“A black shape was seen in the passage. And you say you saw the black shape. Well, what shape was it?”
Father Brown blinked as under rebuke; but he had long known the literal nature of obedience. “The shape,” he said, “was short and thick, but had two sharp, black projections curved upwards on each side of the head or top, rather like horns, and—”
“Oh! the devil with horns, no doubt,” ejaculated Cowdray, sitting down in triumphant jocularity. “It was the devil come to eat Protestants.”
“No,” said the priest dispassionately; “I know who it was.”
Those in court had been wrought up to an irrational, but real sense of some monstrosity. They had forgotten the figure in the dock and thought only of the figure in the passage. And the figure in the passage, described by three capable and respectable men who had all seen it, was a shifting nightmare: one called it a woman, and the other a beast, and the other a devil....
The judge was looking at Father Brown with level and piercing eyes. “You are a most extraordinary witness,” he said; “but there is something about you that makes me think you are trying to tell the truth. Well, who was the man you saw in the passage?”
“He was myself,” said Father Brown.
Butler, K.C., sprang to his feet in an extraordinary stillness, and said quite calmly: “Your lordship will allow me to cross-examine?” And then, without stopping, he shot at Brown the apparently disconnected question: “You have heard about this dagger; you know the experts say the crime was committed with a short blade?”
“A short blade,” assented Brown, nodding solemnly like an owl, “but a very long hilt.”
Before the audience could quite dismiss the idea that the priest had really seen himself doing murder with a short dagger with a long hilt (which seemed somehow to make it more horrible), he had himself hurried on to explain.
