of the universe. "Let Cain pass by, for he belongs to God."
There was a long-drawn silence in the room when he had left it, which was to Flambeau's fierce wits one long agony of interrogation. Miss Joan Stacey very coolly tidied up the papers on her desk.
"Father," said Flambeau at last, "it is my duty, not my curiosity only—it is my duty to find out, if I can, who committed the crime."
"Which crime?" asked Father Brown.
"The one we are dealing with, of course," replied his impatient friend.
"We are dealing with two crimes," said Brown, "crimes of very different weight—and by very different criminals."
Miss Joan Stacey, having collected and put away her papers, proceeded to lock up her drawer. Father Brown went on, noticing her as little as she noticed him.
"The two crimes," he observed, "were committed against the same weakness of the same person, in a struggle for her money. The author of the larger crime found himself thwarted by the smaller crime; the author of the smaller crime got the money."
"Oh, don't go on like a lecturer," groaned Flambeau; "put it in a few words."
"I can put it in one word," answered his friend.
Miss Joan Stacey skewered her business-like black hat on to her head with a business-like black frown before a little mirror, and, as the conversation proceeded, took her handbag and umbrella in an unhurried style, and left the room.
"The truth is one word, and a short one," said Father Brown. "Pauline Stacey was blind."
"Blind!" repeated Flambeau, and rose slowly to his whole huge stature.
"She was subject to it by blood," Brown proceeded. "Her sister would have started eyeglasses if Pauline would have let her; but it was her special philosophy or fad that one must not encourage such diseases by yielding to them. She would not admit the cloud; or she tried to dispel it by will. So her eyes got worse and worse with straining; but the worst strain was to come. It came with this precious prophet, or whatever he calls himself, who taught her to stare at the hot sun with the naked eye. It was called accepting Apollo. Oh, if these new pagans would only be old pagans, they would be a little wiser! The old pagans knew that mere naked Nature-worship must have a cruel side. They knew that the eye of Apollo can blast and blind."
There was a pause, and the priest went on in a gentle and even broken voice. "Whether or no that devil deliberately made her blind, there is no doubt that he deliberately killed her through her blindness. The very simplicity of the crime is sickening. You know he and she went up and down in those lifts without official help; you know also how smoothly and silently the lifts slide. Kalon brought the lift to the girl's landing, and saw her, through the open door, writing in her slow, sightless way the will she had promised him. He called out to her cheerily that he had the lift ready for her, and she was to come out when she was ready. Then he pressed a button and shot soundlessly up to his own floor, walked through his own office, out on to his own balcony, and was safely praying before the crowded street when the poor girl, having finished her work, ran gaily out to where lover and lift were to receive her, and stepped—"
"Don't!" cried Flambeau.
"He ought to have got half a million by pressing that button," continued the little father, in the colourless voice in which he talked of such horrors. "But that went smash. It went smash because there happened to be another person who also wanted the money, and who also knew the secret about poor Pauline's sight. There was one thing about that will that I think nobody noticed: although it was unfinished and without signature, the other Miss Stacey and some servant of hers had already signed it as witnesses. Joan had signed first, saying Pauline could finish it later, with a typical feminine contempt for legal forms. Therefore, Joan wanted her sister to sign the will without real witnesses. Why? I thought of the blindness, and felt sure she had wanted Pauline to sign in solitude because she had wanted her not to sign at all.
"People like the Staceys always use fountain pens; but this was specially natural to Pauline. By habit and her strong will and memory she could still write almost as well as if she saw; but she could not tell when her pen needed dipping. Therefore, her fountain pens were carefully filled by her sister—all except this fountain pen. This was carefully not filled by her sister; the remains of the ink held out for a few lines and then failed altogether. And the prophet lost five hundred thousand pounds and committed one of the most brutal and brilliant murders in human history for nothing."
Flambeau went to the open door and heard the official police ascending the stairs. He turned and said: "You must have followed everything devilish close to have traced the crime to Kalon in ten minutes."
Father Brown gave a sort of start.
"Oh! to him," he said. "No; I had to follow rather close to find out about Miss Joan and the fountain pen. But I knew Kalon was the criminal before I came into the front door."
"You must be joking!" cried Flambeau.
"I'm quite serious," answered the priest. "I tell you I knew he had done it, even before I knew what he had done."
"But why?"
"These pagan stoics," said Brown reflectively, "always fail by their strength. There came a crash and a scream down the street, and the priest of Apollo did not start or look round. I did not know what it was. But I knew that he was expecting it."

The Sign of the Broken Sword
The thousand arms of the forest were grey, and its million fingers silver. In a sky of dark green-blue-like slate the stars were bleak and brilliant like splintered ice. All that thickly wooded and sparsely tenanted countryside was stiff with a bitter and brittle frost. The black hollows between the trunks of the trees looked like bottomless, black caverns of that Scandinavian hell, a hell of incalculable cold. Even the square stone tower of the church looked northern to the point of heathenry, as if it were some barbaric tower among the sea rocks of Iceland. It was a queer night for anyone to explore a churchyard. But, on the other hand, perhaps it was worth exploring.
It rose abruptly out of the ashen wastes of forest in a sort of hump or shoulder of green turf that looked grey in the starlight. Most of the graves were on a slant, and the path leading up to the church was as steep as a staircase. On the top of the hill, in the one flat and prominent place, was the monument for which the place was famous. It contrasted strangely with the featureless graves all round, for it was the work of one of the greatest sculptors of modern Europe; and yet his fame was at once forgotten in the fame of the man whose image he had made. It showed, by touches of the small silver pencil of starlight, the massive metal figure of a soldier recumbent, the strong hands sealed in an everlasting worship, the great head pillowed upon a gun. The venerable face was bearded, or rather whiskered, in the old, heavy Colonel Newcome fashion. The uniform, though suggested with the few strokes of simplicity, was that of modern war. By his right side lay a sword, of which the tip was broken off; on the left side lay a Bible. On glowing summer afternoons wagonettes came full of Americans and cultured suburbans to see the sepulchre; but even then they felt the vast forest land with its one dumpy dome of churchyard and church as a place oddly dumb and neglected. In this freezing darkness of mid-winter one would think he might be left alone with the stars. Nevertheless, in the stillness of those stiff woods a wooden gate creaked, and two dim figures dressed in black climbed up the little path to the tomb.
So faint was that frigid starlight that nothing could have been traced about them except that while they both wore black, one man was enormously big, and the other (perhaps by contrast) almost startlingly small. They went up to the great graven tomb of the historic warrior, and stood for a few minutes staring at it. There was no human, perhaps no living, thing for a wide circle; and a morbid fancy might well have wondered if they were human themselves. In any case, the beginning of their conversation might have seemed strange. After the first silence the small man said to the other:
"Where does a wise man hide a pebble?"
And
