I looked over my shoulder, and didn't like what I saw, and scuttled up that chain of enormous buckets like a roach on a washboard, one hand for me and one hand for Arthur. * * * * * Thank heaven, I had a good lead on my pursuers--I needed it. I was on the bucket chain while they were still almost a city block behind me, along the galleries. I was halfway across the roadway, afraid to look down, before they reached the butt end of the chain. Clash-clatter. _Clank!_ The bucket under me jerked and clattered and nearly threw me into the street. One of those jokers had turned on the conveyor! It was a good trick, all right, but not quite in time. I made a flying jump and I was on the tower. I didn't stop to thumb my nose at them, but I thought of it. I was down those steel steps, breathing like a spouting whale, in a minute flat, and jumping out across the concrete, coal-smeared yard toward the moored launches. Quickly enough, I guess, but with nothing at all to spare, because although I hadn't seen anyone there, there was a guard. He popped out of a doorway, blinking foolishly; and overhead the guards at the conveyor belt were screaming at him. It took him a second to figure out what was going on, and by that time I was in a launch, cast off the rope, kicked it free, and fumbled for the starting button. It took me several seconds to realize that a rope was required, that in fact there was no button; and by then I was floating yards away, but the pudgy pop-eyed guard was also in a launch, and he didn't have to fumble. He knew. He got his motor started a fraction of a second before me, and there he was, coming at me, set to ram. Or so it looked. I wrenched at the wheel and brought the boat hard over; but he swerved too, at the last moment, and brought up something that looked a little like a spear and a little like a sickle and turned out to be a boathook. I ducked, just in time. It sizzled over my head as he swung and crashed against the windshield. Hunks of safety glass splashed out over the forward deck, but better that than my head. Boathooks, hey? I had a boathook too! If he didn't have another weapon, I was perfectly willing to play; I'd been sitting and taking it long enough and I was very much attracted by the idea of fighting back. The guard recovered his balance, swore at me, fought the wheel around and came back. We both curved out toward the center of the East River in intersecting arcs. We closed. He swung first. I ducked-- And from a crouch, while he was off balance, I caught him in the shoulder with the hook. He made a mighty splash. I throttled down the motor long enough to see that he was still conscious. "_Touche_, buster," I said, and set course for the return trip down around the foot of Manhattan, back toward the _Queen_. * * * * *
