Neither girl replied.

Jones motioned toward the launch.

“Climb aboard, there, quick!” he commanded.

Both girls hesitated.

“You hear me?” demanded Jones, taking a step forward. “I am not to be trifled with. Move now!”

Shirley and Mabel thought better of their hesitancy, and without a word climbed aboard the Sybil. Jimmy was shoved aboard after them, and then came Jones. Briggs stopped to shove the boat off and then clambered aboard.

“Straight down the creek,” ordered Jones, as Briggs stooped over the engine.

The launch moved off slowly.

“You see we gave your friends the slip,” smiled Jones. “Now we’ll just leave them behind.”

“What are you going to do with us?” demanded Shirley.
