Brown's face seemed to express nothing but extreme distress; he looked at the ground with one wrinkle of pain across his forehead. The prophet of the sun leaned easily against the mantelpiece and resumed:
"In a few words I have put before you the whole case against me—the only possible case against me. In fewer words still I will blow it to pieces, so that not a trace of it remains. As to whether I have committed this crime, the truth is in one sentence: I could not have committed this crime. Pauline Stacey fell from this floor to the ground at five minutes past twelve. A hundred people will go into the witness-box and say that I was standing out upon the balcony of my own rooms above from just before the stroke of noon to a quarter-past—the usual period of my public prayers. My clerk (a respectable youth from Clapham, with no sort of connection with me) will swear that he sat in my outer office all the morning, and that no communication passed through. He will swear that I arrived a full ten minutes before the hour, fifteen minutes before any whisper of the accident, and that I did not leave the office or the balcony all that time. No one ever had so complete an alibi; I could subpoena half Westminster. I think you had better put the handcuffs away again. The case is at an end.
"But last of all, that no breath of this idiotic suspicion remain in the air, I will tell you all you want to know. I believe I do know how my unhappy friend came by her death. You can, if you choose, blame me for it, or my faith and philosophy at least; but you certainly cannot lock me up. It is well known to all students of the higher truths that certain adepts and illuminati have in history attained the power of levitation—that is, of being self-sustained upon the empty air. It is but a part of that general conquest of matter which is the main element in our occult wisdom. Poor Pauline was of an impulsive and ambitious temper. I think, to tell the truth, she thought herself somewhat deeper in the mysteries than she was; and she has often said to me, as we went down in the lift together, that if one's will were strong enough, one could float down as harmlessly as a feather. I solemnly believe that in some ecstasy of noble thoughts she attempted the miracle. Her will, or faith, must have failed her at the crucial instant, and the lower law of matter had its horrible revenge. There is the whole story, gentlemen, very sad and, as you think, very presumptuous and wicked, but certainly not criminal or in any way connected with me. In the short-hand of the police-courts, you had better call it suicide. I shall always call it heroic failure for the advance of science and the slow scaling of heaven."
It was the first time Flambeau had ever seen Father Brown vanquished. He still sat looking at the ground, with a painful and corrugated brow, as if in shame. It was impossible to avoid the feeling which the prophet's winged words had fanned, that here was a sullen, professional suspecter of men overwhelmed by a prouder and purer spirit of natural liberty and health. At last he said, blinking as if in bodily distress: "Well, if that is so, sir, you need do no more than take the testamentary paper you spoke of and go. I wonder where the poor lady left it."
"It will be over there on her desk by the door, I think," said Kalon, with that massive innocence of manner that seemed to acquit him wholly. "She told me specially she would write it this morning, and I actually saw her writing as I went up in the lift to my own room."
"Was her door open then?" asked the priest, with his eye on the corner of the matting.
"Yes," said Kalon calmly.
"Ah! it has been open ever since," said the other, and resumed his silent study of the mat.
"There is a paper over here," said the grim Miss Joan, in a somewhat singular voice. She had passed over to her sister's desk by the doorway, and was holding a sheet of blue foolscap in her hand. There was a sour smile on her face that seemed unfit for such a scene or occasion, and Flambeau looked at her with a darkening brow.
Kalon the prophet stood away from the paper with that loyal unconsciousness that had carried him through. But Flambeau took it out of the lady's hand, and read it with the utmost amazement. It did, indeed, begin in the formal manner of a will, but after the words "I give and bequeath all of which I die possessed" the writing abruptly stopped with a set of scratches, and there was no trace of the name of any legatee. Flambeau, in wonder, handed this truncated testament to his clerical friend, who glanced at it and silently gave it to the priest of the sun.
An instant afterwards that pontiff, in his splendid sweeping draperies, had crossed the room in two great strides, and was towering over Joan Stacey, his blue eyes standing from his head.
"What monkey tricks have you been playing here?" he cried. "That's not all Pauline wrote."
They were startled to hear him speak in quite a new voice, with a Yankee shrillness in it; all his grandeur and good English had fallen from him like a cloak.
"That is the only thing on her desk," said Joan, and confronted him steadily with the same smile of evil favour.
Of a sudden the man broke out into blasphemies and cataracts of incredulous words. There was something shocking about the dropping of his mask; it was like a man's real face falling off.
"See here!" he cried in broad American, when he was breathless with cursing, "I may be an adventurer, but I guess you're a murderess. Yes, gentlemen, here's your death explained, and without any levitation. The poor girl is writing a will in my favour; her cursed sister comes in, struggles for the pen, drags her to the well, and throws her down before she can finish it. Sakes! I reckon we want the handcuffs after all."
"As you have truly remarked," replied Joan, with ugly calm, "your clerk is a very respectable young man, who knows the nature of an oath; and he will swear in any court that I was up in your office arranging some typewriting work for five minutes before and five minutes after my sister fell. Mr. Flambeau will tell you that he found me there."
There was a silence.
"Why, then," cried Flambeau, "Pauline was alone when she fell, and it was suicide!"
"She was alone when she fell," said Father Brown, "but it was not suicide."
"Then how did she die?" asked Flambeau impatiently.
"She was murdered."
"But she was alone," objected the detective.
"She was murdered when she was all alone," answered the priest.
All the rest stared at him, but he remained sitting in the same old dejected attitude, with a wrinkle in his round forehead and an appearance of impersonal shame and sorrow; his voice was colourless and sad.
"What I want to know," cried Kalon, with an oath, "is when the police are coming for this bloody and wicked sister. She's killed her flesh and blood; she's robbed me of half a million that was just as sacredly mine as—"
"Come, come, prophet," interrupted Flambeau, with a kind of sneer; "remember that all this world is a cloudland."
The hierophant of the sun-god made an effort to climb back on his pedestal. "It is not the mere money," he cried, "though that would equip the cause throughout the world. It is also my beloved one's wishes. To Pauline all this was holy. In Pauline's eyes—"
Father Brown suddenly sprang erect, so that his chair fell over flat behind him. He was deathly pale, yet he seemed fired with a hope; his eyes shone.
"That's it!" he cried in a clear voice. "That's the way to begin. In Pauline's eyes—"
The tall prophet retreated before the tiny priest in an almost mad disorder. "What do you mean? How dare you?" he cried repeatedly.
"In Pauline's eyes," repeated the priest, his own shining more and more. "Go on—in God's name, go on. The foulest crime the fiends ever prompted feels lighter after confession; and I implore you to confess. Go on, go on—in Pauline's eyes—"
"Let me go, you devil!" thundered Kalon, struggling like a giant in bonds. "Who are you, you cursed spy, to weave your spiders' webs round me, and peep and peer? Let me go."
"Shall I stop him?" asked Flambeau, bounding towards the exit, for Kalon had already thrown the door wide open.
"No; let him pass," said Father Brown, with a strange deep sigh that seemed to come from
