me, for the first time looking really scared. "You're insane," he shouted. "I've told you we're in the midst of the Blight." I was keeping one eye on the man up front, who was looking over his shoulder while frantically doing something with his other hand. "You're leaking all over that nice rug," I said. "I'm going to kill you with the next one. Stop this machine." Winter was pale; he swallowed convulsively. "I swear, Mr. Bayard, that's utterly impossible. I'd rather you shoot me. You have no conception of what you're suggesting." I saw now that I was in the hands of a dangerous lunatic. I believed Winter when he said he'd rather die than stop this bus—or whatever it was. In spite of my threat, I couldn't shoot him in cold blood. I turned and took three steps up the passage and poked the automatic into the small of the back that showed there. "Cut the switch," I said.

Winter half crouched in the doorway, face white. "Are we all right, Doyle?" he called in a strained voice. Doyle eased away from the panel, turned his back to me, and glanced over the instruments. He flipped a toggle, cursed, and turned back to face Winter. "Communicator dead," he said. "But we're still in operation." I hesitated now. These two were genuinely terrified of the idea of stopping; they had paid as little attention to me and my noisy gun as one would to a kid with a water pistol. Compared to stopping, a bullet was apparently a trifling irritation. It was also obvious that this was no moving van. The pilot's compartment had more instruments than an airliner, and no windows. Elaborate ideas began to run through my mind. Space ship? Time machine? What the devil had I gotten into? "All right,
