"The fourth and fifth points are pretty conclusive," said the priest calmly, "especially if you take them together. The first is that Maurice Mair seems to have had no funeral in particular, considering he was a cadet of a great family. He must have been buried hurriedly; perhaps secretly. And the last point is, that James Mair instantly disappeared to foreign parts; fled, in fact, to the ends of the earth.

"And so," he went on, still in the same soft voice, "when you would blacken my religion to brighten the story of the pure and perfect affection of two brothers, it seems——"

"Stop!" cried Outram in a tone like a pistol shot. "I must tell you more, or you will fancy worse. Let me tell you one thing to start with. It was a fair fight."

"Ah," said Father Brown, and seemed to exhale a huge breath.

"It was a duel," said the other. "It was probably the last duel fought in England, and it is long ago now."

"That's better," said Father Brown. "Thank God; that's a great deal better."

"Better than the ugly things you thought of, I suppose?" said the general gruffly. "Well, it's all very well for you to sneer at the pure and perfect affection; but it was true for all that. James Mair really was devoted to his cousin, who'd grown up with him like a younger brother. Elder brothers and sisters do sometimes devote themselves to a child like that, especially when he's a sort of infant phenomenon. But James Mair was the sort of simple character in whom even hate is in a sense unselfish. I mean that even when his tenderness turns to rage it is still objective, directed outwards to its object; he isn't conscious of himself. Now poor Maurice Mair was just the opposite. He was far more friendly and popular; but his success had made him live in a house of mirrors. He was first in every sort of sport and art and accomplishment; he nearly always won and took his winning amiably. But if ever, by any chance, he lost, there was just a glimpse of something not so amiable; he was a little jealous. I needn't tell you the whole miserable story of how he was a little jealous of his cousin's engagement; how he couldn't keep his restless vanity from interfering. It's enough to say that one of the few things in which James Mair was admittedly ahead of him was marksmanship with a pistol; and with that the tragedy ended."

"You mean the tragedy began," replied the priest. "The tragedy of the survivor. I thought he did not need any monkish vampires to make him miserable."

"To my mind he's more miserable than he need be," said the general. "After all, as I say, it was a ghastly tragedy, but it was a fair fight. And Jim had great provocation."

"How do you know all this?" asked the priest.
