"Gaston," I said. "Maybe I can get under it now, and heave from the other side." Gaston moved back, and I let myself down into the reeking water. I worked an arm through, then dropped down waist deep, chest deep, pushing. The rough metal scraped my face, caught at my clothing; but I was through.

I crawled back up, dripping, and rested. From the darkness behind Gaston I heard a meshing of oiled metal parts and then the cavern echoed with the thunder of machine gun fire. In the flashing light I saw Gaston stiffen against the grating and fall. He hung by one hand, caught in the grating. There were shouts, and men dropped onto the stone coping at the culvert mouth. Gaston jerked, fumbled his pistol from his blouse.

"Gaston," I said. "Quick, under the bars...." I was helpless. I knew he was too big.

A man appeared, clinging to the coping with one hand, climbing down to enter the dark opening. He flashed a light at us and Gaston, still dangling by the left hand, fired. The man fell over into the stream with a tremendous splash.

Gaston gasped. "That's ... all...." The gun fell from his hand into the black water.

I moved fast now, from one hand-hold to the next, slipping and clutching, but not quite falling somehow. I managed to get a look back as I reached the open air. Two men were tugging at the body wedged in the opening. Even in death, Gaston guarded my retreat.

I came up over the side, and flattened against the wall, slug-gun in my hand; the street was empty. They must have thought they had us trapped; this side was deserted. I was directly under the tower. I eased out a few feet, and craned my neck; a shadow moved at the top of the tower. There was still one man on duty there. He must have heard the grating fall and called for reinforcements.

I looked down the street ahead. I recognized the Street of the Olive Trees, the same one I had come through on my way out with Gros, ten days earlier. It slanted down, curving to the right. That was where I had to go, into the naked street, under the guns. I liked it here in the shadow of the tower, but I couldn't stay. I leaped forward, running for my life. The searchlight snapped on, swung, found me, burning my leaping shadow against dusty walls and the loose-cobbled street. Instinct told me to leap aside. As I did, the gun clattered and slugs whined off the stones to my left. I was out of the light now, and dashing for the protection of the curving wall ahead. The light was still groping as I rounded the turn. No lights came on above me; I ran in utter silence. The dwellers in these scarred tenements had learned to sit silent behind barred windows when guns talked in the narrow streets.

I passed the spot where Gros had died, dashed on. In the distance a whistle blew again and again. A shot rang out, kicking up dust ahead. I kept going.

I heard running feet behind me now. I scanned the shabby stalls ahead, empty and dark, trying to find the one we had used the day we left the palace, where the old woman huddled over her table of clay ware. It had been tiny, with a ragged gray awning sagging over the front and broken pots scattered before it.
