cried Simeon; "you clergymen who tell us on Sunday in what a stillness the Lord smote Sennacherib. I believe that One who walks invisible in every house defended the honour of mine, and laid the defiler dead before the door of it. I believe the force in that blow was just the force there is in earthquakes, and no force less."
Wilfred said, with a voice utterly undescribable: "I told Norman myself to beware of the thunderbolt."
"That agent is outside my jurisdiction," said the inspector with a slight smile.
"You are not outside His," answered the smith; "see you to it," and, turning his broad back, he went into the house.
The shaken Wilfred was led away by Father Brown, who had an easy and friendly way with him. "Let us get out of this horrid place, Mr. Bohun," he said. "May I look inside your church? I hear it's one of the oldest in England. We take some interest, you know," he added with a comical grimace, "in old English churches."
Wilfred Bohun did not smile, for humour was never his strong point. But he nodded rather eagerly, being only too ready to explain the Gothic splendours to someone more likely to be sympathetic than the Presbyterian blacksmith or the atheist cobbler.
"By all means," he said; "let us go in at this side." And he led the way into the high side entrance at the top of the flight of steps. Father Brown was mounting the first step to follow him when he felt a hand on his shoulder, and turned to behold the dark, thin figure of the doctor, his face darker yet with suspicion.
"Sir," said the physician harshly, "you appear to know some secrets in this black business. May I ask if you are going to keep them to yourself?"
"Why, doctor," answered the priest, smiling quite pleasantly, "there is one very good reason why a man of my trade should keep things to himself when he is not sure of them, and that is that it is so constantly his duty to keep them to himself when he is sure of them. But if you think I have been discourteously reticent with you or anyone, I will go to the extreme limit of my custom. I will give you two very large hints."
"Well, sir?" said the doctor gloomily.
"First," said Father Brown quietly, "the thing is quite in your own province. It is a matter of physical science. The blacksmith is mistaken, not perhaps in saying that the blow was divine, but certainly in saying that it came by a miracle. It was no miracle, doctor, except in so far as man is himself a miracle, with his strange and wicked and yet half-heroic heart. The force that smashed that skull was a force well known to scientists—one of the most frequently debated of the laws of nature."
The doctor, who was looking at him with frowning intentness, only said: "And the other hint?"
"The other hint is this," said the priest. "Do you remember the blacksmith, though he believes in miracles, talking scornfully of the impossible fairy tale that his hammer had wings and flew half a mile across country?"
"Yes," said the doctor, "I remember that."
"Well," added Father Brown, with a broad smile, "that fairy tale was the nearest thing to the real truth that has been said to-day." And with that he turned his back and stumped up the steps after the curate.
The Reverend Wilfred, who had been waiting for him, pale and impatient, as if this little delay were the last straw for his nerves, led him immediately to his favourite corner of the church, that part of the gallery closest to the carved roof and lit by the wonderful window with the angel. The little Latin priest explored and admired everything exhaustively, talking cheerfully but in a low voice all the time. When in the course of his investigation he found the side exit and the winding stair down which Wilfred had rushed to find his brother dead, Father Brown ran not down but up, with the agility of a monkey, and his clear voice came from an outer platform above.
"Come up here, Mr. Bohun," he called. "The air will do you good."
Bohun 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
