"Got it," he said. He set it down. "I don't expect I'm going to be doing many more of these projects after next week. This kind of design, we could never mass-produce it." He looked a little wistful, and Suzanne suppressed a smile. What a tortured artiste this Florida junkyard engineer was! As the long day drew to a close, they went out for a walk in the twilight's cool in the yard. The sopping humidity of the day settled around them as the sun set in a long summer blaze that turned the dry fountain full of Christmas ornaments into a luminescent bowl of jewels. "I got some real progress today," Lester said. He had a cane with him and he was limping heavily. "Got the printer to output complete mechanical logical gates, all in one piece, Almost no assembly, just daisy-chain them on a board. And I've been working on a standard snap-on system for lego-bricking each gate to the next. It's going to make it a lot easier to ramp up production." "Yeah?" Perry said. He asked a technical question about the printer, something about the goop's tensile strength that Suzanne couldn't follow. They went at it, hammer and tongs, talking through the abstruse details faster than she could follow, walking more and more quickly past the vast heaps of dead technology and half-built mall stores. She let them get ahead of her and stopped to gather her thoughts. She turned around to take it all in and that's when she caught sight of the kids sneaking into Perry and Lester's lab. "Hey!" she shouted, in her loudest Detroit voice. "What are you doing there?" There were three of them, in Miami Dolphins jerseys and shiny bald-shaved heads and little shorts, the latest inexplicable rapper style which made them look more like drag queens in mufti than tough-guys. They rounded on her. They were heavyset and their eyebrows were bleached blond. They had been sneaking into the lab's side-door, looking about as inconspicuous as a trio of nuns. "Get lost!" she shouted. "Get out of here! Perry, Lester!" They were coming closer now. They didn't move so well, puffing in the heat, but they clearly had mayhem on their minds. She reached into her purse for her pepper spray and held it before her dramatically, but they didn't stop coming. Suddenly, the air was rent by the loudest sound she'd ever heard, like she'd put her head inside a foghorn. She flinched and misted a cloud of aerosol capsicum ahead of her. She had the presence of mind to step back quickly, before catching a blowback, but she wasn't quick enough, for her eyes and nose started to burn and water. The sound wouldn't stop, it just kept going on, a sound like her head was too small to contain her brain, a sound that made her teeth ache. The three kids had stopped and staggered off. "You OK?" The voice sounded like it was coming from far, far away, though Lester was right in front of her. She found that she'd dropped to her knees in the teeth of that astonishing noise.
