followed him, and came out on a kind of stone gallery or balcony outside the building, from which one could see the illimitable plain in which their small hill stood, wooded away to the purple horizon and dotted with villages and farms. Clear and square, but quite small beneath them, was the blacksmith's yard, where the inspector still stood taking notes and the corpse still lay like a smashed fly.
"Might be the map of the world, mightn't it?" said Father Brown.
"Yes," said Bohun very gravely, and nodded his head.
Immediately beneath and about them the lines of the Gothic building plunged outwards into the void with a sickening swiftness akin to suicide. There is that element of Titan energy in the architecture of the Middle Ages that, from whatever aspect it be seen, it always seems to be rushing away, like the strong back of some maddened horse. This church was hewn out of ancient and silent stone, bearded with old fungoids and stained with the nests of birds. And yet, when they saw it from below, it sprang like a fountain at the stars; and when they saw it, as now, from above, it poured like a cataract into a voiceless pit. For these two men on the tower were left alone with the most terrible aspect of Gothic; the monstrous foreshortening and disproportion, the dizzy perspectives, the glimpses of great things small and small things great; a topsy-turvydom of stone in the mid-air. Details of stone, enormous by their proximity, were relieved against a pattern of fields and farms, pygmy in their distance. A carved bird or beast at a corner seemed like some vast walking or flying dragon wasting the pastures and villages below. The whole atmosphere was dizzy and dangerous, as if men were upheld in air amid the gyrating wings of colossal genii; and the whole of that old church, as tall and rich as a cathedral, seemed to sit upon the sunlit country like a cloudburst.
"I think there is something rather dangerous about standing on these high places even to pray," said Father Brown. "Heights were made to be looked at, not to be looked from."
"Do you mean that one may fall over," asked Wilfred.
"I mean that one's soul may fall if one's body doesn't," said the other priest.
"I scarcely understand you," remarked Bohun indistinctly.
"Look at that blacksmith, for instance," went on Father Brown calmly; "a good man, but not a Christian—hard, imperious, unforgiving. Well, his Scotch religion was made up by men who prayed on hills and high crags, and learnt to look down on the world more than to look up at heaven. Humility is the mother of giants. One sees great things from the valley; only small things from the peak."
"But he—he didn't do it," said Bohun tremulously.
"No," said the other in an odd voice; "we know he didn't do it."
After a moment he resumed, looking tranquilly out over the plain with his pale grey eyes. "I knew a man," he said, "who began by worshipping with others before the altar, but who grew fond of high and lonely places to pray from, corners or niches in the belfry or the spire. And once in one of those dizzy places, where the whole world seemed to turn under him like a wheel, his brain turned also, and he fancied he was God. So that, though he was a good man, he committed a great crime."
Wilfred's face was turned away, but his bony hands turned blue and white as they tightened on the parapet of stone.
"He thought it was given to him to judge the world and strike down the sinner. He would never have had such a thought if he had been kneeling with other men upon a floor. But he saw all men walking about like insects. He saw one especially strutting just below him, insolent and evident by a bright green hat—a poisonous insect."
Rooks cawed round the corners of the belfry; but there was no other sound till Father Brown went on.
"This also tempted him, that he had in his hand one of the most awful engines of nature; I mean gravitation, that mad and quickening rush by which all earth's creatures fly back to her heart when released. See, the inspector is strutting just below us in the smithy. If I were to toss a pebble over this parapet it would be something like a bullet by the time it struck him. If I were to drop a hammer—even a small hammer——"
Wilfred Bohun threw one leg over the parapet, and Father Brown had him in a minute by the collar.
"Not by that door," he said quite gently; "that door leads to hell."
Bohun staggered back against the wall, and stared at him with frightful eyes.
"How do you know all this?" he cried. "Are you a devil?"
"I am a man," answered Father Brown gravely; "and therefore have all devils in my heart. Listen to me," he said after a short pause. "I know what you did—at least, I can guess the great part of it. When you left your brother you were racked with no unrighteous rage, to the extent even that you snatched up a small hammer, half inclined to kill him with his foulness on his mouth. Recoiling, you thrust it under your buttoned coat instead, and rushed into the church. You pray wildly in many places, under the angel window, upon the platform above, and a higher platform still, from which you could see the colonel's Eastern hat like the back of a green beetle crawling about. Then something snapped in your soul, and you let God's thunderbolt fall."
Wilfred put a weak hand to his head, and asked in a low voice: "How did you know that his hat looked like a green beetle?"
"Oh, that," said the other with the shadow of a smile, "that was common sense. But hear me further. I say I know all this; but no one else shall know it. The next step is for you; I shall take no more steps; I will seal this with the seal of confession. If you ask me why, there are many reasons, and only one that concerns you. I leave things to you because you have not yet gone very far wrong, as assassins go. You did not help to fix the crime on the smith when it was easy; or on his wife, when that was easy. You tried to fix it on the imbecile because you knew that he could not suffer. That was one of the gleams that it is my business to find in assassins. And now come down into the village, and go your own way as free as the wind; for I have said my last word."
They went down the winding stairs in utter silence, and came out into the sunlight by the smithy. Wilfred Bohun carefully unlatched the wooden gate of the yard, and going up to the inspector, said: "I wish to give myself up; I have killed my brother."
The Eye of Apollo
That singular smoky sparkle, at once a confusion and a transparency, which is the strange secret of the Thames, was changing more and more from its grey to its glittering extreme as the sun climbed to the zenith over Westminster, and two men crossed Westminster Bridge. One man was very tall and the other very short; they might even have been fantastically compared to the arrogant clock-tower of Parliament and the humbler humped shoulders of the Abbey, for the short man was in clerical dress. The official description of the tall man was M. Hercule Flambeau, private detective, and he was going to his new offices in a new pile of flats facing the Abbey entrance. The official description of the short man was the Reverend J. Brown, attached to St. Francis Xavier's Church, Camberwell, and he was coming from a Camberwell deathbed to see the new offices of his friend.
The building was American in its sky-scraping altitude, and American also in the oiled elaboration of its machinery of telephones and lifts. But it was barely finished and still understaffed; only three tenants had moved in; the office just above Flambeau was occupied, as also was the office just below him; the two floors above that and the three floors below were entirely bare. But the first glance at the new tower of flats caught something much more arresting. Save for a few relics of scaffolding, the one glaring object was erected outside the office just above Flambeau's. It was an enormous gilt effigy of the human eye, surrounded with rays of gold, and taking up as much room as two or three of the office windows.
"What on earth is that?" asked Father Brown, and stood still.
"Oh, a new religion," said Flambeau, laughing; "one of those new religions that forgive your sins by saying you never had any. Rather like Christian Science, I should think. The fact is that a fellow calling himself Kalon (I don't know what his name is, except that
