CHAPTER VII
A Motor Boat Chase

Madge quietly opened the door and moved stealthily toward Mr. Burnett’s cabin. Enid, terrified at the thought of remaining behind, followed.

They stole softly along the deck, every muscle tensed for the unexpected. Madge stepped over a coil of rope in her path and too late turned to warn her chum. Enid failed to see it. She stumbled and fell flat on the deck, letting out a sharp exclamation.

Before she could regain her feet, a figure darted from Mr. Burnett’s cabin. He went over the railing like a flash and was lost to view.

“Oh, we mustn’t let him get away!” Madge cried.

She jerked Enid to her feet and they reached the railing just in time to see a motor boat speed away from the yacht.

“Enid, can you run your father’s motor boat?” she demanded.

“Yes, but——”

“Then come on! Our only chance of tracing your father is to follow this man!”

Rex had filled the tank of the motor boat that afternoon, but it required several minutes before Enid had the engine going. Madge cast off and they moved away from the yacht.
