Patrick O'Donoghan, as far as Erik could make out through Mr. Bowles' rambling account of him, was not a model of virtue. The proprietor of the Red Anchor had known him as a cabin-boy and sailor, both before and after the loss of the "Cynthia." Up to that time Patrick O'Donoghan had been poor, as all sailors are. After the shipwreck he had returned from Europe with a large bundle of bank-notes, pretending to have inherited some money in Ireland, which seemed likely enough.

Mr. Bowles, however, had never believed in this inheritance. He thought that this sudden accession of wealth was connected in some way with the loss of the "Cynthia," and that Patrick O'Donoghan was afraid to say so; for it was evident that contrary to the usual habit of seamen in such cases, he carefully avoided speaking about the sad occurrence. He would always turn the conversation if any one alluded to it before him, and he was very anxious to start on a long voyage before the lawsuit brought by the company to recover the insurance due on the "Cynthia" should take place. He did not wish to be summoned as a witness. This conduct appeared very suspicious, as he was the sole known survivor from the shipwreck. Mr. Bowles and his wife had always suspected him, but they had kept their own counsel.

What looked still more suspicious was the fact that when Patrick O'Donoghan was in New York he was never short of money. He brought back very little with him after a voyage, but a few days after his return he always had gold and bank-notes; and when he was tipsy, which frequently happened, he would boast of being in possession of a secret which was worth a fortune to him. The words which most frequently escaped from his lips were, "the baby tied to the buoy!"

"The baby tied to the buoy," he would say, striking the table with his fist, "The baby tied to the buoy is worth its weight in gold."

Then he would laugh, as if well satisfied with himself. But they could never draw out of him any explanation of these words, and for many years the Bowles household were lost in conjectures as to what they could possibly mean.

This accounted for Mrs. Bowles' excitement, when Erik suddenly announced to her that he was the famous baby who had been tied to a buoy.

Patrick O'Donoghan, who had been in the habit of lodging at the Red Anchor, whenever he was in New York, for more than fifteen years, had not been seen there now for more than four years. There had also been something mysterious about his last departure. He had received a visit from a man who had been closeted with him for more than an hour. After this visit Patrick O'Donoghan, who had seemed worried and troubled, had paid his board bill, taken his carpet bag, and left in a hurry.

They had never seen him since that day.

Mr. and Mrs. Bowles were naturally ignorant of the cause of his sudden departure, but they had always thought that it had some connection with the loss of the "Cynthia." In their opinion the visitor had come to warn Patrick O'Donoghan of some danger which threatened him, and the Irishman had thought it prudent to leave New York immediately. Mrs. Bowles did not think he had ever returned. If he had done so, they would have been sure to hear of him through other seamen who frequented their house, and who would have been astonished if Patrick O'Donoghan had boarded anywhere else, and would have been sure to ask questions as to the reasons for his doing so.

This was the substance of the story related to Erik, and he hastened to communicate it to his friends.

His report was naturally received with all the interest which it merited. For the first time, after so many years, they were on the track of a man who had made reiterated allusions to the baby tied to a buoy. It was true they did not know where this man was, but they hoped to find him some day. It was the most important piece of news which they had as yet obtained. They resolved to telegraph to Mrs. Bowles, and beg her to prepare a dinner for six persons. Mr. Bredejord had suggested this idea, as a good means of drawing the worthy couple out; for while they talked during the dinner, they might be able to glean some new facts.

Erik had little hopes of obtaining any further information. He thought that he already knew Mr. and Mrs. Bowles well enough to be convinced that they had told him all that they knew. But he did not take into account Mr. Bredejord's skill in questioning witnesses, and in drawing from them information which they themselves were scarcely aware of.

Mrs. Bowles had surpassed herself in preparing the dinner. She had laid the table in the best room on the first floor. She felt very much flattered at being invited to partake of it, in the society of such distinguished guests, and answered willingly all of Mr. Bredejord's questions.

They gathered from this conversation a certain number of facts which were not unimportant.

One was that Patrick O'Donoghan had said at the time, of the lawsuit against the insurance company, that he was going away to avoid being summoned as a witness. This was evident proof that he did not wish to explain the circumstances under which the shipwreck had occurred, and his subsequent conduct confirmed this theory. It was also evident that in New York or its environs he received the suspicious revenue which seemed to be connected with his secret. For when he arrived he was always without money, but after he had been about for a short time he always returned with his pockets full of gold. They could not doubt that his secret was connected with the infant tied to the buoy, for he had frequently affirmed that such was the case.

The evening before his sudden departure Patrick O'Donoghan had said that he was tired of a sea-faring life, and that he thought he should give up making voyages, and settle in New York for the remainder of his life.

Lastly, the individual who had called to see Patrick O'Donoghan was interested in his departure, for he had called the next day and asked for the Irishman who was boarding at the Red Anchor, and had seemed pleased to hear that he was no longer there. Mr. Bowles felt sure that he would recognize this man if he saw him again. By his conversation and actions he had believed him to be a detective, or some agent of the police.

Mr. Bredejord concluded from these facts that Patrick O'Donoghan had been systematically frightened by the person from whom he drew the money, and that this man had been sent to make him fear that criminal proceedings were about to be taken against him. This would explain his precipitate flight, and why he had never returned to New York.

It was important to find this detective, as well as Patrick O'Donoghan.

Mr. and Mrs. Bowles, by referring to their books, were able to give the exact date of the Irishman's departure, which was four years, lacking three months; although they had previously believed that it was four or five years ago.

Dr. Schwaryencrona was immediately struck by the fact that the date of his departure, and consequently of the visit of the detective, corresponded precisely with the date of the first advertisements which he had caused to be made in Great Britain for the survivors of the "Cynthia." This coincidence was so striking that it was impossible not to believe that there was some connection between them.

They began to understand the mystery a little better. The abandonment of Erik on the buoy had been the result of some crime--a crime of which the cabin-boy O'Donoghan had been a witness or an accomplice. He knew the authors of this crime, who lived in New York or its environs, and he had for a long time enjoyed the reward of his secrecy. Then a day had come when the excessive demands of the Irishman had become burdensome, and the announcement in the newspapers by advertisement had been made use of to frighten Patrick, and cause his hurried departure.

In any case, even if these deductions were not correct in every point, they had obtained sufficient information to entitle them to demand a judicial investigation.

Erik and his friends therefore left the Red Anchor full of hope that they would soon obtain some favorable intelligence.

The next day Mr. Bredejord was introduced by the Swedish consul to the chi............
