some shadows it seemed to have turned totally grey.
"Be careful what you say," said Royce gruffly, "you'll frighten Miss Armstrong."
"I hope so," said the man with the clear voice.
As the woman winced and everyone else wondered, he went on: "I am somewhat used to Miss Armstrong's tremors. I have seen her trembling off and on for years. And some said she was shaking with cold and some she was shaking with fear, but I know she was shaking with hate and wicked anger—fiends that have had their feast this morning. She would have been away by now with her lover and all the money but for me. Ever since my poor old master prevented her from marrying that tipsy blackguard——"
"Stop," said Gilder very sternly. "We have nothing to do with your family fancies or suspicions. Unless you have some practical evidence, your mere opinions——"
"Oh! I'll give you practical evidence," cut in Magnus, in his hacking accent. "You'll have to subpoena me, Mr. Inspector, and I shall have to tell the truth. And the truth is this: An instant after the old man was pitched bleeding out of the window, I ran into the attic, and found his daughter swooning on the floor with a red dagger still in her hand. Allow me to hand that also to the proper authorities." He took from his tail-pocket a long horn-hilted knife with a red smear on it, and handed it politely to the sergeant. Then he stood back again, and his slits of eyes almost faded from his face in one fat Chinese sneer.
Merton felt an almost bodily sickness at the sight of him; and he muttered to Gilder: "Surely you would take Miss Armstrong's word against his?"
Father Brown suddenly lifted a face so absurdly fresh that it looked somehow as if he had just washed it. "Yes," he said, radiating innocence, "but is Miss Armstrong's word against his?"
The girl uttered a startled, singular little cry; everyone looked at her. Her figure was rigid as if paralysed; only her face within its frame of faint brown hair was alive with an appalling surprise. She stood like one of a sudden lassooed and throttled.
"This man," said Mr. Gilder gravely, "actually says that you were found grasping a knife, insensible, after the murder."
"He says the truth," answered Alice.
The next fact of which they were conscious was that Patrick Royce strode with his great stooping head into their ring and uttered the singular words: "Well, if I've got to go, I'll have a bit of pleasure first."
His huge shoulder heaved and he sent an iron fist smash into Magnus's bland Mongolian visage, laying him on the lawn as flat as a starfish. Two or three of the police instantly put their hands on Royce; but to the rest it seemed as if all reason had broken up and the universe were turning into a brainless harlequinade.
"None of that, Mr. Royce," Gilder had called out authoritatively. "I shall arrest you for assault."
"No, you won't," answered the secretary in a voice like an iron gong, "you will arrest me for murder."
Gilder threw an alarmed glance at the man knocked down; but since that outraged person was already sitting up and wiping a little blood off a substantially uninjured face, he only said shortly: "What do you mean?"
"It is quite true, as this fellow says," explained Royce, "that Miss Armstrong fainted with a knife in her hand. But she had not snatched the knife to attack her father, but to defend him."
"To defend him," repeated Gilder gravely. "Against whom?"
"Against me," answered the secretary.
Alice looked at him with a complex and baffling face; then she said in a low voice: "After it all, I am still glad you are brave."
"Come upstairs," said Patrick Royce heavily, "and I will show you the whole cursed thing."
The attic, which was the secretary's private place (and rather a small cell for so large a hermit), had indeed all the vestiges of a violent drama. Near the centre of the floor lay a large revolver as if flung away; nearer to the left was rolled a whisky bottle, open but not quite empty. The cloth of the little table lay dragged and trampled, and a length of cord, like that found on the corpse, was cast wildly across the windowsill. Two vases were smashed on the mantelpiece and one on the carpet.
"I was drunk," said Royce; and this simplicity in the prematurely battered man somehow had the pathos of the first sin of a baby.
"You all know about me," he continued huskily; "everybody knows how my story began, and it may as well end like that too. I was called a clever man once, and might have been a happy one; Armstrong saved the remains of a brain and body from the taverns, and was always kind to me in his own way, poor fellow! Only he wouldn't let me marry Alice here; and it will always be said that he was right enough. Well, you can form your own conclusions, and you won't want me to go into details. That is my whisky bottle half emptied in the corner; that is my revolver quite emptied on the carpet. It was the rope from my box that was found on the corpse, and it was from my window the corpse was thrown. You need not set detectives to grub up my tragedy; it is a common enough weed in this world. I give myself to the gallows; and, by God, that is enough!"
At a sufficiently delicate sign, the police gathered round the large man to lead him away; but their unobtrusiveness was somewhat staggered by the remarkable appearance of Father Brown, who was on his hands and knees on the carpet in the doorway, as if engaged in some kind of undignified prayers. Being a person utterly insensible to the social figure he cut, he remained in this posture, but turned a bright round face up at the company, presenting the appearance of a quadruped with a very comic human head.
"I say," he said good-naturedly, "this really won't do at all, you know. At the beginning you said we'd found no weapon. But now we're finding too many; there's the knife to stab, and the rope to strangle, and the pistol to shoot; and after all he broke his neck by falling out of a window! It won't do. It's not economical." And he shook his head at the ground as a horse does grazing.
Inspector Gilder had opened his mouth with serious intentions, but before he could speak the grotesque figure on the floor had gone on quite volubly.
"And now three quite impossible things. First, these holes in the carpet, where the six bullets have gone in. Why on earth should anybody fire at the carpet? A drunken man lets fly at his enemy's head, the thing that's grinning at him. He doesn't pick a quarrel with his feet, or lay siege to his slippers. And then there's the rope"—and having done with the carpet the speaker lifted his hands and put them in his pocket, but continued unaffectedly on his knees—"in what conceivable intoxication would anybody try to put a rope round a man's neck and finally put it round his leg? Royce, anyhow, was not so drunk as that, or he would be sleeping like a log by now. And, plainest of all, the whisky bottle. You suggest a dipsomaniac fought for the whisky bottle, and then having won, rolled it away in a corner, spilling one half and leaving the other. That is the very last thing a dipsomaniac would do."
He scrambled awkwardly to his feet, and said to the self-accused murderer in tones of limpid penitence: "I'm awfully sorry, my dear sir, but your tale is really rubbish."
"Sir," said Alice Armstrong in a low tone to the priest, "can I speak to you alone for a moment?"
This request forced the communicative cleric out of the gangway, and before he could speak in the next room, the girl was talking with strange incisiveness.
"You are a clever man," she said, "and you are trying to save Patrick, I know. But it's no use. The core of all this is black, and the more things you find out the more there will be against the miserable man I love."
"Why?"
