We were at the top. A long line of soldiers curved about the mouth of the pit. The next shift waiting to go down? No—they made no move to approach. And each one was holding his ray-tube at the ready. This was the guard. At a table nearby a knot of officers was gathered. Papers of some sort were piled high on it. Again the icy finger of dread touched me. One of the officers moved aside, revealing the profile of his companion. The Ferret. Then I knew I was done for!

My eyes darted here and there, seeking escape. No hope—the heavily armed guard was all around; the platform blocked the shaft mouth. A dash would be self-betrayal—suicide.


echanically I obeyed the sergeant's barked commands. We were in single file. We were moving toward that ominous table where the Ferret stood, a sardonic smile on his sharp-featured face. I could make out a livid weal across his throat. I had left my mark on him. That was some satisfaction.

The head of the line reached the table. They were fingerprinting the leader! A lieutenant extracted a paper from the pile and handed it to the Ferret. He made momentary comparison of something on the paper with the mark the soldier had just made. Then the next man stepped up, while the first made off across the plain.

Of course! Simple: how very simple! And yet it had caught me! The service records of the men had their fingerprints, just as in our own forces. And each man in the area was being checked up. Trust the Ferret to think of that. He knew that I'd be somewhere in their ranks, impersonating one of their men. Well, I was in for it. The last trick in our long game was his.

My turn. No use going through the motions. I bent down a moment, then straightened. "Oh, hello, Bolton," the Ferret said, thrusting out his hand, the one with the twisted finger. I had resumed my own visage. "Didn't think you could get away with it, did you?"

Chagrined as I was, I put a good face on it. The Ferret and I had run up against each other many many times. Cheerfully, either of us would have cut the other's throat. But—we played the game.

"Hello, Rubinoff," I responded. "You seem to have me, just now. But try and hold me."
