Dora drove around the block twice, and then around two blocks twice. Finally, three blocks away, she found a parking space she hoped she might be able to occupy, but it took ten minutes of sweaty maneuvering to wedge the Escort against the curb. She locked up and walked back to Gregor Pinchik's building in SoHo. She didn't even want to think about the eventual problem of wiggling the Ford out of that cramped space.

The computer maven had the top floor of an ancient commercial building that had recently been renovated. There were new white tiles on the lobby floor, and on the walls were Art Deco lighting fixtures with nymphs cavorting on frosted glass. The original freight elevator-big enough to accommodate a Steinway-had been spruced up with crackled mirrors and framed prints of Man Ray photographs.

Pinchik's loft was illuminated by two giant skylights that revealed a sky as dull as a sidewalk. But there was track lighting to fill the corners, and Brahms played softly from an Aiwa stereo component system that had more knobs, switches, gauges, and controls than a space shuttle.

"How about this, lady?" Gregor cried, waving an arm at his equipment.

He gave Dora what he called the "fifty-cent tour," warning her not to trip on the wires and cables snaking across the floor. He displayed, and occasionally demonstrated, a bewildering hodgepodge of computers, monitors, printers, modems, tapes and disks, telephones, fax and answering machines, digital pagers, hand-held electronic calculators, and much, much more.

"I'm a gadget freak," the bearded man admitted cheerfully. "If it's electronic, I gotta have it. A lot of this stuff is junk, but even junk can be fun. Now you sit down over here, and I'll get you caught up on the adventures of our pigeon."

Dora sat in a comfortable swivel chair, and Pinchik perched on a little steel stool that rolled about on casters. He settled in front of a monitor and punched a few buttons with his stubby fingers.

"I put the whole file on one tape," he said. "You know what I collected in Dallas and Denver. Now we'll get to the new things."

Typed lines began to reel off across the screen, and Pinchik leaned closer to read.

"All right," he said, "here's the scoop I got from my hacker pals in KC. Our hero showed up in Kansas City after leaving Denver. Now he's Turner Pierce. Same initials, but who the hell knows if it's his real name."

"Still got the mustache?" Dora asked.

"Still got it. And he's still on the con. The reason the KC hackers knew so much about him was that he set up what was apparently a legitimate business. Office, secretary, letterheads, advertisements-the whole schmear. He called himself a computer consultant and designer of complete systems for any size business, large or small. He was one of the first in that field in KC, and he made out like gangbust-ers. First of all, he knew his stuff, and he never tried to sell a client more hardware than he needed. Of course Pierce was probably getting a kickback on the equipment he did recommend, but that was small potatoes. He lined up some hefty clients: a bank and its branches, a local college, an insurance company, a chain of retail shoe stores, and a lot of factories, distributors, supermarkets, an entire shopping mall, and so forth."

"So he went legitimate?"

"That's what everyone thought. At first. Then there was a string of computer swindles. The bank took heavy losses in cash, and the shoe stores and distributors lost merchandise delivered and logged in as paid for, though payment was never actually made. And the insurance company found itself paying off claims on policies it had never written."

"Don't tell me, Greg," Dora said. "I can guess."

"You got it," Pinchik said, nodding. "All those victims had computer systems installed by Turner Pierce Associates, Inc. What he was doing was leaving what we call a 'trapdoor' in every system he designed. In its simplest form this would be an access code, maybe just a single word or a six-digit number, that would enable a bandit to get into the system from outside, rummage around in all the records, and clip the business the way he wanted for as much as he wanted."

"And that's what Turner was doing?"

The computer expert shook his shaggy head. "Nope," he said, "he was too smart for that. He followed the same pattern we saw him use in Dallas and Denver. He never did the dirty deed himself, but he sold those trapdoors to guys greedier and dumber than he was. When all those crimes came to light, some of the actual crooks were nabbed and convicted, but Pierce folded his tent and quietly slipped away."

"Greg, some of those guys who were convicted must have tried to plea bargain by giving the prosecutor Turner Pierce's name."

"Sure, they fingered him as the guy who sold them access to the computer systems. But what evidence did the prosecutor have to come down on Pierce? No evidence. Just the accusation of an indicted criminal. There was no case against Pierce that would hold up in court, so he was advised to get out of town."

"And he came to New York."

"That's it," Pinchik agreed, then pressed more buttons on his console. "But I haven't told you the juiciest part yet. Wait a sec." He stood to peer more closely at the screen. "Yeah, here it is. You remember I told you that when Pierce set up his business in Kansas City, he had an office, a secretary, everything seemingly legit."

"I remember."

"The secretary was a tall, luscious lady with the first name of Helene."

"His sister!" Dora cried.

"I guess," Pinchik said. "The description I got matches the one you gave me. And when Turner Pierce lammed out of Kansas City, Helene disappeared at the same time, so I guess she came to New York with him."

"I guess she did," Dora said.

Pinchik sat down again on his little stool and wheeled around to look at her. "But I haven't given you the icing on the cake," he said, his face expressionless. "Before this Helene went to work in Turner Pierce's office, she was a hooker."

Dora stared at him a moment. Then: "You're sure?" she asked huskily.

He nodded. "I got the same data from two different sources, and I think it's for real. She was a hooker all right. But I don't mean she walked the streets or leaned against lampposts. My guys tell me she was more like a call girl, a high-priced call girl. She had some very important men as regular customers, and when a convention came to town, she did okay."

Dora took a deep breath. "Do you mind if I smoke?" she asked.

"Only if you give me one," Pinchik said. "I'm all out."

They lighted up and sat a few moments in silence, staring at the ceiling. "It's a wonderful world," Dora said finally.

"You can say that again," Pinchik said.

"It's a wonderful world," Dora said again, smiling. Then she lowered her gaze to stare at the grizzled man, the gadget freak who could use electronics to strip people naked. "Tell me, Greg: You're a been-around guy, what's your take on Turner Pierce?"

Pinchik regarded the glowing end of his cigarette. "I fell once. I knew it was wrong while I was doing it and, God willing, I'll never fall again. But this Pierce comes across as a natural-born outlaw. He just doesn't give a damn. Look, the guy is smart. When it comes to computers, he may even be close to a wunderkind. If he had gone straight, he might have been a zillionaire by now. But like I said, he just doesn't give a damn. No laws or rules for him. He bulls his way through life, and if someone gets hurt, that's tough shit. Excuse my language, lady."

"I've heard worse."

"Also," Pinchik said, "I think he could be very, very dangerous. Remember that."

"I'll remember," Dora promised.

Pinchik dropped his cigarette butt to the tiled floor and ground it out under his heel. "So now we've got Helene and Turner Pierce in New York. I guess that ends my job-right?"
