“But it won’t,” says Mr. Browning.

I looked at Catty and Catty looked at me. That was funny kind of talk, and I wondered what we were getting into.

We turned up the sound, and, sure enough, the black yacht circled and turned and came right along in our wake, about half a mile behind us. Topper pointed. “There,” says he, “what did I tell you?”

“You’re seeing things,” says Mr. Browning. “Black boat, isn’t there?”

“Yes.”

“Turned and followed us, didn’t she?”

“She turned, but not to follow us. Why, Topper, what in the world would anybody follow us for?”

“You know that as well as I do,” said Mr. Topper.

“But nobody knows but you and I.”

“Can’t ever tell. You can’t keep anything secret in this world.”
