As the little priest's words lengthened and lost themselves in a dull and dreamy sincerity, Muscari, whose animal senses were alert and impatient, heard a new noise in the mountains. Even for him the sound was as yet very small and faint; but he could have sworn the evening breeze bore with it something like the pulsation of horses' hoofs and a distant hallooing.
At the same moment, and long before the vibration had touched the less-experienced English ears, Montano the brigand ran up the bank above them and stood in the broken hedge, steadying himself against a tree and peering down the road. He was a strange figure as he stood there; for he had assumed a flapped fantastic hat and swinging baldric and cutlass in his capacity of bandit king, but the bright prosaic tweed of the courier showed through in patches all over him.
The next moment he turned his olive, sneering face and made a movement with his hand. The brigands scattered at the signal, not in confusion, but in what was evidently a kind of guerrilla discipline. Instead of occupying the road along the ridge, they sprinkled themselves along the side of it behind the trees and the hedge, as if watching unseen for an enemy. The noise beyond grew stronger, beginning to shake the mountain road, and a voice could be clearly heard calling out orders. The brigands swayed and huddled, cursing and whispering, and the evening air was full of little metallic noises as they cocked their pistols, or loosened their knives, or trailed their scabbards over the stones. Then the noises from both quarters seemed to meet on the road above; branches broke, horses neighed, men cried out.
"A rescue!" cried Muscari, springing to his feet and waving his hat; "the gendarmes are on them! Now for freedom and a blow for it! Now to be rebels against robbers! Come, don't let us leave everything to the police; that is so dreadfully modern. Fall on the rear of these ruffians. The gendarmes are rescuing us; come, friends, let us rescue the gendarmes!"
And throwing his hat over the trees, he drew his cutlass once more and began to escalade the slope up to the road. Frank Harrogate jumped up and ran across to help him, revolver in hand, but was astounded to hear himself imperatively recalled by the raucous voice of his father, who seemed to be in great agitation.
"I won't have it," said the banker in a choking voice; "I command you not to interfere."
"But, father," said Frank very warmly, "an Italian gentleman has led the way. You wouldn't have it said that the English hung back."
"It is useless," said the older man, who was trembling violently, "it is useless. We must submit to our lot."
Father Brown looked at the banker; then he put his hand instinctively as if on his heart, but really on the little bottle of poison; and a great light came into his face like the light of the revelation of death.
Muscari meanwhile, without waiting for support, had crested the bank up to the road, and struck the brigand king heavily on the shoulder, causing him to stagger and swing round. Montano also had his cutlass unsheathed, and Muscari, without further speech, sent a slash at his head which he was compelled to catch and parry. But even as the two short blades crossed and clashed the King of Thieves deliberately dropped his point and laughed.
"What's the good, old man?" he said in spirited Italian slang; "this damned farce will soon be over."
"What do you mean, you shuffler?" panted the fire-eating poet. "Is your courage a sham as well as your honesty?"
"Everything about me is a sham," responded the ex-courier in complete good humour. "I am an actor; and if I ever had a private character, I have forgotten it. I am no more a genuine brigand than I am a genuine courier. I am only a bundle of masks, and you can't fight a duel with that." And he laughed with boyish pleasure and fell into his old straddling attitude, with his back to the skirmish up the road.
Darkness was deepening under the mountain walls, and it was not easy to discern much of the progress of the struggle, save that tall men were pushing their horses' muzzles through a clinging crowd of brigands, who seemed more inclined to harass and hustle the invaders than to kill them. It was more like a town crowd preventing the passage of the police than anything the poet had ever pictured as the last stand of doomed and outlawed men of blood. Just as he was rolling his eyes in bewilderment, he felt a touch on his elbow, and found the odd little priest standing there like a small Noah with a large hat, and requesting the favour of a word or two.
"Signor Muscari," said the cleric, "in this queer crisis personalities may be pardoned. I may tell you without offence of a way in which you will do more good than by helping the gendarmes, who are bound to break through in any case. You will permit me the impertinent intimacy, but do you care about that girl? Care enough to marry her and make her a good husband, I mean?"
"Yes," said the poet quite simply.
"Does she care about you?"
"I think so," was the equally grave reply.
"Then go over there and offer yourself," said the priest: "offer her everything you can; offer her heaven and earth if you've got them. The time is short."
"Why?" asked the astonished man of letters.
"Because," said Father Brown, "her Doom is coming up the road."
"Nothing is coming up the road," argued Muscari, "except the rescue."
"Well, you go over there," said his adviser, "and be ready to rescue her from the rescue."
Almost as he spoke the hedges were broken all along the ridge by a rush of the escaping brigands. They dived into bushes and thick grass like defeated men pursued; and the great cocked hats of the mounted gendarmerie were seen passing along above the broken hedge. Another order was given; there was a noise of dismounting, and a tall officer with cocked hat, a grey imperial, and a paper in his hand appeared in the gap that was the gate of the Paradise of Thieves. There was a momentary silence, broken in an extraordinary way by the banker, who cried out in a hoarse and strangled voice, "Robbed! I've been robbed!"
"Why, that was hours ago," cried his son in astonishment: "when you were robbed of two thousand pounds."
"Not of two thousand pounds," said the financier, with an abrupt and terrible composure, "only of a small bottle."
The policeman with the grey imperial was striding across the green hollow. Encountering the King of the Thieves in his path, he clapped him on the shoulder with something between a caress and a buffet and gave him a push that sent him staggering away. "You'll get into trouble, too," he said, "if you play these tricks."
Again to Muscari's artistic eye it seemed scarcely like the capture of a great outlaw at bay. Passing on, the policeman halted before the Harrogate group and said: "Samuel Harrogate, I arrest you in the name of the law for embezzlement of the funds of the Hull and Huddersfield Bank."
The great banker nodded with an odd air of business assent, seemed to reflect a moment, and before they could interpose took a half turn and a step that brought him to the edge of the outer mountain wall. Then, flinging up his hands, he leapt exactly as he leapt out of the coach. But this time he did not fall into a little meadow just beneath; he fell a thousand feet below, to become a wreck of bones in the valley.
The anger of the Italian policeman, which he expressed volubly to Father Brown, was largely mixed with admiration. "It was like him to escape us at last," he said. "He was a great brigand if you like. This last trick of his I believe to be absolutely unprecedented. He fled with the company's money
