"Walk!" stormed Phelps angrily. "You can't cover that stairway in the elevator, you fumbling idiot."

"But, sir—"

"Someone could easily come down while you go up."

"I know that, sir, but—"

"Then why do you disobey?" roared Phelps.

"Well, you see, sir, I know how this place is built and no one has ever made it yet. Who could?" The guard looked mystified.

Phelps had to face that fact. He did not accept it gracefully. "My orders are orders," he said stiffly. "You'll follow them. To the last letter."

"Yes sir. I will."

"See that you do. Now, I'm going up. I'll ride and you walk. Meet me on the fourth and bring the elevator down with you."

"Yessir."
