"There isn't a good one," she hissed. "There was badness enough in the captain taking all that money, but I don't think there was much goodness in the prince giving it. The captain's not the only one with something against him."
A light dawned on the cleric's averted face, and his mouth formed silently the word "blackmail." Even as he did so the woman turned an abrupt white face over her shoulder and almost fell. The door had opened soundlessly and the pale Paul stood like a ghost in the doorway. By the weird trick of the reflecting walls, it seemed as if five Pauls had entered by five doors simultaneously.
"His Highness," he said, "has just arrived."
In the same flash the figure of a man had passed outside the first window, crossing the sunlit pane like a lighted stage. An instant later he passed at the second window and the many mirrors repainted in successive frames the same eagle profile and marching figure. He was erect and alert, but his hair was white and his complexion of an odd ivory yellow. He had that short, curved Roman nose which generally goes with long, lean cheeks and chin, but these were partly masked by moustache and imperial. The moustache was much darker than the beard, giving an effect slightly theatrical, and he was dressed up to the same dashing part, having a white top hat, an orchid in his coat, a yellow waistcoat and yellow gloves which he flapped and swung as he walked. When he came round to the front door they heard the stiff Paul open it, and heard the new arrival say cheerfully, "Well, you see I have come." The stiff Mr. Paul bowed and answered in his inaudible manner; for a few minutes their conversation could not be heard. Then the butler said, "Everything is at your disposal"; and the glove-flapping Prince Saradine came gaily into the room to greet them. They beheld once more that spectral scene—five princes entering a room with five doors.
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 to-day. 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
