They were sitting in a sort of partly unroofed outer court of the house, such as often forms the entrance to Spanish houses. It was dusk turning to dark; and as all that mountain air sharpens suddenly after sunset, a small stove stood on the flagstones, glowing with red eyes like a goblin, and painting a red pattern on the pavement; but scarcely a ray of it reached the lower bricks of the great bare, brown, brick wall that went soaring up above them into the deep blue night. Flambeau’s big broad-shouldered figure and great moustaches, like sabres, could be traced dimly in the twilight, as he moved about, drawing dark wine from a great cask and handing it round. In his shadow, the priest looked very shrunken and small, as if huddled over the stove; but the American visitor leaned forward elegantly with his elbow on his knee and his fine pointed features in the full light; his eyes shone with inquisitive intelligence.
“I can assure you, sir,” he was saying, “we consider your achievement in the matter of the Moonshine Murder the most remarkable triumph in the history of detective science.”
Father Brown murmured something; some might have imagined that the murmur was a little like a moan.
“We are well acquainted,” went on the stranger firmly, “with the alleged achievements of Dupin and others; with those of Lecocq, Sherlock Holmes, Nicholas Carter, and other imaginative incarnations of the craft. But we observe there is, in many ways, a marked difference between your own method of approach and that of these other thinkers, whether fictitious or actual. Some have spec’lated, sir, as to whether the difference of method may perhaps involve rather the absence of method.”
Father Brown was silent; then he started a little, almost as if he had been nodding over the stove, and said: “I beg your pardon. Yes. … Absence of method. … Absence of mind, too, I’m afraid.”
“I should say of strictly tabulated scientific method,” went on the inquirer. “Edgar Poe throws off several little essays in a conversational form, explaining Dupin’s method, with its fine links of logic. Dr. Watson had to listen to some pretty exact expositions of Holmes’s method, with its observation of material details. But nobody seems to have got on to any full account of your method, Father Brown, and I was informed you declined the offer to give a series of lectures in the States on the matter.”
“Yes,” said the priest, frowning at the stove. “I declined.”
“Your refusal gave rise to a remarkable lot of interesting talk,” remarked Chace. “I may say that some of our people are saying your science can’t be expounded, because it’s something more than just natural science. They say your secret’s not to be divulged, as being occult in its character.”
“Being what?” asked Father Brown, rather sharply.
“Why, kind of esoteric,” replied the other. “I can tell you, people got considerably worked up about Gallup’s murder, and Stein’s murder, and then old man Merton’s murder, and now Judge Gwynne’s murder, and a double murder by Dalmon, who was well known in the States. And there were you, on the spot every time, slap in the middle of it; telling everybody how it was done and never telling anybody how you knew. So some people got to think you knew without looking, so to speak. And Carlotta Brownson gave a lecture on Thought-Forms with illustrations from these cases of yours. The Second Sight Sisterhood of Indianapolis—”
Father Brown, was still staring at the stove; then he said quite loud, yet as if hardly aware that anyone heard him:
“Oh, I say. This will never do.”
“I don’t exactly know how it’s to be helped,” said Mr. Chace humorously. “The Second Sight Sisterhood want a lot of holding down. The only way I can think of stopping it is for you to tell us the secret after all.”
Father Brown groaned. He put his head on his hands and remained a moment, as if full of a silent convulsion of thought. Then he lifted his head and said in a dull voice:
“Very well. I must tell the secret.”
His eyes rolled darkly over the whole darkling scene, from the red eyes of the little stove to the stark expanse of the ancient wall, over which were standing out, more and more brightly, the strong stars of the south.
“The secret is,” he said; and then stopped as if unable to go on. Then he began again and said:
“You see, it was I who killed all those people.”
“What?” repeated the other, in a small voice out of a vast silence.
“You see, I had murdered
