Colonel Pound looked at him keenly, but the speaker's mild grey eyes were fixed upon the ceiling with almost empty wistfulness.
"A crime," he said slowly, "is like any other work of art. Don't look surprised; crimes are by no means the only works of art that come from an infernal workshop. But every work of art, divine or diabolic, has one indispensable mark—I mean, that the centre of it is simple, however much the fulfilment may be complicated. Thus, in Hamlet, let us say, the grotesqueness of the grave-digger, the flowers of the mad girl, the fantastic finery of Osric, the pallor of the ghost and the grin of the skull are all oddities in a sort of tangled wreath round one plain tragic figure of a man in black. Well, this also," he said, getting slowly down from his seat with a smile, "this also is the plain tragedy of a man in black. Yes," he went on, seeing the colonel look up in some wonder, "the whole of this tale turns on a black coat. In this, as in Hamlet, there are the rococo excrescences—yourselves, let us say. There is the dead waiter, who was there when he could not be there. There is the invisible hand that swept your table clear of silver and melted into air. But every clever crime is founded ultimately on some one quite simple fact—some fact that is not itself mysterious. The mystification comes in covering it up, in leading men's thoughts away from it. This large and subtle and (in the ordinary course) most profitable crime, was built on the plain fact that a gentleman's evening dress is the same as a waiter's. All the rest was acting, and thundering good acting, too."
"Still," said the colonel, getting up and frowning at his boots, "I am not sure that I understand."
"Colonel," said Father Brown, "I tell you that this archangel of impudence who stole your forks walked up and down this passage twenty times in the blaze of all the lamps, in the glare of all the eyes. He did not go and hide in dim corners where suspicion might have searched for him. He kept constantly on the move in the lighted corridors, and everywhere that he went he seemed to be there by right. Don't ask me what he was like; you have seen him yourself six or seven times tonight. You were waiting with all the other grand people in the reception room at the end of the passage there, with the terrace just beyond. Whenever he came among you gentlemen, he came in the lightning style of a waiter, with bent head, flapping napkin and flying feet. He shot out on to the terrace, did something to the table cloth, and shot back again towards the office and the waiters' quarters. By the time he had come under the eye of the office clerk and the waiters he had become another man in every inch of his body, in every instinctive gesture. He strolled among the servants with the absent-minded insolence which they have all seen in their patrons. It was no new thing to them that a swell from the dinner party should pace all parts of the house like an animal at the Zoo; they know that nothing marks the Smart Set more than a habit of walking where one chooses. When he was magnificently weary of walking down that particular passage he would wheel round and pace back past the office; in the shadow of the arch just beyond he was altered as by a blast of magic, and went hurrying forward again among the Twelve Fishermen, an obsequious attendant. Why should the gentlemen look at a chance waiter? Why should the waiters suspect a first-rate walking gentleman? Once or twice he played the coolest tricks. In the proprietor's private quarters he called out breezily for a syphon of soda water, saying he was thirsty. He said genially that he would carry it himself, and he did; he carried it quickly and correctly through the thick of you, a waiter with an obvious errand. Of course, it could not have been kept up long, but it only had to be kept up till the end of the fish course.
"His worst moment was when the waiters stood in a row; but even then he contrived to lean against the wall just round the corner in such a way that for that important instant the waiters thought him a gentleman, while the gentlemen thought him a waiter. The rest went like winking. If any waiter caught him away from the table, that waiter caught a languid aristocrat. He had only to time himself two minutes before the fish was cleared, become a swift servant, and clear it himself. He put the plates down on a sideboard, stuffed the silver in his breast pocket, giving it a bulgy look, and ran like a hare (I heard him coming) till he came to the cloak room. There he had only to be a plutocrat again—a plutocrat called away suddenly on business. He had only to give his ticket to the cloak-room attendant, and go out again elegantly as he had come in. Only—only I happened to be the cloak-room attendant."
"What did you do to him?" cried the colonel, with unusual intensity. "What did he tell you?"
"I beg your pardon," said the priest immovably, "that is where the story ends."
"And the interesting story begins," muttered Pound. "I think I understand his professional trick. But I don't seem to have got hold of yours."
"I must be going," said Father Brown.
They walked together along the passage to the entrance hall, where they saw the fresh, freckled face of the Duke of Chester, who was bounding buoyantly along towards them.
"Come along, Pound," he cried breathlessly. "I've been looking for you everywhere. The dinner's going again in spanking style, and old Audley has got to make a speech in honour of the forks being saved. We want to start some new ceremony, don't you know, to commemorate the occasion. I say, you really got the goods back, what do you suggest?"
"Why," said the colonel, eyeing him with a certain sardonic approval, "I should suggest that henceforward we wear green coats, instead of black. One never knows what mistakes may arise when one looks so like a waiter."
"Oh, hang it all!" said the young man, "a gentleman never looks like a waiter."
"Nor a waiter like a gentleman, I suppose," said Colonel Pound, with the same lowering laughter on his face. "Reverend sir, your friend must have been very smart to act the gentleman."
Father Brown buttoned up his commonplace overcoat to the neck, for the night was stormy, and took his commonplace umbrella from the stand.
"Yes," he said; "it must be very hard work to be a gentleman; but, do you know, I have sometimes thought that it may be almost as laborious to be a waiter."
And saying "Good evening," he pushed open the heavy doors of that palace of pleasures. The golden gates closed behind him, and he went at a brisk walk through the damp, dark streets in search of a penny omnibus.
The Flying Stars
"The most beautiful crime I ever committed," Flambeau would say in his highly moral old age, "was also, by a singular coincidence, my last. It was committed at Christmas. As an artist I had always attempted to provide crimes suitable to the special season or landscapes in which I found myself, choosing this or that terrace or garden for a catastrophe, as if for a statuary group. Thus squires should be swindled in long rooms panelled with oak; while Jews, on the other hand, should rather find themselves unexpectedly penniless among the lights and screens of the Cafe Riche. Thus, in England, if I wished to relieve a dean of his riches (which is not so easy as you might suppose), I wished to frame him, if I make myself clear, in the green lawns and grey towers of some cathedral town. Similarly, in France, when I had got money out of a rich and wicked peasant (which is almost impossible), it gratified me to get his indignant head relieved against a grey line of clipped poplars, and those solemn plains of Gaul over which broods the mighty spirit of Millet.
"Well, my last crime was a Christmas crime, a cheery, cosy, English middle-class crime; a crime of Charles Dickens. I did it in a good old middle-class house near Putney, a house with a crescent of carriage drive, a house with a stable by the side of it, a house with the name on the two outer gates, a house with a monkey tree. Enough, you know the species. I really think my imitation of Dickens's style was dexterous and literary. It seems almost a pity I repented the same evening."
Flambeau would then proceed to tell the story from the inside; and even from the inside it was odd. Seen from the outside it was perfectly
