which he evidently belonged. Moreover, under all the stains of his plunging through ploughed fields or bursting through dusty hedges, the man was comparatively clean. This might mean, of course, that he had only just broken prison; but it reminded me more of the desperate decency of the comparatively respectable poor. His demeanour was, I am bound to confess, quite in accordance with theirs. He was silent and dignified as they are; he seemed to have a big, but buried, grievance, as they do. He professed total ignorance of the crime and the whole question; and showed nothing but a sullen impatience for something sensible that might come to take him out of his meaningless scrape. He asked me more than once if he could telephone for a lawyer who had helped him a long time ago in a trade dispute, and in every sense acted as you would expect an innocent man to act. There was nothing against him in the world except that little finger on the dial that pointed to the change of his pulse.
'Then, sir, the machine was on its trial; and the machine was right. By the time I came with him out of the private room into the vestibule where all sorts of other people were awaiting examination, I think he had already more or less made up his mind to clear things up by something like a confession. He turned to me and began to say in a low voice: 'Oh, I can't stick this any more. If you must know all about me—'
'At the same instant one of the poor women sitting on the long bench stood up, screaming aloud and pointing at him with her finger. I have never in my life heard anything more demoniacally distinct. Her lean finger seemed to pick him out as if it were a pea-shooter. Though the word was a mere howl, every syllable was as clear as a separate stroke on the clock.
''Drugger Davis !' she shouted. 'They've got Drugger Davis!'
'Among the wretched women, mostly thieves and streetwalkers, twenty faces were turned, gaping with glee and hate. If I had never heard the words, I should have known by the very shock upon his features that the so- called Oscar Rian had heard his real name. But I'm not quite so ignorant, you may be surprised to hear. Drugger Davis was one of the most terrible and depraved criminals that ever baffled our police. It is certain he had done murder more than once long before his last exploit with the warder. But he was never entirely fixed for it, curiously enough because he did it in the same manner as those milder—or meaner—crimes for which he was fixed pretty often. He was a handsome, well-bred-looking brute, as he still is, to some extent; and he used mostly to go about with barmaids or shop-girls and do them out of their money. Very often, though, he went a good deal farther; and they were found drugged with cigarettes or chocolates and their whole property missing. Then came one case where the girl was found dead; but deliberation could not quite be proved, and, what was more practical still, the criminal could not be found. I heard a rumour of his having reappeared somewhere in the opposite character this time, lending money instead of borrowing it; but still to such poor widows as he might personally fascinate, but still with the same bad result for them. Well, there is your innocent man, and there is his innocent record. Even, since then, four criminals and three warders have identified him and confirmed the story. Now what have you got to say to my poor little machine after that? Hasn't the machine done for him? Or do you prefer to say that the woman and I have done for him?'
'As to what you've done for him,' replied Father Brown, rising and shaking himself in a floppy way, 'you've saved him from the electrical chair. I don't think they can kill Drugger Davis on that old vague story of the poison; and as for the convict who killed the warder, I suppose it's obvious that you haven't got him. Mr Davis is innocent of that crime, at any rate.'
'What do you mean?' demanded the other. 'Why should he be innocent of that crime?'
'Why, bless us all!' cried the small man in one of his rare moments of animation, 'why, because he's guilty of the other crimes! I don't know what you people are made of. You seem to think that all sins are kept together in a bag. You talk as if a miser on Monday were always a spendthrift on Tuesday. You tell me this man you have here spent weeks and months wheedling needy women out of small sums of money; that he used a drug at the best, and a poison at the worst; that he turned up afterwards as the lowest kind of moneylender, and cheated most poor people in the same patient and pacific style. Let it be granted—let us admit, for the sake of argument, that he did all this. If that is so, I will tell you what he didn't do. He didn't storm a spiked wall against a man with a loaded gun. He didn't write on the wall with his own hand, to say he had done it. He didn't stop to state that his justification was self-defence. He didn't explain that he had no quarrel with the poor warder. He didn't name the house of the rich man to which he was going with the gun. He didn't write his own, initials in a man's blood. Saints alive! Can't you see the whole character is different, in good and evil? Why, you don't seem to be like I am a bit. One would think you'd never had any vices of your own.'
The amazed American had already parted his lips in protest when the door of his private and official room was hammered and rattled in an unceremonious way to which he was totally unaccustomed.
The door flew open. The moment before Greywood Usher had been coming to the conclusion that Father Brown might possibly be mad. The moment after he began to think he was mad himself. There burst and fell into his private room a man in the filthiest rags, with a greasy squash hat still askew on his head, and a shabby green shade shoved up from one of his eyes, both of which were glaring like a tiger's. The rest of his face was almost undiscoverable, being masked with a matted beard and whiskers through which the nose could barely thrust itself, and further buried in a squalid red scarf or handkerchief. Mr Usher prided himself on having seen most of the roughest specimens in the State, but he thought he had never seen such a baboon dressed as a scarecrow as this. But, above all, he had never in all his placid scientific existence heard a man like that speak to him first.
'See here, old man Usher,' shouted the being in the red handkerchief, 'I'm getting tired. Don't you try any of your hide-and-seek on me; I don't get fooled any. Leave go of my guests, and I'll let up on the fancy clockwork. Keep him here for a split instant and you'll feel pretty mean. I reckon I'm not a man with no pull.'
The eminent Usher was regarding the bellowing monster with an amazement which had dried up all other sentiments. The mere shock to his eyes had rendered his ears, almost useless. At last he rang a bell with a hand of violence. While the bell was still strong and pealing, the voice of Father Brown fell soft but distinct.
'I have a suggestion to make,' he said, 'but it seems a little confusing. I don't know this gentleman—but—but I think I know him. Now, you know him—you know him quite well—but you don't know him—naturally. Sounds paradoxical, I know.'
'I reckon the Cosmos is cracked,' said Usher, and fell asprawl in his round office chair.
'Now, see here,' vociferated the stranger, striking the table, but speaking in a voice that was all the more mysterious because it was comparatively mild and rational though still resounding. 'I won't let you in. I want —'
'Who in hell are you?' yelled Usher, suddenly sitting up straight.
'I think the gentleman's name is Todd,' said the priest.
Then he picked up the pink slip of newspaper.
'I fear you don't read the Society papers properly,' he said, and began to read out in a monotonous voice, ''Or locked in the jewelled bosoms of our city's gayest leaders; but there is talk of a pretty parody of the manners and customs of the other end of Society's scale.' There's been a big Slum Dinner up at Pilgrim's Pond tonight; and a man, one of the guests, disappeared. Mr Ireton Todd is a good host, and has tracked him here, without even waiting to take off his fancy-dress.'
'What man do you mean?'
'I mean the man with comically ill-fitting clothes you saw running across the ploughed field. Hadn't you better go and investigate him? He will be rather impatient to get back to his champagne, from which he ran away in such a hurry, when the convict with the gun hove in sight.'
'Do you seriously mean—' began the official.
'Why, look here, Mr Usher,' said Father Brown quietly, 'you said the machine couldn't make a mistake; and in one sense it didn't. But the other machine did; the machine that worked it. You assumed that the man in rags jumped at the name of Lord Falconroy, because he was Lord Falconroy's murderer. He jumped at the name of Lord Falconroy because he is Lord Falconroy.'
'Then why the blazes didn't he say so?' demanded the staring Usher.
'He felt his plight and recent panic were hardly patrician,' replied the priest, 'so he tried to keep the name back at first. But he was just going to tell it you, when'—and Father Brown looked down at his boots—'when a woman found another name for him.'
'But you can't be so mad as to say,' said Greywood Usher, very white, 'that Lord Falconroy was Drugger Davis.'
The priest looked at him very earnestly, but with a baffling and undecipherable face.
'I am not saying anything about it,' he said. 'I leave all the rest to you. Your pink paper says that the title
