Fede grunted. "You don't think it'll be too obvious?"

Art laughed. "There is no such thing as too obvious in this context, man. These guys, they hate the end user, and for years they've been getting away with it because all their users are already used to being treated like shit at the post office and the tube station. I mean, these people grew up with coin-operated stoves, for chrissakes! They pay television tax! Feed 'em shit and they'll ask you for second helpings. Beg you for 'em! So no, I don't think it'll be too obvious. They'll mock up the whole system and march right into MassPike with it, grinning like idiots. Don't worry about a thing."

"OK, OK. I get it. I won't worry."

Art signalled the counterman for their bill. The counterman waved distractedly in the manner of a harried restaurateur dealing with his regulars, and said something in Korean to the busgirl, who along with the Vietnamese chef and the Congolese sous chef, lent the joint a transworld sensibility that made it a favorite among the painfully global darlings of O'Malley House. The bus-girl found a pad and started totting up numbers, then keyed them into a Point-of-Sale terminal, which juiced Art's comm with an accounting for their lunch. This business with hand-noting everything before entering it into the PoS had driven Art to distraction when he'd first encountered it. He'd assumed that the terminal's UI was such that a computer-illiterate busgirl couldn't reliably key in the data without having it in front of her, and for months he'd cited it in net-bullshit sessions as more evidence of the pervasive user-hostility that characterized the whole damned GMT.

He'd finally tried out his rant on the counterman, one foreigner to another, just a little Briton-bashing session between two refugees from the Colonial Jackboot. To his everlasting surprise, the counterman had vigorously defended the system, saying that he liked the PoS data-entry system just fine, but that the stack of torn-off paper stubs from the busgirl's receipt book was a good visualization tool, letting him eyeball the customer volume from hour to hour by checking the spike beside the till, and the rubberbanded stacks of yellowing paper lining his cellar's shelves gave him a wonderfully physical evidence of the growing success of his little eatery. There was a lesson there, Art knew, though he'd yet to codify it. User mythology was tricky that way.

Every time Art scribbled a tip into his comm and squirted it back at the PoS, he considered this little puzzle, eyes unfocusing for a moment while his vision turned inwards. As his eyes snapped back into focus, he noticed the young lad sitting on the long leg of the ell formed by the counter. He had bully short hair and broad shoulders, and a sneer that didn't quite disappear as he shoveled up the dhal with his biodegradable bamboo disposable spork.

He knew that guy from somewhere. The guy caught him staring and they locked eyes for a moment, and in that instant Art knew who the guy was. It was Tom, whom he had last seen stabbing at him with a tazer clutched in one shaking fist, face twisted in fury. Tom wasn't wearing his killsport armor, just nondescript athletic wear, and he wasn't with Lester and Tony, but it was him. Art watched Tom cock his head to jog his memory, and then saw Tom recognize him. Uh-oh.

"We have to go. Now," he said to Fede, standing and walking away quickly, hand going to his comm. He stopped short of dialing 999, though-he wasn't up for another police-station all-nighter. He got halfway up Piccadilly before looking over his shoulder, and he saw Fede shouldering his way through the lunchtime crowd, looking pissed. A few paces behind him came Tom, face contorted in a sadistic snarl.

Art did a little two-step of indecision, moving towards Fede, then away from him. He met Tom's eyes again, and Tom's ferocious, bared teeth spurred him on. He turned abruptly into the tube station, waved his comm at a turnstile and dove into the thick of the crowd heading down the stairs to the Elephant and Castle platform. His comm rang.

"What is wrong with you, man?" Fede said.

"One of the guys who mugged me," he hissed. "He was sitting right across from us. He's a couple steps behind you. I'm in the tube station. I'll ride a stop and catch a cab back to the office."

"He's behind me? Where?"

Art's comm lit up with a grainy feed from Fede's comm. It jiggled as Fede hustled through the crowd.

"Jesus, Fede, stop! Don't go to the goddamned tube station-he'll follow you here."

"Where do you want me to go? I got to go back to the office."

"Don't go there either. Get a cab and circle the block a couple times. Don't lead him back."

"This is stupid. Why don't I just call the cops?"

"Don't bother. They won't do shit. I've been through this already. I just want to lose that guy and not have him find me again later."

"Christ."

Art squeaked as Tom filled his screen, then passed by, swinging his head from side to side with saurian rage.

"What?" Fede said.

"That was him. He just walked past you. He must not know you're with me. Go back to the office, I'll meet you there."

"That dipshit? Art, he's all of five feet tall!"

"He's a fucking psycho, Fede. Don't screw around with him or he'll give you a Tesla enema."

Fede winced. "I hate tazers."

"The train is pulling in. I'll talk to you later."

"OK, OK."

Art formed up in queue with the rest of the passengers and shuffled through the gas chromatograph, tensing up a little as it sniffed his personal space for black powder residue. Once on board, he tore a sani-wipe from the roll in the ceiling, ignoring the V/DT ad on it, and grabbed the stainless steel rail with it, stamping on the drifts of sani-wipe mulch on the train's floor.

He made a conscious effort to control his breathing, willed his heart to stop pounding. He was still juiced with adrenaline, and his mind raced. He needed to do something constructive with his time, but his mind kept wandering. Finally, he gave in and let it wander.

Something about the counterman, about his slips of paper, about the MassPike. It was knocking around in his brain and he just couldn't figure out how to bring it to the fore. The counterman kept his slips in the basement so that he could sit among them and see how his business had grown, every slip a person served, a ring on the till, money in the bank. Drivers on the MassPike who used traffic jams to download music from nearby cars and then paid to license the songs. Only they didn't. They circumvented the payment system in droves, running bootleg operations out of their cars that put poor old Napster to shame for sheer volume. Some people drove in promiscuous mode, collecting every song in every car on the turnpike, cruising the tunnels that riddled Boston like mobile pirate radio stations, dumping their collections to other drivers when it came time to quit the turnpike and settle up for their music at the toll booth.

It was these war-drivers that MassPike was really worried about. Admittedly, they actually made the system go. Your average fartmobile driver had all of ten songs in his queue, and the short-range, broadband connection you had on MassPike meant that if you were stuck in a jam of these cars, your selection would be severely limited. The war-drivers, though, were mobile jukeboxes. The highway patrol had actually seized cars with over 300,000 tracks on their drives. Without these fat caches on the highway, MassPike would have to spend a fortune on essentially replicating the system with their own mobile libraries.

The war-drivers were the collective memory of the MassPike's music-listeners.
