High on the sun-scorched hillside above the steamy littoral of the Caribbean Sea the Spanish-Indian town of Rio Frio lay sweltering in the heat of afternoon. The flat-topped, white houses surrounding the plaza reflected a dazzling glare, and the heat shimmered mercilessly upon the rough paving-stones. Flakes of plaster had fallen from the buildings; a few of them were mere ruins, relics of a past age; for the town had been built when conquistadores from Spain first plunged into the tropic forest to search for El Dorado. Here and there dilapidated green lattices shaded upper windows, and nearer the ground narrow openings were guarded by rusty iron bars; but some of the houses showed blank outer walls, and the plaza had rather an Eastern than an American look. Spain has set upon the New World the stamp the Moors impressed on her.

At one end of the plaza stood the Café Four Nations, a low, open-sided room, with a row of decaying pillars dividing it from the pavement. It was filled with flies, which stuck in black clusters to the papers hanging from the tarnished lamps and crawled about the dusty tables. The hot air was tainted with aniseed, picadura tobacco, and the curious musky smell which is a characteristic of ancient Spanish towns. On the right-hand side of the square rose the twin towers of the church of San Sebastian. Wide steps led up to the patch of shadow where a leather curtain left uncovered part of the door, and a niche above sheltered an image of the martyr with an arrow in his breast. The figure was well modeled and grimly realistic.

Opposite the café, the calle Mercedes cut a cool, dark gap through the dazzling town. On its outskirts, the hillside fell sharply to a wide, green level. Beyond this a silver gleam indicated the sea.

The café was in shadow, and at its inner end a number of citizens lounged, half asleep, in low cane chairs. The hour of the siesta had slipped away, but it was not yet time for dinner, and, having read the newspaper and guardedly discussed politics, the leading inhabitants of Rio Frio had nothing else to do. They were men with formal manners, a few dressed in rusty black, and some in white cotton, but all were not of pure European blood. One or two, indeed, plainly showed their Negro descent; others the melancholy of the Indian aboriginal.

Near the front pillars, a priest and two men of lighter color were seated at a table. Father Agustin wore a threadbare cassock and clumsy rawhide shoes, but he had an air of quiet dignity, and his sharply cut features were of the Gothic type, which is not uncommon in Spain. His accent was also clean Peninsular. James Grahame, who sat opposite across the chessboard, wore the same vague but recognizable stamp of breeding, though his duck suit was getting ragged and his red silk sash was obviously cheap. He had steady gray eyes, and light hair, a rather prominent nose and a firm mouth. He looked older than his thirty years. The lines on his forehead hinted at stern experience, and his alertness was partly masked by an easy self-control. Walthew was younger, and dressed with scrupulous neatness in duck, with smart tan shoes. His face was mobile, his glance quick but open, and his mouth sensitive; he had the look of an aristocratic American.

Father Agustin made a deprecatory gesture as his thin, long-nailed hand moved across the board, and Grahame smiled.

"Yes," he said, filling the tiny glass before the priest, "it is mate this time, padre. When you had made a few moves I foresaw defeat, but while the candle burns one plays out the game."

"It is so, but not with all," Father Agustin replied in his fine Castilian. "The losing game needs courage."

"Experience helps. Getting beaten does not hurt so much when one grows used to it."

"Ah!" said the priest, "that is the way to the greatest victory man can win. But I am your guest, and will not moralize. I must compliment you on the game you play. It is bold and well thought out, but perhaps somewhat lacking in finesse."

"I am afraid finesse is not a virtue of mine," Grahame smiled.

Father Agustin studied him quietly. When the Briton spoke he lost something of his reserve. His glance got keen, and his eyes had a curious hawk-like look. The priest could imagine him as swift and determined in action; quick to seize an advantage, but not a good plotter.

"For all that, it is a quality that is useful when one deals with the Latins, at Rio Frio, or elsewhere," the priest said.

"With apologies, padre, that is certainly true," Walthew agreed.

"So you have some business here? Perhaps, like the others, you seek a mineral concession."

"No. Our host, Don Martin, is of course out of office and doesn't deal in them."

"He never will," the priest said quietly. "The natural wealth of this country belongs to its people, but it is stolen from them, piece by piece, and given to foreigners."

"The foreigners pay for what they get."

"Yes," said the priest; "but where does the money go? If it were spent on the development of the country, one would not complain; but it is gamblers and courtezans who benefit. Those who hold office here fill their pockets from the public purse, and what is left when they are satisfied is needed to keep the Government in power."

"Then, why do you not reform your administration and put in straight men?"

Father Agustin indicated the drowsy group at the back of the café.

"These are our politicians! They meet every day and ruminate over the affairs of the nation. Think of it!"

"Well," said Walthew, "they do not look busy; but things do happen here now and then."

"It is true. A clique breaks up, there is a new coalition, and those who plotted each other's downfall are united again. We Latins have seldom a continuous policy. Sometimes there is a tumult in the streets and disaffection among the troops; then the man who rules us uses the whip. One hears of no trial, but a malcontent is missing, an officer's duty takes him to the fever jungles, where he cannot live. Sometimes, before the morning mist has lifted, one is wakened by a volley in the ditch behind the citadel."

"You are a patient race," Grahame remarked.

"Not so," said Father Agustin. "We often dream when we should act, but sometimes we act too soon. It is our misfortune that we do not know how to wait for the right moment." He paused and indicated the thinned-out ranks of pawns on the chessboard. "It is like that in the game of politics! The fight is between the greater pieces, but these others fall."

Grahame lighted a cigarette and glanced about the square, for Rio Frio was waking up. Here and there a woman of mixed blood crouched beside a cast-iron pot, fanning the handful of charcoal in it, ready for cooking the evening meal. A team of mules hauled a heavy load across the hot paving stones, a gaunt, dark-faced man in ragged cotton walking at the leaders' heads. Then came a pack train, with jingling bells, a cloud of flies following the burdened animals, and dusty, barefooted peasants plodding by their side. A group of women appeared from the mouth of a narrow street, their faces wet with perspiration and straps across their foreheads supporting the big cane baskets on their backs. After them came a negro with a great tray of fruit upon his head. Next, three or four lean, barefooted fellows with ragged palm-leaf hats seated themselves on the pavement in a strip of shadow. They sat there, silent and motionless, contemplating the scene with listless eyes. The crowd looked dully apathetic, there was languor in the air they breathed; but, after all, they claimed descent from Spanish stock and Grahame thought they could be roused. It does not need much fanning to wake the smoldering fire in the Iberian's veins.

"My sheep!" said Father Agustin. "But they have other shepherds, who do not always lead them well."

"Shear the flock instead of guarding it? One would imagine that there is not much wool."

"None is so poor that he has nothing to give; if not goods, his voice, his sullen clamor and savage rage. The unthinking passion of the mob is terrible, but it is used by those who must answer for the deed some day. My people have their wrongs, but one cannot build the State on foundations of revenge and cruelty."

"But you have some honest men who hate the present Government."

"It is possible that their honesty lessens their influence. At Rio Frio one does not follow the ideal. It is remote and elusive; the feet get weary, and many things that please the eye lie nearer to hand." Father Agustin rose and bowed with grave courtesy. "And now I have talked enough and have some duties. I thank you and take my leave."

They watched him cross the plaza in his rusty cassock.

"Guess we've struck the wrong place," Walthew said. "We're more likely to find trouble than money here. Well, there's a prospect of new experiences and a little excitement; and, anyway, we can't go back on our bargain with Don Martin."

"I never quite understood what led you to join me," Grahame remarked. "You know the risk we run. If the Government catches us, we'll be hanged or shot – whichever suits their fancy."

Walthew laughed.

"That's the attraction. But we won't be caught. I guess my Yankee ingenuity will count for something. If these sleepy-looking dagoes should trap us, we can find a way to give 'em the slip."

"Optimism is a great asset," Grahame smiled; "but in this country it must have a handmaiden – a convenient revolver."

Walthew leaned forward on the table.

"We've gone into a risky business together. I know nothing about you except that you seem to understand these dagoes and are a handy man to have around when they pull their knives. You know almost nothing about me."

He paused and smiled, and Grahame stirred uneasily. Walthew looked so boyish when he smiled like that. Would he have that carefree look in, say, two months? At times, Grahame regretted letting the boy join him in a venture that might try the heart of even a very strong man.

"I say, old chap, you aren't listening!" Walthew expostulated. "I'm telling you that the pater's a money-making machine. When I left Harvard he was for working me up into a partnership in the Walthew factory. But I couldn't stand it – too monotonous. I took ten thousand dollars, instead, on condition that if I hadn't made good in my own way when two years were up, I'd go back and start as clerk."

"Well," Grahame returned with a smile, "I haven't much to tell. I have no family business to fall back on. As my means were not large enough to let me live as I liked at home, I went abroad to increase them. So far I haven't succeeded; but, on the whole, I've had a pretty good time, and I don't see much reason for grumbling about my luck."

This was correct, so far as it went, for Grahame did not think it worth while to explain that the fiery blood of the Borderers ran in his veins and his people had been soldiers and explorers until economic changes impoverished the family. Nor could he add that, because his name still counted for something in the North, he had left home to avoid being skilfully led into a marriage his friends thought suitable. He had, indeed, run away from a well-born girl with money, who, he suspected, was relieved to see him go. Since then he had known trouble, and it had hardened him. Yet he was honest and was marked by some polish.

At first sight, and by contrast with his comrade, Walthew looked callow, but he improved on acquaintance. It was not for nothing that he was the son of a shrewd manufacturer, who had built up a great business from a humble beginning. Walthew was cool in a crisis, and though outwardly careless, he was capable of looking ahead. So far, his talents were undeveloped, but Grahame suspected them.

While they sat talking, the scene in the square gained animation. Groups of men, moving quickly, emerged from the side streets; there was a murmur of voices; and a crowd began to gather. Women called from the flat housetops; doors were opened and naked, dark-skinned children dragged in from the pavement. The concourse thickened about the steps of the church; gesticulating men chattered in the native patois.

Grahame's eyes grew keen.

"Something's going to happen," he said quietly.

Then he pressed his comrade's arm as a man appeared on the highest step of the church, and the murmur of the crowd swelled into a roar:

"Viva Castillo! Viva el libertador!"

The tall figure bowed and held up a hand, and for a moment there was silence; then a clear voice rang out, and Grahame tried to catch the sonorous Castilian words. He was too far off, and some escaped him, but he heard enough to gather that it was a grim indictment of the rulers of the country. The man spoke with fire and passion, using lavish gestures, and the cries that answered showed that he could work upon the feelings of the crowd.

The café had emptied, and its stout proprietor lounged, napkin in hand, near Grahame's table.

"Sounds pretty drastic, if I heard him right," Walthew remarked. "It's obvious that the authorities don't use half-measures. Did he say they had the deputation arrested and its leader shot?"

"So I understood," said Grahame. "How did you come to learn Castilian?"

"A notion of the old man's; he made me study languages. It's his ambition to ship the Walthew manufactures all over the world, and he got a footing in Cuba some time ago."

They were silent for a few minutes, and then Grahame turned to the landlord.

"Are these things true?"

"It is possible," the other answered cautiously.

"Then are you not afraid of a revolution?"

"No, señor; why should I fear? When there is a revolution the wine trade is good."

"But suppose your customers get killed?"

The landlord smiled.

"They are philosophic politicians, señor. It is the untaught rabble that fights. These others drink their wine and argue over the newspapers. Besides, there will be no revolution yet. Some talk, perhaps; possibly a supporter of the Government stabbed in the dark."

"And that will be all?" Grahame asked with a keen glance.

"There will be nothing more. The President waits and watches until he knows his enemies. Then he gives an order and there is an end of them."

The man turned away, and when, shortly afterward, the plaza rang with fierce applause, a voice was raised in alarm. Others joined in, the crowd began to stream back from the steps, and the orator disappeared. Then the mass broke into running groups, and through the patter of their feet there came a steady, measured tread. It drew nearer; short, swarthy men in dirty white uniforms marched into the plaza, the strong light gleaming on their rifles. They wheeled and stopped in ranks extended across the square, and the rifles went up to their shoulders. Warning shouts fell from the roofs, the patter of feet grew faster, the shadowy streets were choked with fugitives, and the place was empty except for the line of quiet men. Then an officer laughed and called out, and the rifles came down with a clang.

"I suspect that we're up against a big man in the President," Walthew remarked. "Perhaps we'd better light out before these fellows ask us questions."

CHAPTER II
THE ADVENTURES BEGIN

A half moon hung over the flat roofs and the air was very still. Walthew and Grahame sat on a balcony surrounding the patio of Don Martin Sarmiento's house. The lattice windows that opened onto the balcony had old but artistic hinges of bronze, and the crumbling hardwood rails showed traces of skilful carving. Below, a small fountain splashed in a marble basin surrounded by palmettos, and a creeper covered a trellis with trails of dusky purple. A faint smell of decay mingled with the more pungent odors of garlic and olive oil from the kitchen in the courtyard, where a clatter was going on, but no sound from outside broke the silence. Rio Frio was very quiet now.

Cups of black coffee and a plate of fruit stood on a table in front of the men, and the señorita Blanca Sarmiento sat in a low chair opposite, with her duenna a few yards away. Blanca was then nineteen, and Walthew, watching her with unobtrusive admiration, wondered how it was that her relatives had not already arranged a marriage for her, unless, perhaps, her father's political opinions stood in the way. One ran a risk in opposing the Government at Rio Frio. The girl was attractive, with a finely molded figure, the grace of which was displayed by her languid pose. Her hair was dark and coiled in heavy masses on a small, well-shaped head; her lips were full and very red, but her eyes were a deep blue and her skin fairer than that of the Spanish-American women Walthew hitherto had met. Nor did she use the powder they lavishly employ.

With a crimson rose in her hair, and a fine black-lace mantilla draped about her shoulders and emphasizing the whiteness of her neck and half-covered arms, she reminded Walthew of Carmen. She had something of the latter's allurement, but he thought it was an unconscious attraction that she exercised. The art of the coquette was missing; the girl had a certain dignity, and there was no hint of sensuality in her beauty. She had, no doubt, Spanish fire in her blood, but the lad thought it burned with a clear and pure flame.

"How do you come to speak English so charmingly?" he asked, in the hope of satisfying his curiosity about her.

"Do I speak it charmingly?" She laughed prettily. "Well, the explanation is that it was my mother's tongue. She was Irish, you must know."

"Ah!" said Walthew. "Now I understand."

Blanca gave him a glance of languid amusement.

"Your interest is flattering, señor; but what is it you understand?"

"That's an awkward question," Walthew answered, grinning frankly. "Still, there's something about you that I haven't noticed in Spanish-American girls, charming as they are."

"I'm afraid you're evasive. Do you know many of my countrywomen?"

"I'd like to know more. But I believe I'm good at reading character. It is a gift I inherited. My father was never mistaken about a man, and he has made use of a good many."

Blanca studied him. He had a smooth, fresh face, and looked very young, but while she thought he was direct and perhaps impulsive, something suggested that he was shrewd.

"Women are supposed to be more puzzling," she answered. "Then the Sarmientos come from Andalusia, and the Peninsulares are complex people. On the surface, we are often cheerfully inconsequent, but underneath there's a strain of melancholy. We live in the shadow of a fatalism we got from the Moors." She glanced at Grahame. "I think you can understand."

Grahame made a sign of assent. Sitting thoughtfully silent, his lean but powerful frame displayed by the thin white duck, and his strong, brown face impassive, he had a somber look. The man was reckless and sparkled with gay humor now and then, but it was the passing brightness of the North.

"Yes," he said, "I understand. But the Irish are optimists, and you are Irish too."

"Then perhaps that's why I keep hopeful. It is not always easy at Rio Frio, and life was not very joyous when we were exiles in America."

"You know my country?" Walthew broke in.

"I know your Southern States. We lived there in poverty, wandering up and down. My father is what his friends call a patriot, and his enemies a dangerous agitator. He had to choose between ruin and acquiescence in corrupt tyranny, and his course was plain. But the seed he had sown sprouted, the dictator was driven out, and we came back to our own. Then, for a time, there was rest and safety, until the new ruler began to follow the old. He tried to bribe my father, who had helped to put him in power; but our honor was not for sale, and we had to leave the capital. There are men who trust my father, and look to him for help… But I think you know something of this."

"Yes," said Grahame. "This afternoon we heard Castillo speak in the plaza."

The girl's eyes flashed angrily.

"Castillo is a fool! He pulls down what others have carefully built up."

"Tries to fire the mine before things are ready?" Walthew suggested. "A premature explosion's apt to blow up the men who prepared it."

Blanca gave him a keen glance.

"That is what nearly happened this afternoon. I believe you are to be trusted, señores?"

Grahame bowed.

"I am an adventurer, not a patriot, and my partner is out for money, but we made a bargain with Don Martin and we keep our word."

"Then," said the girl quietly, "Castillo is hiding here."

"In the casa Sarmiento! Isn't that dangerous? Won't the President's friends suspect?"

"I think they do, but they are afraid of my father's hold on the people; and there is only a handful of troops. When it is late they may make a search, but Castillo will leave soon. It is possible that you are in some danger."

Walthew laughed.

"That makes things interesting; I've never been in serious danger yet. But I suppose you have Don Martin's permission to be frank with us?"

"You are shrewd," she answered, smiling. "He has some confidence in my judgment. I spent the years that should have been happiest in poverty and loneliness. Are you surprised that I'm a conspirator? If you value your safety, you will beware of me."

"You might prove dangerous to your enemies, but I believe you'd be very staunch to your friends."

"Gracias, señor. I'm sure I can at least hate well."

A mulatto boy came out on to the balcony, and the girl's stout duenna, who had been sitting silent and apparently half asleep, rose and approached the table.

"Don Martin is disengaged," she said to Blanca; and when the girl waited a moment Grahame imagined that something had been left for her to decide.

He did not see any sign exchanged, but he thought with some amusement that he and his companion had passed a test when the duenna said to them:

"Don Martin would speak with you."

Walthew turned to Blanca, saying in Castilian:

"Until our next meeting! I kiss your hands, señorita."

The girl rose with a grave curtsy and there was a touch of stateliness in her manner.

"May you go in safety, señores! We expect much from you."

The mulatto led them away, and, passing through the house, they found their host and another man sitting by a dim lamp in a room with the shutters carefully closed. Don Martin Sarmiento wore an alpaca jacket, a white shirt, and a black silk sash round the waist of his duck trousers. He was dark-haired and sallow, lightly built and thin, but his expression was eager and his eyes were penetrating. One could have imagined that his fiery spirit had worn down the flesh.

The other man was of coarser type. His skin was very dark, his face hot and fleshy, and Grahame noticed that his hands were wet with perspiration. His glance was restless and he had a rather truculent air, though there was something in it that hinted at uneasiness. Grahame thought that while he might show a rash boldness now and then, his nerve was not very good.

"With your permission, I present my comrade, Señor Castillo," said Don Martin. "Should any disaster overtake me, Señor Castillo, or another whom he appoints, will carry out our contract. Our funds are in safe hands; the rifles will be paid for."

"They will be delivered," Grahame answered quietly.

"Good! The word of a gentleman is sufficient. And now there is something more to be said. My house is my friend's, particularly if he is in trouble, but one has higher duties than hospitality."

"Yes," agreed Grahame, turning to Castillo. "The interests of one's country come first. There are only three of us, and Don Martin is the head of an important organization."

"It was not for my personal safety that I came here," Castillo broke in hotly. "I carried papers; lists of names, compromising details. It was unthinkable that they should fall into the President's hands. They must be made safe, and then it does not matter what happens to me – though I may, perhaps, claim to have been of some help to the cause of freedom."

Grahame saw his host's half-impatient smile.

"And so you gave them to Don Martin!" he remarked dryly.

"He is not watched as I am," Castillo answered. "I am hunted among the sierras, I hide in the fever swamps; but where I pass I leave a spark that tyranny cannot trample out. It burns and spreads; by and by there comes the purging conflagration."

"Yes," said Grahame. "I'm told, however, that your President has a keen scent for smoke, and I don't mean to scatter more sparks than I can help." He turned to Don Martin. "Since our business is finished, we can leave Rio Frio in an hour."

"I, too!" exclaimed Castillo. "It is not good for the cause that the soldiers find me. But there are difficulties; the house may be watched."

Don Martin looked thoughtful, but not disturbed; and Grahame saw that he could calmly take a risk. Danger and his host obviously were old acquaintances.

"It is better that you go," he answered. "Sometimes I entertain an American traveler, and Englishmen now and then visit Rio Frio. I do not think you are suspected yet, and you may be able to help us by drawing off the watchers' attention when you leave. We will see what can be done, but it would be safer for Señor Castillo not to come with us."

He took the others to the roof, where he walked to the edge and looked over the low parapet. A narrow, dark street divided Sarmiento's house from the next, but a lattice in a high wall was open, and Grahame imagined that he made out a man's head, which was, however, promptly withdrawn.

"Once or twice a guest of mine has reached the calle by a rope, but the President's friends take precautions to-night," Don Martin remarked. "There remain the windows on the other side, but Castillo is heavy and fat. I think the door into the plaza would suit him best."

"Wouldn't the small one at the back be safer?" Walthew suggested.

"That will be watched, but it might be of some help if you went that way. Possibly you would not mind wearing a sombrero and a Spanish cloak."

"Not at all," Grahame assured him. "Still, there are two of us."

"That is an advantage. If one leaves shortly after the other, those who keep watch and expect a single man will be puzzled."

Walthew chuckled.

"Good! I'd a hankering after adventures, and now it looks as if I'd be gratified. But you had better not give us clothes with a name on them."

"In this country, people out of favor with the Government are modest about their names," Don Martin rejoined.

Ten minutes later Grahame, wearing a wide black hat and a dark Spanish cloak, stepped quietly out into the shadowy street. He had seen that his automatic pistol was ready to his hand, having had more than one experience of the half-breed's dexterity with the silent knife. For all that, his hurried, stealthy gait was assumed and not natural to the man, whose heart beat calmly, though he cast quick glances about. The houses were high, and the street seemed to get narrower and darker as he went on. Then he imagined he heard soft steps behind him. Walking faster, he stopped at a corner and listened. Somebody was certainly following him.

Grahame's first impulse was to hide in a dark doorway and wait for his pursuer, but he reflected that this would not fall in with his host's plan, and he went on, keeping in the shadow while he made for the hotel at which he had left his mules. There were, he imagined, two men following him now.

A few moments afterward he reached the end of the dark street, and the empty plaza lay before him. The moon shed a faint light upon the stones and the high, white walls, and Grahame was glad of this. Now, if it were needful, he could defend himself: the walk through the shadow had been trying. Still, he must not hurry, for he never promised more than he meant to perform, and he knew that Don Martin relied upon his playing out his part. Perhaps he overdid it when he stopped to light a cigarette, for, looking up as he dropped the match, he saw two dark figures stop at the corner he had left. Then there was a low whistle, and one of them disappeared. Grahame smiled, because he knew that Walthew had divided the attention of the spies. The remaining man, however, walked quickly after him, and when Grahame was half way across the plaza he waited. His pursuer seemed to hesitate, for he came on more slowly, and stopped a few yards off.

"The American!" he exclaimed.

"English," said Grahame calmly. "The difference is, no doubt, not important."

The man looked hard at him, and Grahame carelessly dropped his hand upon his pistol.

"I am going to the fonda; if you are going that way, I would rather you walked in front. One is careful at night, my friend."

Though the fellow had a sinister look, he smiled and went off with an apology, and Grahame, going on to the hotel, waited outside until Walthew came up. The boy looked hot and breathless, but Grahame noticed that he had a flower in his hand.

"I've been followed," Walthew laughed. "The fellows dropped back soon after I came into the moonlight. Guess they saw they were after the wrong man."

"Very possibly. It happened to me. I wonder whether Castillo got away?"

They listened, but the town was quiet. One or two citizens crossed the plaza, but no sound that indicated anything unusual going on rose from the shadowy streets.

"It seems likely," Walthew replied. "I don't think they could have arrested him without some disturbance. Why didn't they search Sarmiento's house?"

"Perhaps they were afraid of starting a riot that would spread. The President seems to be a capable man, and Don Martin obviously enjoys the confidence of the citizens. On the whole, I think he deserves it."

"So do I," Walthew agreed. "What do you think of the other fellow?"

"I wouldn't trust him. He's no doubt sincere, but I'm not sure of his nerve. But where did you get the rose?"

"On the pavement outside the casa Sarmiento," Walthew answered with some embarrassment.

"Mmm! Dropped from a window. Such things happen in Spanish-American towns, and it's possible that the President's spies have noted it against you. However, you'll be too busy to think of the señorita when we get back to the coast." Grahame paused and added: "It might be wise to remember that you're engaged in a dangerous business, and can't run the risk of any complications. Neither of us can indulge in philandering until this job's finished."
