Footsteps sounded out at the tunnel end. So soon! I gripped my rock tightly, and waited.

But—it sounded like only one man. I drew myself together. Maybe I had a chance. A dim glow showed where the passage curved, then a disk of light flashed on the wall and flitted about. The fool!

The steps came on, slowly, stumblingly. The disk of light grew smaller as its source drew nearer. Then he was around the corner, bulked for a moment against his own light as it was reflected from the wet wall. That moment was enough! The stone left my hand with all the force I possessed. It went straight to its mark: a sickening thud told me that. The form dropped, and the flashlight clinked on the rocks.

I listened. Still the shouts from without, but no steps inside. I was safe for a time. But the searcher would surely be missed, and others would come looking for him. I had only one chance. I shrugged my shoulders. I couldn't lose anything. If I stayed here my goose was cooked.

By the light of the flashlight I examined my quarry. A renegade Frenchman, apparently. A private. In a trice I had his uniform on me and had twisted my features to match his. Little did I think when I acted under the Klieg lights that the fate of two continents would some day depend on this gift of mine.

He stirred; groaned. I hesitated. Then—well, I couldn't chance his crawling out. His ray-tube was newly charged. I left a heap of ashes there as I walked away....


was outside the cave. I darted a glance around. My refuge was not the only hole in sheer rock; it was literally honeycombed. From one, then another of the cavern mouths a soldier emerged. Each strode across the uneven, rocky plain to where an officer stood with what was apparently a map in his hand. As each searcher saluted and reported, the officer made a mark on the map. Someone came out from the cave-mouth next to mine. I fell in behind him.

"No one in cave twenty-one, sir."
