I leaned weakly against the wall for a moment, wondering if the tip had been on the square, knowing instinctively that it had. I leaped and caught the bottom rung of a fire escape, pulled myself up until I could get a foothold.

Then I went upward as quietly as I could. I found an unlocked window on the third floor, slipped silently through. I held my breath for a moment, wondering if I had been heard. Then, my gun in my hand, I sneaked through the darkness.

I covered the entire floor, shaking a bit in nervousness as a rat scuttled to safety. For seconds, I wondered if I might not be smarter by waiting for reinforcements.

And then my mind was made up for me.

On the floor above there was the sudden sound of voices. I went toward the stairs, climbed them slowly. My mouth was dry, and I could feel cold sweat trickling down my spine.

"Come on, come on," That was Tony's voice. "This place'll be hotter than hell in another five minutes."

I edged further up the steps, crouched with my head just below the landing. I heard steps coming my way and saw the flicker of a light. Then I stood up, lifted my gun.

"Hold it," I said, "It's the law."

There were the sounds of startled gasps behind the flashlight, then a gun barked defiantly. I crouched a bit, blasted lead at shadowy figures. I heard someone scream in agony, then a giant hand lifted me and sent me rolling down the steps.

"Got him!" That was Tony again.
