A thought flashed across Flambeau’s face. “You mean to say,” he began, “that the will of Prince Saradine—”
“I am Prince Saradine,” said the old man, munching a salted almond.
Father Brown, who was looking at the birds outside, jumped as if he were shot, and put in at the window a pale face like a turnip.
“You are what?” he repeated in a shrill voice.
“Paul, Prince Saradine, A vos ordres,” said the venerable person politely, lifting a glass of sherry. “I live here very quietly, being a domestic kind of fellow; and for the sake of modesty I am called Mr. Paul, to distinguish me from my unfortunate brother Mr. Stephen. He died, I hear, recently—in the garden. Of course, it is not my fault if enemies pursue him to this place. It is owing to the regrettable irregularity of his life. He was not a domestic character.”
He relapsed into silence, and continued to gaze at the opposite wall just above the bowed and sombre head of the woman. They saw plainly the family likeness that had haunted them in the dead man. Then his old shoulders began to heave and shake a little, as if he were choking, but his face did not alter.
“My God!” cried Flambeau after a pause, “he’s laughing!”
“Come away,” said Father Brown, who was quite white. “Come away from this house of hell. Let us get into an honest boat again.”
Night had sunk on rushes and river by the time they had pushed off from the island, and they went down-stream in the dark, warming themselves with two big cigars that glowed like crimson ships’ lanterns. Father Brown took his cigar out of his mouth and said:
“I suppose you can guess the whole story now? After all, it’s a primitive story. A man had two enemies. He was a wise man. And so he discovered that two enemies are better than one.”
