“If what you say is true, young man,” put in the officer, “the anticipated court martial may never convene.”
“We can prove it!” protested Jimmie vigorously.
“Then we have solved the Mystery of the ‘U-13’!” declared the officer, with evident relief.
“And now we’ll head for the little old U.S.A. and peaceful neutrality!” was Jimmie’s joyful comment.
“But you’ll first arrange to care for your share of the cargo aboard my boat,” interposed the injured Mackinder.
He would not entertain any of the objections raised by the boys, but insisted that they share in the treasure which had been recovered from the ocean’s grasp.
A few days later as the boys watched the chalk cliffs of Dover slip away into the eastern horizon Jimmie turned from the rail of the steamer upon which they had taken passage.
“Good by, England, and good by the Mackinders,” he said. “I’m glad we are out of the war zone at last and that we solved the Mystery of the ‘U-13’.”
THE END
