Suddenly, the figure of a man described a wide arc as it flew out of the supply room and landed with a heavy crash on the floor. Instantly, Torlos leaped at him. There was a trickle of blood from his left shoulder, but he gripped the man in his giant arms, pinning him to the floor. The struggle was brief. Torlos simply squeezed the man's chest in his arms. There was the faint creak of metal, and the man's chest began to bend! In a moment, he was unconscious.

Torlos pulled a heavy leather belt off of the unconscious man and tied his arms with it, wrapping it many times around the wrists, and was picking the man up when Tharlano arrived, followed by Arcot and Morey. Torlos smiled broadly.

"This is one Satorian spy that won't report. I could have finished him when I got my hold on him, but I wanted to take him before the Council for questioning. He'll be all right; I just dented his chest a little."

"We owe our lives to you again, Torlos," Arcot told him gravely. "But you certainly risked your life; the bullet might well have penetrated your heart instead of striking a rib, as it seems to have done."

"Rib? What is a rib?" The thought concept seemed totally unfamiliar to Torlos.

Arcot looked at him oddly, then reached out and ran an exploratory hand over Torlos' chest. It was smooth and solid!

"Morey!" Arcot exclaimed. "These men have no ribs! Their chest is as solid as their skulls!"

"Then how do they breathe?" Morey asked.

"How do you breathe? I mean most of the time. You use your diaphragm and your abdominal muscles. These people do, too!"

Morey grinned. "No wonder Torlos jumped in front of that bullet! He didn't have as much to fear as we do—he had a built-in bullet proof vest! You'd have to shoot him in the abdomen to reach any vital organ."
