"The first thing is to see about the boatmen," the captain said. "Of course if they tell the authorities they brought a wounded man on board here late last night there is an end of it; but if they hold their tongues, and we all keep our own council, the thing may not leak out to-day, and we will have our anchor up and get out this evening if we can. You had better tell all the crew that not a word is to be said about the matter, and I will impress the same on the passengers. When they know that a careless word may lead to a month's detention, you may be sure there will be no talking. But before you speak to them I will go down and see Mr. Atherton, and hear what he says about the boatmen." He returned in two or three minutes. "I hope it will be all right," he said. "Atherton gave them a pound apiece, and told them to hold their tongues. He thinks it is probable they will do so, for they would know well enough that they would, as likely as not, be clapped into prison and kept there while the investigation was going on. So there is a strong hope that it may not leak out through them. You must stop all leave ashore, Mr. Ryan. Tell the men whose turn it is to go, they shall have their spree at Buenos Ayres. If they were to get drunk it would be as likely as not to slip out."

"I will see to it, sir."

Directly breakfast was over the captain took a boat and went ashore. He had duly impressed upon all the passengers the absolute necessity for silence, and several of these went ashore with him. He returned half an hour later, having been up to the British Consulate.

"The affair is making quite a stir in the town. Not on account of two men being found dead, there is nothing uncommon in that, especially as they have been recognized as two notorious ruffians; but the whole circumstances of the affair puzzle them.

"The doctors who have examined the bodies have arrived pretty well at the truth, and say that both men have been gripped by the throat, for the marks of the fingers are plainly visible, and their heads dashed together. But although this is, as we know, perfectly true, no one believes it; for the doctors themselves admit that it does not appear to them possible that any man would have had the strength requisite to completely batter in the skulls of two others, as has been done in this case. The police are searching the town for the man whose footsteps led in that direction, and as they know all the haunts of these ruffians and their associates it is likely enough that they will find him, especially as his face is sure to bear marks of Atherton's handiwork. Still, if they do find him, and he tells all he knows of the business, they will not be much nearer to tracing the actors in it to this ship. It is not probable that he recovered his senses until long after they were on board the boat, and can only say that while engaged in attempting to rob some passers-by he was suddenly knocked down. But even this they are not likely to get out of him first, for he will know that he used a knife, and is not likely to put himself in the way of punishment if he can help it. I came off at once, because I heard at the Consulate that the police are going to search every ship in the harbour to see if they can find some wounded man, or get some clue to the mystery, so I must ask the doctor if his two patients are fit to be dressed and go up on deck."

The doctor on being consulted said that he should certainly have preferred that they should have remained quiet all day, but he did not know that it would do them any harm to get on deck for a bit. And accordingly in half an hour Mr. Atherton and James Allen came up. The doctor, who had assisted them to dress, accompanied them.

"Now, Mr. Atherton, you had better seat yourself in that great deck-chair of yours with the leg-rest. If you sit there quietly reading when they come on board they are not likely to suspect you of being a desperate character, or to appreciate your inches and width of shoulder. Allen had better sit quiet till they get alongside, and then slip that sling into his pocket and walk up and down talking to one of the ladies, with his thumb in his waistcoat so as to support his arm. He looks pale and shaky; but they are not accustomed to much colour here, and he will pass well enough."

As soon as Mr. Atherton had taken his seat Mrs. Renshaw and Marion came up to him. "How can we thank you enough, Mr. Atherton, for the risks you have run to succour Wilfrid, and for your kind consideration in going on shore to wait for him?"

"It was nothing, Mrs. Renshaw. I own to enjoying a scrimmage when I can go into one with the feeling of being in the right. You know that I am a very lazy man, but it is just your lazy men who do enjoy exerting themselves occasionally."

"It was grand!" Marion broke in; "and you ought not to talk as if it was nothing, Mr. Atherton. Wilfrid said that he thought it was all over with him till he saw a big man flying down the road."

"A perfect colossus of Rhodes!" Mr. Atherton laughed.

"It is not a thing to joke about," Marion went on earnestly. "It may seem very little to you, Mr. Atherton, but it is everything to us."

"Don't you know that one always jokes when one is serious, Miss Renshaw? You know that in church any little thing that you would scarcely notice at any other time makes you inclined to laugh. Some day in the far distance, when you become a woman, you will know the truth of the saying, that smiles and tears are very close to each other."

"I am getting to be a woman now," Marion said with some dignity; for Mr. Atherton always persisted in treating her as if she were a child, which, as she was nearly seventeen, was a standing grievance to her.

"Age does not make a woman, Miss Renshaw. I saw you skipping three days ago with little Kate Mitford and your brother and young Allen, and you enjoyed it as much as any of them."

"We were trying which could keep up the longest," Marion said; "Wilfrid and I against the other two. You were looking on, and I believe you would have liked to have skipped too."

"I think I should," Mr. Atherton agreed. "You young people do not skip half as well as we used to when I was a boy; and I should have given you a lesson if I had not been afraid of shaking the ship's timbers to pieces."

"How absurd you are, Mr. Atherton!" Marion said pettishly. "Of course you are not thin, but you always talk of yourself as if you were something monstrous."

Mr. Atherton laughed. His diversion had had the desired effect, and had led them away from the subject of the fight on shore.

"There is a galley putting off from shore with a lot of officials on board," the captain said, coming up at this moment. "They are rowing to the next ship, and I suppose they will visit us next."

A quarter of an hour later the galley came alongside, and three officials mounted the gangway. The captain went forward to meet them. "Is there anything I can do for you, gentlemen?"

"There has been a crime committed on shore," the leader of the party said, "and it is suspected that some of those concerned in the matter are on board one of the ships in the harbour. I have authority to make a strict search on board each."

"You are perfectly welcome to do so, sir," the captain said. "One of our officers will show you over the ship."

"I must trouble you to show me your list of passengers and crew, and to muster the men on deck. But first I must ask you, Did any of your boats return on board late?"

"No," the captain replied. "Our last boat was hauled up to the davits at half-past nine. There was a heavy day's work before the men to-day, and I therefore refused leave on shore."

The men were ordered to be mustered, and while they were collecting the second-mate went round the ship with the officials, and they saw that no one was below in his berth. The men's names were called over from the list, and the officials satisfied that all were present and in good health.

"Now for the passengers," he said

"I cannot ask them to muster," the captain observed, "but I will walk round with you and point out those on the list. There are some eight or ten on shore. They will doubtless be off to lunch; and if you leave an officer on board he will see that they are by no means the sort of people to take part in such an affair as that which has happened on shore."

The officials went round the deck, but saw nothing whatever to excite their suspicion. Marion Renshaw was laughing and talking with Mr. Atherton, Miss Mitford walking up and down the poop in conversation with James Allen. After they had finished their investigations, the officials left one of their party to inspect the remaining passengers as they came on board, and to check them off the list. They then again took their seats in the galley and were rowed to the next ship.

By dint of great exertions the cargo was got out by sunset, the sails were at once loosened and the anchor weighed, and before the short twilight had faded away the Flying Scud was making her way with a gentle breeze towards the mouth of the harbour.

"We are well out of that," Mr. Atherton said as he looked back at the lights of the city.

"I think you are very well out of it indeed, in more senses than one," said the surgeon, who was standing next to him; "but you have had a wonderfully close shave of it, Mr. Atherton. Another inch and either of those blows might have been fatal. Besides, had you been detained for a month or six weeks, it is as likely as not that, what with the heat and what with the annoyance, your wound would have taken a bad turn. Now, you must let me exercise my authority and order you to your berth immediately. You ought not to have been out of it. Of the two evils, getting up and detention, I chose the least; but I should be glad now if you would go off at once. If you do not, I can assure you I may have you on my hands all the rest of the voyage."

"I will obey orders, doctor. The more willingly because for the last hour or two my back has been smarting unmercifully. I do not feel the other wound much."

"That is because you have been sitting still. You will find it hurt you when you come to walk. Please go down carefully; a sudden movement might start your wounds again."

It was two or three days before Mr. Atherton again appeared on deck. His left arm was bandaged tightly to his body so as to prevent any movement of the shoulder-blade, and he walked stiffly to the deck-chair, which had been piled with cushions in readiness.

"I am glad to be out again, Mrs. Renshaw," Mr. Atherton said as she arranged the cushions to suit him. "Your husband, with Wilfrid and the two Allens, have kept me company, one or other of them, all the time, so I cannot say I have been dull. But it was much hotter below than it is here. However, I know the doctor was right in keeping me below, for the slightest movement gave me a great deal of pain. However, the wounds are going on nicely, and I hope by the time we get to Buenos Ayres I shall be fit for a trip on shore again."

"I hardly think so, Mr. Atherton; for if the weather continues as it is now – it is a nice steady breeze, and we have been running ever since we left Rio – I think we shall be there long before you are fit to go ashore."

"I do not particularly care about it," Mr. Atherton said. "Buenos Ayres is not like Rio, but is for the most part quite a modern town, and even in situation has little to recommend it. Besides, we shall be so far off that there will be no running backwards and forwards between the ship and the shore as there was at Rio. Of course it depends a good deal on the amount of the water coming down the river, but vessels sometimes have to anchor twelve miles above the town."

"I am sure I have no desire to go ashore," Mrs. Renshaw said, "and after the narrow escape Wilfrid had at Rio I should be glad if he did not set foot there again until we arrive at the end of the voyage."

"He is not likely to get into a scrape again," Mr. Atherton said. "Of course it would have been wiser not to have stopped so late as they did in a town of whose ways they knew nothing; but you may be sure he will be careful another time. Besides, I fancy from what I have heard things are better managed there, and the population are more peaceable and orderly than at Rio. But, indeed, such an adventure as that which befell them might very well have happened to any stranger wandering late at night in the slums of any of our English seaports."

There was a general feeling of disappointment among the passengers when the Flying Scud dropped anchor in the turbid waters of the La Plata. The shore was some five or six miles away, and was low and uninteresting. The towers and spires of the churches of Buenos Ayres were plainly visible, but of the town itself little could be seen. As soon as the anchor was dropped the captain's gig was lowered, and he started for shore to make arrangements for landing the cargo. The next morning a steam tug brought out several flats, and the work of unloading commenced. A few passengers went ashore in the tug, but none of the Renshaws left the ship. Two days sufficed for getting out the goods for Buenos Ayres. The passengers who had been staying at hotels on shore came off with the last tug to the ship. Their stay ashore had been a pleasant one, and they liked the town, which, in point of cleanliness and order, they considered to be in advance of Rio.
