The prince put the white hat and yellow gloves on the table and offered his hand quite cordially.
"Delighted to see you here, Mr. Flambeau," he said. "Knowing you very well by reputation, if that's not an indiscreet remark."
"Not at all," answered Flambeau, laughing. "I am not sensitive. Very few reputations are gained by unsullied virtue."
The prince flashed a sharp look at him to see if the retort had any personal point; then he laughed also and offered chairs to everyone, including himself.
"Pleasant little place, this, I think," he said with a detached air. "Not much to do, I fear; but the fishing is really good."
The priest, who was staring at him with the grave stare of a baby, was haunted by some fancy that escaped definition. He looked at the grey, carefully curled hair, yellow white visage, and slim, somewhat foppish figure. These were not unnatural, though perhaps a shade prononcé, like the outfit of a figure behind the footlights. The nameless interest lay in something else, in the very framework of the face; Brown was tormented with a half memory of having seen it somewhere before. The man looked like some old friend of his dressed up. Then he suddenly remembered the mirrors, and put his fancy down to some psychological effect of that multiplication of human masks.
Prince Saradine distributed his social attentions between his guests with great gaiety and tact. Finding the detective of a sporting turn and eager to employ his holiday, he guided Flambeau and Flambeau's boat down to the best fishing spot in the stream, and was back in his own canoe in twenty minutes to join Father Brown in the library and plunge equally politely into the priest's more philosophic pleasures. He seemed to know a great deal both about the fishing and the books, though of these not the most edifying; he spoke five or six languages, though chiefly the slang of each. He had evidently lived in varied cities and very motley societies, for some of his cheerfullest stories were about gambling hells and opium dens, Australian bushrangers or Italian brigands. Father Brown knew that the once-celebrated Saradine had spent his last few years in almost ceaseless travel, but he had not guessed that the travels were so disreputable or so amusing.
Indeed, with all his dignity of a man of the world, Prince Saradine radiated to such sensitive observers as the priest, a certain atmosphere of the restless and even the unreliable. His face was fastidious, but his eye was wild; he had little nervous tricks, like a man shaken by drink or drugs, and he neither had, nor professed to have, his hand on the helm of household affairs. All these were left to the two old servants, especially to the butler, who was plainly the central pillar of the house. Mr. Paul, indeed, was not so much a butler as a sort of steward or, even, chamberlain; he dined privately, but with almost as much pomp as his master; he was feared by all the servants; and he consulted with the prince decorously, but somewhat unbendingly—rather as if he were the prince's solicitor. The sombre housekeeper was a mere shadow in comparison; indeed, she seemed to efface herself and wait only on the butler, and Brown heard no more of those volcanic whispers which had half told him of the younger brother who blackmailed the elder. Whether the prince was really being thus bled by the absent captain, he could not be certain, but there was something insecure and secretive about Saradine that made the tale by no means incredible.
When they went once more into the long hall with the windows and the mirrors, yellow evening was dropping over the waters and the willowy banks; and a bittern sounded in the distance like an elf upon his dwarfish drum. The same singular sentiment of some sad and evil fairyland crossed the priest's mind again like a little grey cloud. "I wish Flambeau were back," he muttered.
"Do you believe in doom?" asked the restless Prince Saradine suddenly.
"No," answered his guest. "I believe in Doomsday."
The prince turned from the window and stared at him in a singular manner, his face in shadow against the sunset. "What do you mean?" he asked.
"I mean that we here are on the wrong side of the tapestry," answered Father Brown. "The things that happen here do not seem to mean anything; they mean something somewhere else. Somewhere else retribution will come on the real offender. Here it often seems to fall on the wrong person."
The prince made an inexplicable noise like an animal; in his shadowed face the eyes were shining queerly. A new and shrewd thought exploded silently in the other's mind. Was there another meaning in Saradine's blend of brilliancy and abruptness? Was the prince—Was he perfectly sane? He was repeating, "The wrong person—the wrong person," many more times than was natural in a social exclamation.
Then Father Brown awoke tardily to a second truth. In the mirrors before him he could see the silent door standing open, and the silent Mr. Paul standing in it, with his usual pallid impassiveness.
"I thought it better to announce at once," he said, with the same stiff respectfulness as of an old family lawyer, "a boat rowed by six men has come to the landing-stage, and there's a gentleman sitting in the stern."
"A boat!" repeated the prince; "a gentleman?" and he rose to his feet.
There was a startled silence punctuated only by the odd noise of the bird in the sedge; and then, before anyone could speak again, a new face and figure passed in profile round the three sunlit windows, as the prince had passed an hour or two before. But except for the accident that both outlines were aquiline, they had little in common. Instead of the new white topper of Saradine, was a black one of antiquated or foreign shape; under it was a young and very solemn face, clean shaven, blue about its resolute chin, and carrying a faint suggestion of the young Napoleon. The association was assisted by something old and odd about the whole get-up, as of a man who had never troubled to change the fashions of his fathers. He had a shabby blue frock coat, a red, soldierly looking waistcoat, and a kind of coarse white trousers common among the early Victorians, but strangely incongruous today. From all this old clothes-shop his olive face stood out strangely young and monstrously sincere.
"The deuce!" said Prince Saradine, and clapping on his white hat he went to the front door himself, flinging it open on the sunset garden.
By that time the new-comer and his followers were drawn up on the lawn like a small stage army. The six boatmen had pulled the boat well up on shore, and were guarding it almost menacingly, holding their oars erect like spears. They were swarthy men, and some of them wore earrings. But one of them stood forward beside the olive-faced young man in the red waistcoat, and carried a large black case of unfamiliar form.
"Your name," said the young man, "is Saradine?"
Saradine assented rather negligently.
The new-comer had dull, dog-like brown eyes, as different as possible from the restless and glittering grey eyes of the prince. But once again Father Brown was tortured with a sense of having seen somewhere a replica of the face; and once again he remembered the repetitions of the glass-panelled room, and put down the coincidence to that. "Confound this crystal palace!" he muttered. "One sees everything too many times. It's like a dream."
"If you are Prince Saradine," said the young man, "I may tell you that my name is Antonelli."
"Antonelli," repeated the prince languidly. "Somehow I remember the name."
"Permit me to present myself," said the young Italian.
With his left hand he politely took off his old-fashioned top-hat; with his right he caught Prince Saradine so ringing a crack across the face that the white top hat rolled down the steps and one of the blue flower-pots rocked upon its pedestal.
The prince, whatever he was, was evidently not a coward; he sprang at his enemy's throat and almost bore him backwards to the grass. But his enemy extricated himself with a singularly inappropriate air of hurried politeness.
"That is all right," he said, panting and in halting English. "I have insulted. I will give satisfaction. Marco, open the case."
The man beside him with the earrings and the big black case proceeded to unlock it. He took out of it two long Italian rapiers, with splendid steel hilts and blades, which he planted point downwards in the lawn. The strange young man standing facing the entrance with his yellow and vindictive
