the blank curiosity of his first innocence. It was rather that creative curiosity which comes when a man has the beginnings of an idea. "Say it again, please," he said in a simple, bothered manner; "do you mean that Todhunter can tie himself upall alone and untie himself all alone?" "That is what I mean," said the doctor.
"Jerusalem!" ejaculated Brown suddenly, "I wonder if it could possibly be that!"
He scuttled across the room rather like a rabbit, and peered with quite a new impulsiveness into the partially-covered face of the captive. Then he turned his own rather fatuous face to the company. "Yes, that's it!" he cried in a certain excitement. "Can't you see it in the man's face? Why, look at his eyes!"
Both the Professor and the girl followed the direction of his glance. And though the broad black scarf completely masked the lower half of Todhunter's visage, they did grow conscious of something struggling and intense about the upper part of it.
"His eyes do look queer," cried the young woman, strongly moved. "You brutes; I believe it's hurting him!"
"Not that, I think," said Dr Hood; "the eyes have certainly a singular expression. But I should interpret those transverse wrinkles as expressing rather such slight psychological abnormality--"
"Oh, bosh!" cried Father Brown: "can't you see he's laughing?"
"Laughing!" repeated the doctor, with a start; "but what on earth can he be laughing at?"
"Well," replied the Reverend Brown apologetically, "not to put too fine a point on it, I think he is laughing at you. And indeed, I'm a
little inclined to laugh at myself, now I know about it."
"Now you know about what?" asked Hood, in some exasperation. "Now I know," replied the priest, "the profession of Mr Todhunter."
He shuffled about the room, looking at one object after another with what seemed to be a vacant stare, and then invariably bursting into an equally vacant laugh, a highly irritating process for those who had to watch it. He laughed very much over the hat, still more uproariously over the broken glass, but the blood on the sword point sent him into mortal convulsions of amusement. Then he turned to the fuming specialist.
"Dr Hood," he cried enthusiastically, "you are a great poet! You have called an uncreated being out of the void. How much more godlike that is than if you had only ferreted out the mere facts! Indeed, the mere facts are rather commonplace and comic by comparison."
"I have no notion what you are talking about," said Dr Hood rather haughtily; "my facts are all inevitable, though necessarily incomplete. A place may be permitted to intuition, perhaps (or poetry if you prefer the term), but only because the corresponding details cannot as yet be ascertained. In the absence of Mr Glass--"
"That's it, that's it," said the little priest, nodding quite eagerly, "that's the first idea to get fixed; the absence of Mr Glass. He is so extremely absent. I suppose," he added reflectively, "that there was never anybody so absent as Mr Glass."

"Do you mean he is absent from the town?" demanded the doctor.
"I mean he is absent from everywhere," answered Father Brown; "he is absent from the Nature of Things, so to speak." "Do you seriously mean," said the specialist with a smile, "that there is no such person?"
The priest made a sign of assent. "It does seem a pity," he said.
Orion Hood broke into a contemptuous laugh. "Well," he said, "before we go on to the hundred and one other evidences, let us take
the first proof we found; the first fact we fell over when we fell into this room. If there is no Mr Glass, whose hat is this?"
"It is Mr Todhunter's," replied Father Brown.
"But it doesn't fit him," cried Hood impatiently. "He couldn't possibly wear it!"
Father Brown shook his head with ineffable mildness. "I never said he could wear it," he answered. "I said it was his hat. Or, if you insist on a shade of difference, a hat that is his."
"And what is the shade of difference?" asked the criminologist with a slight sneer.
"My good sir," cried the mild little man, with his first movement akin to impatience, "if you will walk down the street to the nearest
hatter's shop, you will see that there is, in common speech, a difference between a man's hat and the hats that are his."
"But a hatter," protested Hood, "can get money out of his stock of new hats. What could Todhunter get out of this one old hat?" "Rabbits," replied Father Brown promptly.
"What?" cried Dr Hood.
"Rabbits, ribbons, sweetmeats, goldfish, rolls of coloured paper," said the reverend gentleman with rapidity. "Didn't you see it all when you found out the faked ropes? It's just the same with the sword. Mr Todhunter hasn't got a scratch on him, as you say; but he's got a scratch in him, if you follow me."
"Do you mean inside Mr Todhunter's clothes?" inquired Mrs MacNab sternly.
"I do not mean inside Mr Todhunter's clothes," said Father Brown. "I mean inside Mr Todhunter." "Well, what in the name of Bedlam do you mean?"
"Mr Todhunter," explained Father Brown placidly, "is learning to be a professional conjurer, as well as juggler, ventriloquist, and expert in the rope trick. The conjuring explains the hat. It is without traces of hair, not because it is worn by the prematurely bald Mr Glass, but because it has never been worn by anybody. The juggling explains the three glasses, which Todhunter was teaching himself to throw up and catch in rotation. But, being only at the stage of practice, he smashed one glass against the ceiling. And the juggling also explains the sword, which it was Mr Todhunter's professional pride and duty to swallow. But, again, being at the stage of practice, he very slightly grazed the inside of his throat with the weapon. Hence he has a wound inside him, which I am sure (from the expression on his face) is not a serious one. He was also practising the trick of a release from ropes, like the Davenport Brothers, and he was just about to free himself when we all burst into the room. The cards, of course, are for card tricks, and they are scattered on the floor because he had just been practising one of those dodges of sending them flying through the air. He merely kept his trade secret, because he had to keep his tricks secret, like any other conjurer. But the mere fact of an idler in a top hat having once looked in at his back window, and been driven away by him with great indignation, was enough to set us all on a wrong track of romance,
and make us imagine his whole life overshadowed by the silk-hatted spectre of Mr Glass." "But What about the two voices?" asked Maggie, staring.
"Have you never heard a ventriloquist?" asked Father Brown. "Don't you know they speak first in their natural voice, and then an-swer themselves in just that shrill, squeaky, unnatural voice that you heard?"
There was a long silence, and Dr Hood regarded the little man who had spoken with a dark and attentive smile. "You are certainly a

very ingenious person," he said; "it could not have been done better in a book. But there is just one part of Mr Glass you have not succeeded in explaining away, and that is his name. Miss MacNab distinctly heard him so addressed by Mr Todhunter."
The Rev. Mr Brown broke into a rather childish giggle. "Well, that," he said, "that's the silliest part of the whole silly story. When our juggling friend here threw up the three glasses in turn, he counted
