“Shall we go back?”

“Billy is in that ship,” she replied softly. “We cannot leave him. His liberty, and very likely his life, depend upon our actions.”
He put his hand affectionately on her shoulder—just like a chum. Few brothers loved their sisters as Epworth loved Joan.
“You are the bravest, squarest girl in the world. I knew you would say it. But——”
He shook his head.
“We will have to depend upon stealing enough gas from the tank of the Greyhound to get back,” she added smilingly.
Now the Greyhound turned abruptly westward, and followed the Cherski Mountains, lowering its altitude to five hundred feet above the highest peak. Epworth followed persistently, keeping a higher altitude.
