed anything at all about the Prior family.
The moonlight had broadened and brightened, the wind had driven off the clouds and itself died fitfully away, when he came round again to the artificial lake in front of the house. For some reason it looked a very artificial lake; indeed, the whole scene was like a classical landscape with a touch of Watteau; the Palladian facade of the house pale in the moon, and the same silver touching the very pagan and naked marble nymph in the middle of the pond. Rather to his surprise, he found another figure there beside the statue, sitting almost equally motionless; and the same silver pencil traced the wrinkled brow and patient face of Horne Fisher, still dressed as a hermit and apparently practicing something of the solitude of a hermit. Nevertheless, he looked up at Leonard Crane and smiled, almost as if he had expected him.
"Look here," said Crane, planting himself in front of him, "can you tell me anything about this business?"
"I shall soon have to tell everybody everything about it," replied Fisher, "but I've no objection to telling you something first. But, to begin with, will you tell me something? What really happened when you met Bulmer this morning? You did throw away your sword, but you didn't kill him."
"I didn't kill him because I threw away my sword," said the other. "I did it on purpose—or I'm not sure what might have happened."
After a pause he went on, quietly: "The late Lord Bulmer was a very breezy gentleman, extremely breezy. He was very genial with his inferiors, and would have his lawyer and his architect staying in his house for all sorts of holidays and amusements. But there was another side to him, which they found out when they tried to be his equals. When I told him that his sister and I were engaged, something happened which I simply can't and won't describe. It seemed to me like some monstrous upheaval of madness. But I suppose the truth is painfully simple. There is such a thing as the coarseness of a gentleman. And it is the most horrible thing in humanity."
"I know," said Fisher. "The Renaissance nobles of the Tudor time were like that."
"It is odd that you should say that," Crane went on. "For while we were talking there came on me a curious feeling that we were repeating some scene of the past, and that I was really some outlaw, found in the woods like Robin Hood, and that he had really stepped in all his plumes and purple out of the picture frame of the ancestral portrait. Anyhow, he was the man in possession, and he neither feared God nor regarded man. I defied him, of course, and walked away. I might really have killed him if I had not walked away."
"Yes," said Fisher, nodding, "his ancestor was in possession and he was in possession, and this is the end of the story. It all fits in."
"Fits in with what?" cried his companion, with sudden impatience. "I can't make head or tail of it. You tell me to look for the secret in the hole in the wall, but I can't find any hole in the wall."
"There isn't any," said Fisher. "That's the secret." After reflecting a moment, he added: "Unless you call it a hole in the wall of the world. Look here; I'll tell you if you like, but I'm afraid it involves an introduction. You've got to understand one of the tricks of the modern mind, a tendency that most people obey without noticing it. In the village or suburb outside there's an inn with the sign of St. George and the Dragon. Now suppose I went about telling everybody that this was only a corruption of King George and the Dragoon. Scores of people would believe it, without any inquiry, from a vague feeling that it's probable because it's prosaic. It turns something romantic and legendary into something recent and ordinary. And that somehow makes it sound rational, though it is unsupported by reason. Of course some people would have the sense to remember having seen St. George in old Italian pictures and French romances, but a good many wouldn't think about it at all. They would just swallow the skepticism because it was skepticism. Modern intelligence won't accept anything on authority. But it will accept anything without authority. That's exactly what has happened here.
"When some critic or other chose to say that Prior's Park was not a priory, but was named after some quite modern man named Prior, nobody really tested the theory at all. It never occurred to anybody repeating the story to ask if there was any Mr. Prior, if anybody had ever seen him or heard of him. As a matter of fact, it was a priory, and shared the
