"What on earth is the trouble?" demanded the other investigator.

"The trouble is," said Fisher, "that in a few days we should have had a very agreeable alternative--of hanging an innocent man or knocking the British Empire to h.e.l.l."

"Do you mean to say," asked Grayne, "that this infernal crime is not to be punished?"

Fisher looked at him steadily.

"It is already punished," he said.

After a moment's pause he went on. "You reconstructed the crime with admirable skill, old chap, and nearly all you said was true.

Two men with two coffee cups did go into the library and did put their cups on the bookstand and did go together to the well, and one of them was a murderer and had put poison in the other's cup. But it was not done while Boyle was looking at the revolving bookcase. He did look at it, though, searching for the Budge book with the note in it, but I fancy that Hastings had already moved it to the shelves on the wall. It was part of that grim game that he should find it first.

"Now, how does a man search a revolving bookcase? He does not generally hop all round it in a squatting att.i.tude, like a frog. He simply gives it a touch and makes it revolve."

He was frowning at the floor as he spoke, and there was a light under his heavy lids that was not often seen there. The mysticism that was buried deep under all the cynicism of his experience was awake and moving in the depths. His voice took unexpected turns and inflections, almost as if two men were speaking.

"That was what Boyle did; he barely touched the thing, and it went round as easily as the world goes round. Yes, very much as the world goes round, for the hand that turned it was not his. G.o.d, who turns the wheel of all the stars, touched that wheel and brought it full circle, that His dreadful justice might return."

"I am beginning," said Grayne, slowly, "to have some hazy and horrible idea of what you mean."

"It is very simple," said Fisher, "when Boyle straightened himself from his stooping posture, something had happened which he had not noticed, which his enemy had not noticed, which n.o.body had noticed.

The two coffee cups had exactly changed places."

The rocky face of Grayne seemed to have sustained a shock in silence; not a line of it altered, but his voice when it came was unexpectedly weakened.

"I see what you mean," he said, "and, as you say, the less said about it the better. It was not the lover who tried to get rid of the husband, but--the other thing. And a tale like that about a man like that would ruin us here. Had you any guess of this at the start?"

"The bottomless well, as I told you," answered Fisher, quietly; "that was what stumped me from the start. Not because it had anything to do with it, because it had nothing to do with it."

He paused a moment, as if choosing an approach, and then went on: "When a man knows his enemy will be dead in ten minutes, and takes him to the edge of an unfathomable pit, he means to throw his body into it. What else should he do? A born fool would have the sense to do it, and Boyle is not a born fool. Well, why did not Boyle do it?

The more I thought of it the more I suspected there was some mistake in the murder, so to speak. Somebody had taken somebody there to throw him in, and yet he was not thrown in. I had already an ugly, unformed idea of some subst.i.tution or reversal of parts; then I stooped to turn the bookstand myself, by accident, and I instantly knew everything, for I saw the two cups revolve once more, like moons in the sky."

After a pause, Cuthbert Grayne said, "And what are we to say to the newspapers?"

"My friend, Harold March, is coming along from Cairo to-day," said Fisher. "He is a very brilliant and successful journalist. But for all that he's a thoroughly honorable man, so you must not tell him the truth."

Half an hour later Fisher was again walking to and fro in front of the clubhouse, with Captain Boyle, the latter by this time with a very buffeted and bewildered air; perhaps a sadder and a wiser man.

"What about me, then?" he was saying. "Am I cleared? Am I not going to be cleared?"

"I believe and hope," answered Fisher, "that you are not going to be suspected. But you are certainly not going to be cleared. There must be no suspicion against him, and therefore no suspicion against you.

Any suspicion against him, let alone such a story against him, would knock us endways from Malta to Mandalay. He was a hero as well as a holy terror among the Moslems. Indeed, you might almost call him a Moslem hero in the English service. Of course he got on with them partly because of his own little dose of Eastern blood; he got it from his mother, the dancer from Damascus; everybody knows that."

"Oh," repeated Boyle, mechanically, staring at him with round eyes, "everybody knows that."

"I dare say there was a touch of it in his jealousy and ferocious vengeance," went on Fisher. "But, for all that, the crime would ruin us among the Arabs, all the more because it was something like a crime against hospitality. It's been hateful for you and it's pretty horrid for me. But there are some things that d.a.m.ned well can't be done, and while I'm alive that's one of them."

"What do you mean?" asked Boyle, glancing at him curiously. "Why should you, of all people, be so pa.s.sionate about it?"

Horne Fisher looked at the young man with a baffling expression.

"I suppose," he said, "it's because I'm a Little Englander."

"I can never make out what you mean by that sort of thing," answered Boyle, doubtfully.

"Do you think England is so little as all that?" said Fisher, with a warmth in his cold voice, "that it can't hold a man across a few thousand miles. You lectured me with a lot of ideal patriotism, my young friend; but it's practical patriotism now for you and me, and with no lies to help it. You talked as if everything always went right with us all over the world, in a triumphant crescendo culminating in Hastings. I tell you everything has gone wrong with us here, except Hastings. He was the one name we had left to conjure with, and that mustn't go as well, no, by G.o.d! It's bad enough that a gang of infernal Jews should plant us here, where there's no earthly English interest to serve, and all h.e.l.l beating up against us, simply because Nosey Zimmern has lent money to half the Cabinet.

It's bad enough that an old p.a.w.nbroker from Bagdad should make us fight his battles; we can't fight with our right hand cut off. Our one score was Hastings and his victory, which was really somebody else's victory. Tom Travers has to suffer, and so have you."

Then, after a moment's silence, he pointed toward the bottomless well and said, in a quieter tone:

"I told you that I didn't believe in the philosophy of the Tower of Aladdin. I don't believe in the Empire growing until it reaches the sky; I don't believe in the Union Jack going up and up eternally like the Tower. But if you think I am going to let the Union Jack go down and down eternally, like the bottomless well, down into the blackness of the bottomless pit, down in defeat and derision, amid the jeers of the very Jews who have sucked us dry--no I won't, and that's flat; not if the Chancellor were blackmailed by twenty millionaires with their gutter rags, not if the Prime Minister married twenty Yankee Jewesses, not if Woodville and Carstairs had shares in twenty swindling mines. If the thing is really tottering, G.o.d help it, it mustn't be we who tip it over."

Boyle was regarding him with a bewilderment that was almost fear, and had even a touch of distaste.

"Somehow," he said, "there seems to be something rather horrid about the things you know."

"There is," replied Horne Fisher. "I am not at all pleased with my small stock of knowledge and reflection. But as it is partly responsible for your not being hanged, I don't know that you need complain of it."

And, as if a little ashamed of his first boast, he turned and strolled away toward the bottomless well.

V. THE FAD OF THE FISHERMAN

A thing can sometimes be too extraordinary to be remembered. If it is clean out of the course of things, and has apparently no causes and no consequences, subsequent events do not recall it, and it remains only a subconscious thing, to be stirred by some accident long after. It drifts apart like a forgotten dream; and it was in the hour of many dreams, at daybreak and very soon after the end of dark, that such a strange sight was given to a man sculling a boat down a river in the West country. The man was awake; indeed, he considered himself rather wide awake, being the political journalist, Harold March, on his way to interview various political celebrities in their country seats. But the thing he saw was so inconsequent that it might have been imaginary. It simply slipped past his mind and was lost in later and utterly different events; nor did he even recover the memory till he had long afterward discovered the meaning.

Pale mists of morning lay on the fields and the rushes along one margin of the river; along the other side ran a wall of tawny brick almost overhanging the water. He had shipped his oars and was drifting for a moment with the stream, when he turned his head and saw that the monotony of the long brick wall was broken by a bridge; rather an elegant eighteenth-century sort of bridge with little columns of white stone turning gray. There had been floods and the river still stood very high, with dwarfish trees waist deep in it, and rather a narrow arc of white dawn gleamed under the curve of the bridge.

As his own boat went under the dark archway he saw another boat coming toward him, rowed by a man as solitary as himself. His posture prevented much being seen of him, but as he neared the bridge he stood up in the boat and turned round. He was already so close to the dark entry, however, that his whole figure was black against the morning light, and March could see nothing of his face except the end of two long whiskers or mustaches that gave something sinister to the silhouette, like horns in the wrong place. Even these details March would never have noticed but for what happened in the same instant. As the man came under the low bridge he made a leap at it and hung, with his legs dangling, letting the boat float away from under him. March had a momentary vision of two black kicking legs; then of one black kicking leg; and then of nothing except the eddying stream and the long perspective of the wall. But whenever he thought of it again, long afterward, when he understood the story in which it figured, it was always fixed in that one fantastic shape--as if those wild legs were a grotesque graven ornament of the bridge itself, in the manner of a gargoyle. At the moment he merely pa.s.sed, staring, down the stream. He could see no flying figure on the bridge, so it must have already fled; but he was half conscious of some faint significance in the fact that among the trees round the bridgehead opposite the wall he saw a lamp-post; and, beside the lamp-post, the broad blue back of an unconscious policeman.

Even before reaching the shrine of his political pilgrimage he had many other things to think of besides the odd incident of the bridge; for the management of a boat by a solitary man was not always easy even on such a solitary stream. And indeed it was only by an unforeseen accident that he was solitary. The boat had been purchased and the whole expedition planned in conjunction with a friend, who had at the last moment been forced to alter all his arrangements. Harold March was to have traveled with his friend Horne Fisher on that inland voyage to Willowood Place, where the Prime Minister was a guest at the moment. More and more people were hearing of Harold March, for his striking political articles were opening to him the doors of larger and larger salons; but he had never met the Prime Minister yet. Scarcely anybody among the general public had ever heard of Horne Fisher; but he had known the Prime Minister all his life. For these reasons, had the two taken the projected journey together, March might have been slightly disposed to hasten it and Fisher vaguely content to lengthen it out. For Fisher was one of those people who are born knowing the Prime Minister. The knowledge seemed to have no very exhilarant effect, and in his case bore some resemblance to being born tired. But he was distinctly annoyed to receive, just as he was doing a little light packing of fishing tackle and cigars for the journey, a telegram from Willowood asking him to come down at once by train, as the Prime Minister had to leave that night. Fisher knew that his friend the journalist could not possibly start till the next day, and he liked his friend the journalist, and had looked forward to a few days on the river. He did not particularly like or dislike the Prime Minister, but he intensely disliked the alternative of a few hours in the train. Nevertheless, he accepted Prime Ministers as he accepted railway trains--as part of a system which he, at least, was not the revolutionist sent on earth to destroy. So he telephoned to March, asking him, with many apologetic curses and faint d.a.m.ns, to take the boat down the river as arranged, that they might meet at Willowood by the time settled; then he went outside and hailed a taxicab to take him to the railway station. There he paused at the bookstall to add to his light luggage a number of cheap murder stories, which he read with great pleasure, and without any premonition that he was about to walk into as strange a story in real life.

A little before sunset he arrived, with his light suitcase in hand, before the gate of the long riverside gardens of Willowood Place, one of the smaller seats of Sir Isaac Hook, the master of much shipping and many newspapers. He entered by the gate giving on the road, at the opposite side to the river, but there was a mixed quality in all that watery landscape which perpetually reminded a traveler that the river was near. White gleams of water would shine suddenly like swords or spears in the green thickets. And even in the garden itself, divided into courts and curtained with hedges and high garden trees, there hung everywhere in the air the music of water. The first of the green courts which he entered appeared to be a somewhat neglected croquet lawn, in which was a solitary young man playing croquet against himself. Yet he was not an enthusiast for the game, or even for the garden; and his sallow but well-featured face looked rather sullen than otherwise. He was only one of those young men who cannot support the burden of consciousness unless they are doing something, and whose conceptions of doing something are limited to a game of some kind. He was dark and well dressed in a light holiday fashion, and Fisher recognized him at once as a young man named James Bullen, called, for some unknown reason, Bunker. He was the nephew of Sir Isaac; but, what was much more important at the moment, he was also the private secretary of the Prime Minister.

"Hullo, Bunker!" observed Horne Fisher. "You're the sort of man I wanted to see. Has your chief come down yet?"

"He's only staying for dinner," replied Bullen, with his eye on the yellow ball. "He's got a great speech to-morrow at Birmingham and he's going straight through to-night. He's motoring himself there; driving the car, I mean. It's the one thing he's really proud of."

"You mean you're staying here with your uncle, like a good boy?"

replied Fisher. "But what will the Chief do at Birmingham without the epigrams whispered to him by his brilliant secretary?"

"Don't you start ragging me," said the young man called Bunker.

"I'm only too glad not to go trailing after him. He doesn't know a thing about maps or money or hotels or anything, and I have to dance about like a courier. As for my uncle, as I'm supposed to come into the estate, it's only decent to be here sometimes."

"Very proper," replied the other. "Well, I shall see you later on,"

and, crossing the lawn, he pa.s.sed out through a gap in the hedge.

He was walking across the lawn toward the landing stage on the river, and still felt all around him, under the dome of golden evening, an Old World savor and reverberation in that riverhaunted garden. The next square of turf which he crossed seemed at first sight quite deserted, till he saw in the twilight of trees in one corner of it a hammock and in the hammock a man, reading a newspaper and swinging one leg over the edge of the net.
