"I'm afraid," said the American, in tones that were still doubtful, and keeping his eye on the priest rather as if he were a wild animal, "that you'd have to explain a lot to me before I knew what you were talking about. The science of detection——"
Father Brown snapped his fingers with the same animated annoyance. "That's it," he cried; "that's just where we part company. Science is a grand thing when you can get it; in its real sense one of the grandest words in the world. But what do these men mean, nine times out often, when they use it nowadays? When they say detection is a science? When they say criminology is a science? They mean getting outside a man and studying him as if he were a gigantic insect: in what they would call a dry impartial light, in what I should call a dead and dehumanized light. They mean getting a long way off him, as if he were a distant prehistoric monster; staring at the shape of his 'criminal skull' as if it were a sort of eerie growth, like the horn on a rhinoceros's nose. When the scientist talks about a type, he never means himself, but always his neighbour; probably his poorer neighbour. I don't deny the dry light may sometimes do good; though in one sense it's the very reverse of science. So far from being knowledge, it's actually suppression of what we know. It's treating a friend as a stranger, and pretending that something familiar is really remote and mysterious. It's like saying that a man has a proboscis between the eyes, or that he falls down in a fit of insensibility once every twenty-four hours. Well, what you call 'the secret' is exactly the opposite. I don't try to get outside the man. I try to get inside the murderer.... Indeed it's much more than that, don't you see? I am inside a man. I am always inside a man, moving his arms and legs; but I wait till I know I am inside a murderer, thinking his thoughts, wrestling with his passions; till I have bent myself into the posture of his hunched and peering hatred; till I see the world with his bloodshot and squinting eyes, looking between the blinkers of his half-witted concentration; looking up the short and sharp perspective of a straight road to a pool of blood. Till I am really a murderer."
"Oh," said Mr. Chace, regarding him with a long, grim face, and added: "And that is what you call a religious exercise."
"Yes," said Father Brown; "that is what I call a religious exercise."
After an instant's silence he resumed: "It's so real a religious exercise that I'd rather not have said anything about it. But I simply couldn't have you going off and telling all your countrymen that I had a secret magic connected with Thought-Forms, could I? I've put it badly, but it's true. No man's really any good till he knows how bad he is, or might be; till he's realized exactly how much right he has to all this snobbery, and sneering, and talking about 'criminals,' as if they were apes in a forest ten thousand miles away; till he's got rid of all the dirty self-deception of talking about low types and deficient skulls; till he's squeezed out of his soul the last drop of the oil of the Pharisees; till his only hope is somehow or other to have captured one criminal, and kept him safe and sane under his own hat."
Flambeau came forward and filled a great goblet with Spanish wine and set it before his friend, as he had already set one before his fellow guest. Then he himself spoke for the first time:
"I believe Father Brown has had a new batch of mysteries. We were talking about them the other day, I fancy. He has been dealing with some queer people since we last met."
"Yes; I know the stories more or less—but not the application," said Chace, lifting his glass thoughtfully. "Can you give me any examples, I wonder.... I mean, did you deal with this last batch in that introspective style?"
Father Brown also lifted his glass, and the glow of the fire turned the red wine transparent, like the glorious blood-red glass of a martyr's window. The red flame seemed to hold his eyes and absorb his gaze that sank deeper and deeper into it, as if that single cup held a red sea of the blood of all men, and his soul were a diver, ever plunging in dark humility and inverted imagination, lower than its lowest monsters and its most ancient slime. In that cup, as in a red mirror, he saw many things; the doings of his last days moved in crimson shadows; the examples that his companions demanded danced in symbolic shapes; and there passed before him all the stories that are told here. Now, the luminous wine was like a vast red sunset upon dark red sands, where stood dark figures of men; one was fallen and another running towards him. Then the sunset seemed to break up into patches: red lanterns swinging from garden trees and a pond gleaming red with reflection; and then all the colour seemed to cluster again into a great rose of red crystal, a jewel that irradiated the world like a red sun, save for the shadow of a tall figure with a high head-dress as of some prehistoric priest; and then faded again till nothing was left but a flame of wild red beard blowing in the wind upon a wild grey moor. All these things, which may be seen later from other angles and in other moods than his own, rose up in his memory at the challenge and began to form themselves into anecdotes and arguments.
"Yes," he said, as he raised the wine cup slowly to his lips, "I can remember pretty well——"
