“He knew there would be a thaw,” observed the prince. “He went out skating quite early on purpose. Did he call out because he landed in the water, do you think?”

  Fisher looked puzzled. “Bulmer was the last man to bellow like that because he got his boots wet. And that’s all he could do here; the water would hardly come up to the calf of a man of his size. You can see the flat weeds on the floor of the lake, as if it were through a thin pane of glass. No, if Bulmer had only broken the ice he wouldn’t have said much at the moment, though possibly a good deal afterward. We should have found him stamping and damning up and down this path, and calling for clean boots.”

  “Let us hope we shall find him as happily employed,” remarked the diplomatist. “In that case the voice must have come out of the wood.”

  “I’ll swear it didn’t come out of the house,” said Fisher; and the two disappeared together into the twilight of wintry trees.

  The plantation stood dark against the fiery colors of sunrise, a black fringe having that feathery appearance which makes trees when they are bare the very reverse of rugged. Hours and hours afterward, when the same dense, but delicate, margin was dark against the greenish colors opposite the sunset, the search thus begun at sunrise had not come to an end. By successive stages, and to slowly gathering groups of the company, it became apparent that the most extraordinary of all gaps had appeared in the party; the guests could find no trace of their host anywhere. The servants reported that his bed had been slept in and his skates and his fancy costume were gone, as if he had risen early for the purpose he had himself avowed. But from the top of the house to the bottom, from the walls round the park to the pond in the center, there was no trace of Lord Bulmer, dead or alive. Horne Fisher realized that a chilling premonition had already prevented him from expecting to find the man alive. But his bald brow was wrinkled over an entirely new and unnatural problem, in not finding the man at all.

  He considered the possibility of Bulmer having gone off of his own accord, for some reason; but after fully weighing it he finally dismissed it. It was inconsistent with the unmistakable voice heard at daybreak, and with many other practical obstacles. There was only one gateway in the ancient and lofty wall round the small park; the lodge keeper kept it locked till late in the morning, and the lodge keeper had seen no one pass. Fisher was fairly sure that he had before him a mathematical problem in an inclosed space. His instinct had been from the first so attuned to the tragedy that it would have been almost a relief to him to find the corpse. He would have been grieved, but not horrified, to come on the nobleman’s body dangling from one of his own trees as from a gibbet, or floating in his own pool like a pallid weed. What horrified him was to find nothing.

  He soon become conscious that he was not alone even in his most individual and isolated experiments. He often found a figure following him like his shadow, in silent and almost secret clearings in the plantation or outlying nooks and corners of the old wall. The dark-mustached mouth was as mute as the deep eyes were mobile, darting incessantly hither and thither, but it was clear that Brain of the Indian police had taken up the trail like an old hunter after a tiger. Seeing that he was the only personal friend of the vanished man, this seemed natural enough, and Fisher resolved to deal frankly with him.

  “This silence is rather a social strain,” he said. “May I break the ice by talking about the weather? — which, by the way, has already broken the ice. I know that breaking the ice might be a rather melancholy metaphor in this case.”

  “I don’t think so,” replied Brain, shortly. “I don’t fancy the ice had much to do with it. I don’t see how it could.”

  “What would you propose doing?” asked Fisher.

  “Well, we’ve sent for the authorities, of course, but I hope to find something out before they come,” replied the Anglo-Indian. “I can’t say I have much hope from police methods in this country. Too much red tape, habeas corpus and that sort of thing. What we want is to see that nobody bolts; the nearest we could get to it would be to collect the company and count them, so to speak. Nobody’s left lately, except that lawyer who was poking about for antiquities.”

  “Oh, he’s out of it; he left last night,” answered the other. “Eight hours after Bulmer’s chauffeur saw his lawyer off by the train I heard Bulmer’s own voice as plain as I hear yours now.”

  “I suppose you don’t believe in spirits?” said the man from India. After a pause he added: “There’s somebody else I should like to find, before we go after a fellow with an alibi in the Inner Temple. What’s become of that fellow in green — the architect dressed up as a forester? I haven’t seem him about.”

  Mr. Brain managed to secure his assembly of all the distracted company before the arrival of the police. But when he first began to comment once more on the young architect’s delay in putting in an appearance, he found himself in the presence of a minor mystery, and a psychological development of an entirely unexpected kind.

  Juliet Bray had confronted the catastrophe of her brother’s disappearance with a somber stoicism in which there was, perhaps, more paralysis than pain; but when the other question came to the surface she was both agitated and angry.

  “We don’t want to jump to any conclusions about anybody,” Brain was saying in his staccato style. “But we should like to know a little more about Mr. Crane. Nobody seems to know much about him, or where he comes from. And it seems a sort of coincidence that yesterday he actually crossed swords with poor Bulmer, and could have stuck him, too, since he showed himself the better swordsman. Of course, that may be an accident and couldn’t possibly be called a case against anybody; but then we haven’t the means to make a real case against anybody. Till the police come we are only a pack of very amateur sleuthhounds.”

  “And I think you’re a pack of snobs,” said Juliet. “Because Mr. Crane is a genius who’s made his own way, you try to suggest he’s a murderer without daring to say so. Because he wore a toy sword and happened to know how to use it, you want us to believe he used it like a bloodthirsty maniac for no reason in the world. And because he could have hit my brother and didn’t, you deduce that he did. That’s the sort of way you argue. And as for his having disappeared, you’re wrong in that as you are in everything else, for here he comes.”

  And, indeed, the green figure of the fictitious Robin Hood slowly detached itself from the gray background of the trees, and came toward them as she spoke.

  He approached the group slowly, but with composure; but he was decidedly pale, and the eyes of Brain and Fisher had already taken in one detail of the green-clad figure more clearly than all the rest. The horn still swung from his baldrick, but the sword was gone.

  Rather to the surprise of the company, Brain did not follow up the question thus suggested; but, while retaining an air of leading the inquiry, had also an appearance of changing the subject.

  “Now we’re all assembled,” he observed, quietly, “there is a question I want to ask to begin with. Did anybody here actually see Lord Bulmer this morning?”

  Leonard Crane turned his pale face round the circle of faces till he came to Juliet’s; then he compressed his lips a little and said:

  “Yes, I saw him.”

  “Was he alive and well?” asked Brain, quickly. “How was he dressed?”

  “He appeared exceedingly well,” replied Crane, with a curious intonation. “He was dressed as he was yesterday, in that purple costume copied from the portrait of his ancestor in the sixteenth century. He had his skates in his hand.”

  “And his sword at his side, I suppose,” added the questioner. “Where is your own sword, Mr. Crane?”

  “I threw it away.”

  In the singular silence that ensued, the train of thought in many minds became involuntarily a series of colored pictures.

  They had grown used to their fanciful garments looking more gay and gorgeous against the dark gray and streaky silver of the forest, so that the moving figures glowed like stained-glass saints walking. The effect had been more fitting because so many of them had idly parodied pontifical or monastic dress. But the most arresting attitude that remained in their memories had been anything but merely monastic; that of the moment when the figure in bright green and the other in vivid violet had for a moment made a silver cross of their crossing swords. Even when it was a jest it had been something of a drama; and it was a strange and sinister thought that in the gray daybreak the same figures in the same posture might have been repeated as a tragedy.

  “Did you quarrel with him?” asked Brain, suddenly.

  “Yes,” replied the immovable man in green. “Or he quarreled with me.”

  “Why did he quarrel with you?” asked the investigator; and Leonard Crane made no reply.

  Horne Fisher, curiously enough, had only given half his attention to this crucial cross-examination. His heavy-lidded eyes had languidly followed the figure of Prince Borodino, who at this stage had strolled away toward the fringe of the wood; and, after a pause, as of meditation, had disappeared into the darkness of the trees.

  He was recalled from his irrelevance by the voice of Juliet Bray, which rang out with an altogether new note of decision:

  “If that is the difficulty, it had best be cleared up. I am engaged to Mr. Crane, and when we told my brother he did not approve of it; that is all.”

  Neither Brain nor Fisher exhibited any surprise, but the former added, quietly:

  “Except, I suppose, that he and your brother went off into the wood to discuss it, where Mr. Crane mislaid his sword, not to mention his companion.”

  “And may I ask,” inquired Crane, with a certain flicker of mockery passing over his pallid features, “what I am supposed to have done with either of them? Let us adopt the cheerful thesis that I am a murderer; it has yet to be shown that I am a magician. If I ran your unfortunate friend through the body, what did I do with the body? Did I have it carried away by seven flying dragons, or was it merely a trifling matter of turning it into a milk-white hind?”

  “It is no occasion for sneering,” said the Anglo-Indian judge, with abrupt authority. “It doesn’t make it look better for you that you can joke about the loss.”

  Fisher’s dreamy, and even dreary, eye was still on the edge of the wood behind, and he became conscious of masses of dark red, like a stormy sunset cloud, glowing through the gray network of the thin trees, and the prince in his cardinal’s robes reemerged on to the pathway. Brain had had half a notion that the prince might have gone to look for the lost rapier. But when he reappeared he was carrying in his hand, not a sword, but an ax.

  The incongruity between the masquerade and the mystery had created a curious psychological atmosphere. At first they had all felt horribly ashamed at being caught in the foolish disguises of a festival, by an event that had only too much the character of a funeral. Many of them would have already gone back and dressed in clothes that were more funereal or at least more formal. But somehow at the moment this seemed like a second masquerade, more artificial and frivolous than the first. And as they reconciled themselves to their ridiculous trappings, a curious sensation had come over some of them, notably over the more sensitive, like Crane and Fisher and Juliet, but in some degree over everybody except the practical Mr. Brain. It was almost as if they were the ghosts of their own ancestors haunting that dark wood and dismal lake, and playing some old part that they only half remembered. The movements of those colored figures seemed to mean something that had been settled long before, like a silent heraldry. Acts, attitudes, external objects, were accepted as an allegory even without the key; and they knew when a crisis had come, when they did not know what it was. And somehow they knew subconsciously that the whole tale had taken a new and terrible turn, when they saw the prince stand in the gap of the gaunt trees, in his robes of angry crimson and with his lowering face of bronze, bearing in his hand a new shape of death. They could not have named a reason, but the two swords seemed indeed to have become toy swords and the whole tale of them broken and tossed away like a toy. Borodino looked like the Old World headsman, clad in terrible red, and carrying the ax for the execution of the criminal. And the criminal was not Crane.

  Mr. Brain of the Indian police was glaring at the new object, and it was a moment or two before he spoke, harshly and almost hoarsely.

  “What are you doing with that?” he asked. “Seems to be a woodman’s chopper.”

  “A natural association of ideas,” observed Horne Fisher. “If you meet a cat in a wood you think it’s a wildcat, though it may have just strolled from the drawing-room sofa. As a matter of fact, I happen to know that is not the woodman’s chopper. It’s the kitchen chopper, or meat ax, or something like that, that somebody has thrown away in the wood. I saw it in the kitchen myself when I was getting the potato sacks with which I reconstructed a mediaeval hermit.”

  “All the same, it is not without 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.”
