"Dora Stanhope!" ejaculated Tom and Sam in a breath.

Then the girl started and turned her eyes ashore. "Tom Rover! And Sam!
Where in the wide world did you come from?"

The Baxters fell back, almost overcome, and the father clutched the arm of his son savagely.

"We've put our foot into it here," he muttered.

"Who would have supposed that she was on this boat?" came from the son.

"Do you know these folks, Miss Stanhope?" questioned Randy Fairwell.

"Yes, I know all of them." answered the girl, when she had somewhat recovered from her surprise.

"Of course she knows us," put in Tom, "and she knows those rascals, too; don't you, Dora?"

"Yes, Tom. But how did you come here?"

"It's a long tale, Dora. But just now I want you to help me bring the Baxters to justice. They are trying to make out that they are all right and that we are crazy."
