Turber shouted. He struck with his fist at me and flung himself backward. The woman managed to cling to us both, heedless of our knives. She clung; kicked, bit and tore at us. It took a moment for us to shake her off. But in that moment Turber was near a window. He flung a heavy metal chair at us; and turned and leaped like a misshapen cat through the window. His shouts sounded outside, as he ran, giving the alarm.

We would be trapped here in another moment.

"Alan, come on! Get out of here!"

I was free of the woman. I tore her from Alan. She panted: "You let him alone! You let him alone!"

We turned and ran. Leaped into the darkness of the roof, where a turmoil of the alarm was beginning.

How we ever got back I do not know. Hunted, as two rats would have been hunted in that metal labyrinth by a pack of wolves. But we got through safely; found a broken section of the division fence. Ran northward.

The pursuit behind us presently died away. Then we came upon a city police patrol. They saw our red uniforms and very nearly killed us before we could speak. But we convinced them of our identity.

One said: "The tower came!"

It galvanized us. "The tower?"

"Came, but did not stop. Just a phantom."
