“Oh, please let me go!” cried Mrs. Stanhope, almost tearfully. “Mr. Crabtree, I do not want to go with you another step! Please let me go!”

“Keep quiet, Mrs. Stanhope, don’t excite yourself,” he answered, trying to soothe her. But he was so nervous his voice trembled as he spoke. He had not dreamed that the pursuit would become so swift and sure.

Closer and closer drew the steam tug, until those on board could plainly see all that was taking place on the motor boat.

“I command you to stop!” yelled Captain Wells. “Stop, or we’ll run you down.”

“No, no, don’t you do that!” screamed Josiah Crabtree, in fright.

“Save me! Oh, save me!” screamed Mrs. Stanhope, and then, of a sudden, she sprang to her feet, leaped to the stern deck of the motor boat, and cast herself headlong into the waters of the bay.

The movement was so unexpected by the others on the Magnet that not a hand was raised to detain her. She went down, directly in the path of the oncoming tug.

“Stop! Back her!” screamed Dick, in horror, and Tom and Sam also yelled out a warning. There was a quick jangling of a bell, and the engine was stopped. Then the power was reversed, and the steam tug was steered to one side.

“There she is!” cried Tom, pointing with his hand, and the next instant came a splash, as Dick made a dive overboard. He, too, had seen Mrs. Stanhope floating near, and soon he had her in his arms and was supporting her.
