Morton gave the orders for the boats to pull back to the “Scorpion.” It was heavy work, for there was a strong wind and a heavy sea; but the crews encouraging each other cheerfully pulled on.

What joy filled Morton’s heart at having been the means of preserving Edda’s life and that of her father and mother! He did not press her to say much; but a few words explained how they came to be on board the French frigate.

Her feelings were not dissimilar to his. She was with him again, and she had no fear for the future.

Pedro Alvarez, too, was perfectly satisfied with having been taken prisoner, when he found from Colonel Armytage who was his captor. “The very man I wished to meet,” he said to himself. “He will tell me where his father is to be found, and Rolf Morton is an important witness in proving the claim of my poor Hernan. Where can he be though? Probably he had gone with the boats to the assistance of some of the other ships, and was not aware of our danger.”

Just before daylight the boats reached the “Scorpion.” The ladies were carried below to obtain that rest they so much required, and Ronald accommodated the rest of the party as well as he could.

Pedro Alvarez at once went up to him and claimed his acquaintance. “I wish to tell you of circumstances with which it is important you should be acquainted without delay,” he said. “I know that you have every reason to be interested in Donna Hilda Escalante, known as the Lady of Lunnasting.”

Ronald was all attention. He knew how really interested Mrs Armytage was in all concerning her unhappy sister, while he was most anxious to show his gratitude by serving her.

Pedro Alvarez then explained who he himself was, and told his astonished hearer that the pirate Tacon, whom he had on board, was the very man who had carried off Hilda’s child, which child had been rescued and brought up by him.

“Then the young officer whom I have so often and so unexpectedly met, and who appears to have such bitter animosity towards me, is no other than Hernan Escalante, the long-lost son of my kind patroness Donna Hilda?” exclaimed Ronald.

“Such is the case,” said Pedro Alvarez. “He has fallen in love with his fair cousin, and he believes that you are his rival. He has another reason for disliking you, but of that by-and-by. I believe that I can do you a service, and certainly you can do me a considerable one. You owe me a good turn, let me tell you; for in consequence of having assisted you to escape, I was obliged to take command of a privateer, bound for the East Indies, and to make my escape from France. I was wandering about in those seas for many years; but at length, having some friends in power, I was reinstated in the French navy. However, my heart has never been estranged from Spain. She is at peace with England; and as I now hope to see the great object of my existence accomplished—the son of my old captain established in his rights—I purpose throwing off my allegiance to France, and becoming once more a Spaniard. I have told you all this, at a moment so unfitting, because I am anxious that you should endeavour to prevent any of the persons who were on board my frigate from escaping. Tacon will certainly make the attempt. He does not know of what crimes he may be found guilty, and instinctively will do what he can to be at liberty.”
