"Why?" asked Mr. Robinson, truculently. "Do you mean we cannot see the prisoner, or that you will not release him?"

"Both!" was the surprising answer. "You cannot see Senor Ralcanto because he is not here. And I cannot release him, had I the power, for he has released himself. In other words, Senor, he has escaped!"

"Escaped!" cried Jack and Cora in a breath. "My father escaped!" murmured Inez. "Oh, praise ze dear God for zat! He is free! Oh, but where is he?"

"That I know not, Senorita," was the stiff answer. "I wish I did. We have searched for him, but have not found him. He must have had friends working for him on the outside," and he glanced with suspicious eyes at our friends.

"Well, we probably would have worked for him, had we had the chance," said Mr. Robinson, "but we had no hand in his escape. May I ask how he got away from your prison?"

"In a boat—about a week ago," was the grudging reply. "That is all I can say. He is no longer on Sea Horse Island. I have the honor to bid you good-day!"

"Polite, at any rate," murmured Jack. "Bow, what's our next move?"

"To find her father!" exclaimed the British officer, promptly. He had entered into this as enthusiastically as he had into the task of finding the mutineers and smugglers.

"If he got away in a boat," resumed the lieutenant, "he would most likely make for some island. There are many such not far from here, but these Spaniards are so back-numbered, they wouldn't think of making a systematic search. That's for us to do."

"Oh, if we can only find him!" murmured Inez.
