"Then, if he has been up there all the time, who can have done it?"
"Perhaps," said the other, "we might go upstairs and find out. We have half an hour before the police will move."
Leaving the body of the slain heiress in charge of the surgeons, Flambeau dashed up the stairs to the typewriting office, found it utterly empty, and then dashed up to his own. Having entered that, he abruptly returned with a new and white face to his friend.
"Her sister," he said, with an unpleasant seriousness, "her sister seems to have gone out for a walk."
Father Brown nodded. "Or, she may have gone up to the office of that sun man," he said. "If I were you I should just verify that, and then let us all talk it over in your office. No," he added suddenly, as if remembering something, "shall I ever get over that stupidity of mine? Of course, in their office downstairs."
Flambeau stared; but he followed the little father downstairs to the empty flat of the Staceys, where that impenetrable pastor took a large red-leather chair in the very entrance, from which he could see the stairs and landings, and waited. He did not wait very long. In about four minutes three figures descended the stairs, alike only in their solemnity. The first was Joan Stacey, the sister of the dead woman—evidently she had been upstairs in the temporary temple of Apollo; the second was the priest of Apollo himself, his litany finished, sweeping down the empty stairs in utter magnificence—something in his white robes, beard and parted hair had the look of Dore's Christ leaving the Pretorium; the third was Flambeau, black browed and somewhat bewildered.
Miss Joan Stacey, dark, with a drawn face and hair prematurely touched with grey, walked straight to her own desk and set out her papers with a practical flap. The mere action rallied everyone else to sanity. If Miss Joan Stacey was a criminal, she was a cool one. Father Brown regarded her for some time with an odd little smile, and then, without taking his eyes off her, addressed himself to somebody else.
"Prophet," he said, presumably addressing Kalon, "I wish you would tell me a lot about your religion."
"I shall be proud to do it," said Kalon, inclining his still crowned head, "but I am not sure that I understand."
"Why, it's like this," said Father Brown, in his frankly doubtful way: "We are taught that if a man has really bad first principles, that must be partly his fault. But, for all that, we can make some difference between a man who insults his quite clear conscience and a man with a conscience more or less clouded with sophistries. Now, do you really think that murder is wrong at all?"
"Is this an accusation?" asked Kalon very quietly.
"No," answered Brown, equally gently, "it is the speech for the defence."
In the long and startled stillness of the room the prophet of Apollo slowly rose; and really it was like the rising of the sun. He filled that room with his light and life in such a manner that a man felt he could as easily have filled Salisbury Plain. His robed form seemed to hang the whole room with classic draperies; his epic gesture seemed to extend it into grander perspectives, till the little black figure of the modern cleric seemed to be a fault and an intrusion, a round, black blot upon some splendour of Hellas.
"We meet at last, Caiaphas," said the prophet. "Your church and mine are the only realities on this earth. I adore the sun, and you the darkening of the sun; you are the priest of the dying and I of the living God. Your present work of suspicion and slander is worthy of your coat and creed. All your church is but a black police; you are only spies and detectives seeking to tear from men confessions of guilt, whether by treachery or torture. You would convict men of crime, I would convict them of innocence. You would convince them of sin, I would convince them of virtue.
"Reader of the books of evil, one more word before I blow away your baseless nightmares for ever. Not even faintly could you understand how little I care whether you can convict me or no. The things you call disgrace and horrible hanging are to me no more than an ogre in a child's toy-book to a man once grown up. You said you were offering the speech for the defence. I care so little for the cloudland of this life that I will offer you the speech for the prosecution. There is but one thing that can be said against me in this matter, and I will say it myself. The woman that is dead was my love and my bride; not after such manner as your tin chapels call lawful, but by a law purer and sterner than you will ever understand. She and I walked another world from yours, and trod palaces of crystal while you were plodding through tunnels and corridors of brick. Well, I know that policemen, theological and otherwise, always fancy that where there has been love there must soon be hatred; so there you have the first point made for the prosecution. But the second point is stronger; I do not grudge it you. Not only is it true that Pauline loved me, but it is also true that this very morning, before she died, she wrote at that table a will leaving me and my new church half a million. Come, where are the handcuffs? Do you suppose I care what foolish things you do with me? Penal servitude will only be like waiting for her at a wayside station. The gallows will only be going to her in a headlong car."
He spoke with the brain-shaking authority of an orator, and Flambeau and Joan Stacey stared at him in amazed admiration. Father 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
