Suddenly the door to the bedroom opened and young Billy burst into the room, clad only in his pajamas.

"Don't sign, Pa!" he screamed. "Wait and tell Captain Strong first!"

"Strong!" exclaimed Vidac. "Has he been here?"

Logan nodded his head, and taking Vidac's pen, started to sign the paper.

"No—no, don't, Pa!" cried Billy. "Don't—!"

Logan paid no attention and finished signing. A look of deep hurt filled the boy's eyes. "A—a spaceman—" he stammered, "a Solar Guardsman would never have given up!" Crying, he turned away and buried his head in his sister's arms. Logan silently gave Vidac the paper and turned away.

"Thank you, Mr. Logan," said Vidac with a smile. "That's all. Good night!" He turned and motioned for Winters to follow him. "Come on. Let's get back to the city!"

Billy, Jane, and their father silently watched the two men leave the house. Even as the roar of the super-charged jet car faded away in the distance, they still stood in silence.

Finally Logan turned to his son and daughter. "There ain't but one thing left to do. Go back to Venus as soon as we can get passage. I'm sorry, Billy, but—"

"That's all right, Pa," said Billy. "I guess I would have done the same thing—for Jane."
