“We must prevent it if we can,” Madge returned quietly. “But just how can it be managed?”

“We might go to the police ourselves with the story.”

“No, that wouldn’t do. Enid would never forgive us. And if harm should befall her father, we’d be largely responsible.”

“Then, I don’t see what we can do. Unless we strand her tomorrow at Bay City! I might pretend the amphibian broke down.”

Madge considered this suggestion a minute before shaking her head.

“I’m afraid that won’t do either. Enid would simply go wild. And such a scheme might ruin all chances of ever finding Mr. Burnett. No, we must think up a better plan. We’ll have another day to consider it.”

“I’d be glad to go to Cedar Point myself if Enid would permit it.”

“We’ll find some way, Rex. But it won’t be easy, for Enid is set upon obeying those kidnappers to the letter. We must protect her against herself.”

The motor boat coasted in to a landing and was made fast. Madge thanked Rex and said goodbye to him at the wharf. From his directions, she easily made her way to the telegraph office.

She sat down at a desk and hastily scribbled a message to her Aunt Maude and Uncle George Brady, assuring them of her safe arrival at Cheltham Bay. She signed her name in full, and as she handed the telegram to the clerk in charge, he looked up in surprise.
