"Oh! If I would only get strong enough go with you!" he exclaimed regretfully.
"Don't worry, you will be strong soon," said Mrs. Racer kindly.
"It was rather mean of us to go away and leave you all alone, momsey," spoke Frank. "And Paul, too. But when Bob called us we just couldn't resist."
"I'll forgive you," said the mother. "I won my golf match after all, and perhaps if you had followed me over the links I might not have done so."
"And I didn't mind being left alone," added Paul. "I'm so glad you got the whale."
"And we may get your motor boat, and find out who that strange man is," said Frank.
"Now go slowly," advised Mr. Racer. "I don't want you boys getting into trouble and danger. I think I had better attend to this matter myself, only I can't very well stay away from the office to-morrow."
"Oh, we can do the work all right," declared Frank. "We'll go in our sailboat, it won't take us long. Perhaps Paul will be strong enough to come along."
"I wish I was," and the invalid shook his head. "But somehow I don't feel so well to-night."
"Then we must have Dr. Martin look at you," decided Mr. Racer, and, in spite of Paul's protests the physician was summoned by telephone.
