Their sirens were screaming of course and they had their guns working; it was just as I had planned. We tore down the street like jet racers and the traffic melted away before us. They didn't have time to think and realize that _they_ were making sure the road was clear for my escape. The situation was very humorous and I'm afraid I chuckled out loud as I tooled the truck around the tight corners. Of course the alarm had been turned in and the road blocks must have been forming up ahead--but that half mile went by fast at the speed we were doing. It was a matter of seconds before I saw the alley mouth ahead. I turned the truck into it, at the same time pressing the button on my pocket short wave. Along the entire length of the alley my smoke bombs ignited. They were, of course, home made, as was all my equipment, nevertheless they produced an adequately dense cloud in that narrow alley. I pulled the truck a bit to the right until the fenders scraped the wall and only slightly reduced my speed, this way I could steer by touch. The monocycle drivers of course couldn't do this and had the choice of stopping or rushing headlong into the darkness. I hope they made the right decision and none of them were hurt. The same radio impulse that triggered the bombs was supposed to have opened the rear door of the trailer truck up ahead and dropped the ramp. It had worked fine when I had tested it, I could only hope now that it did the same in practice. I tried to estimate the distance I had gone in the alley by timing my speed, but I was a little off. The front wheels of the truck hit the ramp with a destructive crash and the armored truck bounced rather than rolled into the interior of the larger van. I was jarred around a bit and had just enough sense left to jam on the brakes before I plowed right through into the cab. Smoke from the bombs made a black midnight of everything, that and my shaken-up brains almost ruined the entire operation. Valuable seconds went by while I leaned against the truck wall trying to get oriented. I don't know how long it took, when I finally did stumble back to the rear door I could hear the guards' voices calling back and forth through the smoke. They heard the bent ramp creak as I lifted it so I threw two gas bombs out to quiet them down. The smoke was starting to thin as I climbed up to the cab of the tractor and gunned it into life. A few feet down the alley and I broke through into sunlight. The alley mouth opened out into a main street a few feet ahead and I saw two police cars tear by. When the truck reached the street I stopped and took careful note of all witnesses. None of them showed any interest in the truck or the alley. Apparently all the commotion was still at the other end of the alley. I poured power into the engine and rolled out into the street, away from the store I had just robbed.
