Yet, as he began to think steadily, the very blackness of his cell seemed to make his thoughts more vivid; he began to see as in a kind of vision the fantastic feet capering along the corridor in unnatural or symbolic attitudes. Was it a heathen religious dance? Or some entirely new kind of scientific exercise? Father Brown began to ask himself with more exactness what the steps suggested. Taking the slow step first: it certainly was not the step of the proprietor. Men of his type walk with a rapid waddle, or they sit still. It could not be any servant or messenger waiting for directions. It did not sound like it. The poorer orders (in an oligarchy) sometimes lurch about when they are slightly drunk, but generally, and especially in such gorgeous scenes, they stand or sit in constrained attitudes. No; that heavy yet springy step, with a kind of careless emphasis, not specially noisy, yet not caring what noise it made, belonged to only one of the animals of this earth. It was a gentleman of western Europe, and probably one who had never worked for his living.
Just as he came to this solid certainty, the step changed to the quicker one, and ran past the door as feverishly as a rat. The listener remarked that though this step was much swifter it was also much more noiseless, almost as if the man were walking on tiptoe. Yet it was not associated in his mind with secrecy, but with something else—something that he could not remember. He was maddened by one of those half-memories that make a man feel half-witted. Surely he had heard that strange, swift walking somewhere. Suddenly he sprang to his feet with a new idea in his head, and walked to the door. His room had no direct outlet on the passage, but let on one side into the glass office, and on the other into the cloak room beyond. He tried the door into the office, and found it locked. Then he looked at the window, now a square pane full of purple cloud cleft by livid sunset, and for an instant he smelt evil as a dog smells rats.
The rational part of him (whether the wiser or not) regained its supremacy. He remembered that the proprietor had told him that he should lock the door, and would come later to release him. He told himself that twenty things he had not thought of might explain the eccentric sounds outside; he reminded himself that there was just enough light left to finish his own proper work. Bringing his paper to the window so as to catch the last stormy evening light, he resolutely plunged once more into the almost completed record. He had written for about twenty minutes, bending closer and closer to his paper in the lessening light; then suddenly he sat upright. He had heard the strange feet once more.
This time they had a third oddity. Previously the unknown man had walked, with levity indeed and lightning quickness, but he had walked. This time he ran. One could hear the swift, soft, bounding steps coming along the corridor, like the pads of a fleeing and leaping panther. Whoever was coming was a very strong, active man, in still yet tearing excitement. Yet, when the sound had swept up to the office like a sort of whispering whirlwind, it suddenly changed again to the old slow, swaggering stamp.
Father Brown flung down his paper, and, knowing the office door to be locked, went at once into the cloak room on the other side. The attendant of this place was temporarily absent, probably because the only guests were at dinner and his office was a sinecure. After groping through a grey forest of overcoats, he found that the dim cloak room opened on the lighted corridor in the form of a sort of counter or half-door, like most of the counters across which we have all handed umbrellas and received tickets. There was a light immediately above the semicircular arch of this opening. It threw little illumination on Father Brown himself, who seemed a mere dark outline against the dim sunset window behind him. But it threw an almost theatrical light on the man who stood outside the cloak room in the corridor.
He was an elegant man in very plain evening dress; tall, but with an air of not taking up much room; one felt that he could have slid along like a shadow where many smaller men would have been obvious and obstructive. His face, now flung back in the lamplight, was swarthy and vivacious, the face of a foreigner. His figure was good, his manners good humoured and confident; a critic could only say that his black coat was a shade below his figure and manners, and even bulged and bagged in an odd way. The moment he caught sight of Brown's black silhouette against the sunset, he tossed down a scrap of paper with a number and called out with amiable authority: "I want my hat and coat, please; I find I have to go away at once."
Father Brown took the paper without a word, and obediently went to look for the coat; it was not the first menial work he had done in his life. He brought it and laid it on the counter; meanwhile, the strange gentleman who had been feeling in his waistcoat pocket, said laughing: "I haven't got any silver; you can keep this." And he threw down half a sovereign, and caught up his coat.
Father Brown's figure remained quite dark and still; but in that instant he had lost his head. His head was always most valuable when he had lost it. In such moments he put two and two together and made four million. Often the Catholic Church (which is wedded to common sense) did not approve of it. Often he did not approve of it himself. But it was real inspiration—important at rare crises—when whosoever shall lose his head the same shall save it.
"I think, sir," he said civilly, "that you have some silver in your pocket."
The tall gentleman stared. "Hang it," he cried, "if I choose to give you gold, why should you complain?"
"Because silver is sometimes more valuable than gold," said the priest mildly; "that is, in large quantities."
The stranger looked at him curiously. Then he looked still more curiously up the passage towards the main entrance. Then he looked back at Brown again, and then he looked very carefully at the window beyond Brown's head, still coloured with the after-glow of the storm. Then he seemed to make up his mind. He put one hand on the counter, vaulted over as easily as an acrobat and towered above the priest, putting one tremendous hand upon his collar.
"Stand still," he said, in a hacking whisper. "I don't want to threaten you, but——"
"I do want to threaten you," said Father Brown, in a voice like a rolling drum, "I want to threaten you with the worm that dieth not, and the fire that is not quenched."
"You're a rum sort of cloak-room clerk," said the other.
"I am a priest, Monsieur Flambeau," said Brown, "and I am ready to hear your confession."
The other stood gasping for a few moments, and then staggered back into a chair.
The first two courses of the dinner of The Twelve True Fishermen had proceeded with placid success. I do not possess a copy of the menu; and if I did it would not convey anything to anybody. It was written in a sort of super-French employed by cooks, but quite unintelligible to Frenchmen. There was a tradition in the club that the hors d'oeuvres should be various and manifold to the point of madness. They were taken seriously because they were avowedly useless extras, like the whole dinner and the whole club. There was also a tradition that the soup course should be light and unpretending—a sort of simple and austere vigil for the feast of fish that was to come. The talk was that strange, slight talk which governs the British Empire, which governs it in secret, and yet would scarcely enlighten an ordinary Englishman even if he could overhear it. Cabinet ministers on both sides were alluded to by their Christian names with a sort of bored benignity. The Radical Chancellor of the Exchequer, whom the whole Tory party was supposed to be cursing for his extortions, was praised for his minor poetry, or his saddle in the
