“Goodbye, Frank,” he said softly. “Remember that I am glad to do this for you. I have no one in the world, while you still have a father and friends at home. Take my advice and return to your own country. Our war is none of your quarrel.”

Tears came into Frank’s eyes as he gripped his chum’s hand. A lump came into his throat.

“Goodbye, Jack,” he said with an effort.

He staggered toward the tube, and Lord Hastings helped him in. “Get it over quickly,” he exclaimed.

“Ready?” asked Jack.

“Ready,” replied Frank in a choking voice.

“Click!”

Frank went hurtling on his way to safety.

Jack turned to Lord Hastings.

“I am glad you stayed until last,” he said very quietly. “I feared that Frank would make a scene. Thank you.”
