"But I prefer to call SSD a knowledge service provider--a KSP. Like an Internet service provider."
Sachs had a strange sensation; he seemed almost hurt by what she'd said. She wanted to tell him she wouldn't do it again.
Sterling smoothed a stack of papers on his organized desktop. At first s
he thought they were blank but then she noticed they were all turned facedown. "Well, believe me, if anyone at SSD is involved, I want to find out as much as you do. This could look very bad for us--knowledge service providers haven't been doing very well in the press or in Congress lately."
"First of all," Sachs said, "the killer would have bought most of the items with cash, we're pretty sure."
Sterling nodded. "He wouldn't want to leave any trace of himself."
"Right. But the shoes he bought mail order or online. Would you have a list of people who bought these shoes in these sizes in the New York area?" She handed him a list of the Altons, the Bass and the Sure-Tracks. "The same man would have bought all of them."
"What time period?"
"Three months."
Sterling made a phone call. He had a brief conversation and no more than sixty seconds later he was looking at his computer screen. He swiveled it so Sachs could see, though she wasn't sure what she was looking at--strings of product information and codes.
The CEO shook his head. "Roughly eight hundred Altons sold, twelve hundred Bass, two hundred Sure-Tracks. But no one person bought all three. Or even two pairs."
Rhyme had suspected that the killer, if he used information from SSD, would cover his tracks but they'd hoped this lead would pay off. Staring at the numbers, she wondered if the killer had used the identity-theft techniques he'd perfected on Robert Jorgensen to order the shoes.
"Sorry."
She nodded.
Sterling uncapped a battered silver pen and pulled a notepad toward him. In precise script he wrote several notes Sachs couldn't read, stared at it, nodded to himself. "You're thinking, I'd imagine, that the problem is an intruder, an employee, one of our customers or a hacker, right?"
Ron Pulaski glanced at Sachs and said, "Exactly."
"All right. Let's get to the bottom of it." He checked his Seiko watch. "I want some other people in here. It may take a few minutes. We have our Spirit Circles every Monday around this time."
"Spirit Circles?" Pulaski asked.
"Inspirational team meetings by the group leaders. They should be finished soon. We start at eight on the dot. But some go a little longer than others. Depending on the leader." He said, "Command, intercom, Martin."
Sachs laughed to herself. He was using the same sort of voice-recognition system that Lincoln Rhyme had.
"Yes, Andrew?" The voice came from a tiny box on the desk.
"I want Tom--security Tom--and Sam. Are they in Spirit Circles?"
"No, Andrew, but Sam's probably going to be in Washington all week. He won't be back till Friday. Mark, his assistant's in."
"Him, then."
"Yes, sir."
"Command, intercom, disconnect." To Sachs he said, "Should just be a moment."
She imagined that when Andrew Sterling summoned you, you materialized pretty quickly. He jotted a few more notes. As he did, she glanced at the company logo on the wall. When he was through writing she said, "I'm curious about that. The tower and the window. What's the significance of it?"
"On one level it just means observing data. But there's a second meaning." He smiled, pleased to be explaining this. "Do you know the concept of the broken window in social philosophy?"
"No."
"I learned about it years ago and never forgot it. The thrust is that in order to improve society you should concentrate on the small things. If you control those--or fix them--then the bigger changes will follow. Take housing projects with a high-crime problem. You can sink millions into increased police patrols and security cameras but if the projects still look dilapidated and dangerous, they'll stay dilapidated and dangerous. Instead of millions of dollars, put thousands into fixing the windows, painting, cleaning the halls. It may seem cosmetic but people will notice. They'll take pride in where they live. They'll start to report people who are threats and who don't look after their property.
