What do you know? he asked the document silently. What aren't you telling us? What secrets are you keeping? What-?

"I've got something," the voice called from the doorway.

They all turned.

Detective Len Hardy trotted into the lab, a sheaf of papers under his arm. He'd been running and he paused, caught his breath. "Okay, Margaret, you were right. I don't shoot and I don't investigate. But nobody's a better researcher than I am. So I decided why don't I do that? I've found out some things about the name. The Digger." He dropped the papers on the desk and started through them. He glanced at the team. "I'm sorry about before. With the mayor. I screwed up. I just wanted to do something to keep people from getting hurt."

"It's all right, Len," Lukas said. "What do you have?"

Hardy asked Dr. Evans, "When you were checking out the name, what databases did you use?"

"Well, the standard ones," the doctor answered. He seemed defensive.

"Criminal?" Hardy asked, "VICAP, N.Y.P.D. Violent Felons, John Jay?"

"Those, sure," Evans said, eyes avoiding Hardy's.

"That was fine," Hardy said, "but I got to thinking why not try noncriminal resources? I finally found it. The database at the Religious History Department at Cambridge University." Hardy opened a notebook. There were dozens of pages inside, indexed and organized. The young detective was right; he sure knew how to research.

"That group you mentioned in San Francisco in the sixties?" he asked Dr. Evans. "The one called the Diggers?"

"But I checked them out," the doctor said. "They were just an acting troupe."

"No, they weren't," Hardy responded. "It was a radical underground political and social movement, centered in Haight-Ashbury. I checked out their philosophy and history, and it turns out they took their name from a group in England in the seventeenth century. And they were a lot more radical. They advocated abolishing private ownership of land. Here's what's significant. They were mostly economic and social but they allied themselves with another group, which was political and more active-sometimes militant. They were called the 'True Levelers.'"

"'Levelers,"' Cage muttered. "That's a damn spooky name too."

Hardy continued. "They objected to control of the people by an upper-class elite and by a central government."

"But what does it mean for us?" Lukas asked.

Hardy said, "It might help us find the last target. What would he want to hit to quote level our capitalistic society?"

Parker said, "Before we can answer that we need to know why he's got it in for society."

"Religious nut?" Geller said. "Remember the crucifix?"

"Could be," Evans said. "But most religious zealots wouldn't want money; they'd want a half hour on CNN."

"Maybe he had a grudge," Parker said.

"Sure. Revenge." Lukas said this.

"Somebody hurt him," Parker said. "And he wants to get even."

Evans nodded. "It's making sense."

"But who? Who hurt him?" Hardy mused, staring again at the ghostly extortion note.

"He got fired?" Cage suggested. "Disgruntled worker."

"No," Evans said, "a psychotic might kill for that but he wasn't psychotic. He was too smart and controlled."

Geller rasped, "Big business, big corporations, fat cats…"

"Wait," Hardy said, "if those were his targets wouldn't he be in New York, not Washington?"

"He was," Cage pointed out. "White Plains."

But Hardy shook his head. "No, remember-White Plains, Boston, Philly? Those were just trial runs for him. This is his grand finale."

"Government," Parker said. "That's why he's here."

Hardy nodded. "And the Diggers objected to central government. So maybe it isn't upper-class society at all." He glanced at Evans. "But the federal government."

Lukas said, "That's it. It's got to be."

Parker: "The government was responsible for something that hurt him." Looking over the team. "Any thoughts on what?"

"Ideology?" Cage wondered aloud. "He's a communist or part of a right-wing militia cell."

Evans shook his head. "No, he would've delivered a manifesto by now. It's more personal than that."

Lukas and Hardy caught each others eyes. It seemed to Parker that they came up with an identical thought at the same time. It was the detective who said, "The death of somebody he loved."

Lukas nodded.

"Could be," the psychologist offered.

"Okay," Cage said. "What could the scenario've been? Who died? Why?"

"Execution?" Hardy suggested.

Cage shook his head. "Hardly ever see federal capital crimes. They're mostly state."

"Coast guard rescue goes bad," Geller suggested.

"Far-fetched," Lukas said.

Hardy tried again, "Government car or truck involved in a crash, postal worker shooting spree, Park Service accident… diplomats…"

"Military," Cage suggested. "Most deaths involving the federal government are probably military related."

"But," Lukas said, "there must be hundreds of fatalities every year in the armed forces. Was it an accident? A training exercise? Combat?"

"Desert Storm?" Cage suggested.

"How old was the unsub?" Parker asked.

Lukas grabbed the medical examiner's preliminary report. She read, looked up. "Mid-forties."

Black…

Then Parker understood. He said, "The black wall!"

Lukas nodded. "The Vietnam Memorial."

"Someone he knew," Hardy said, "was killed in 'Nam. Brother, sister. Maybe his wife was a nurse."

Cage said, "But that was thirty years ago. Could something like this resurface now?"

"Oh, sure," Evans said. "If your unsub didn't work through his anger in therapy it's been festering. And New Year's Eve's a time for resolutions and people taking bold action-even destructive action. There'll be more suicides tonight than on any other night of the year."

"Oh, Jesus," Lukas said.

"What?"

"I just realized-the Memorial's on the Mall. There're going to be two hundred thousand people there. For the fireworks. We've got to close off that part of the park."

"It's already packed," Parker said. "They've been camping out for hours."

"But, Jesus," Cage said, "we need more manpower." He called Artie, the building's night entrance guard, who made an announcement over the PA that all available agents in the building were needed in the lobby for an emergency assignment.

Lukas called Jerry Baker and told him to get his tactical agents to the northwest portion of the Mall. She then paged the deputy director on call for the evening. He called back immediately. She spoke to him for a moment then hung up.

She looked at the team. "The dep director's on his way over. I'm going to meet him downstairs to brief him then I'll meet you at the Memorial."

Cage put his coat on. Geller stood and checked his weapon. It looked alien in his hands, which were undoubtedly much more accustomed to holding a computer mouse.

Lukas said, "Hold on, Tobe. You're going home."

"I can-"

"That's an order. You've already done enough."

He protested a bit more. But in the end Lukas won-though only after promising that she'd call him if she needed any other tech assistance. "I'll have my laptop with me," he said, as if he couldn't imagine ever being more than three feet from a computer.

Lukas walked over to Hardy. "Thanks, Detective. That was damn good police work."

He grinned. "Sony I fucked up with the mayor. He-"

She waved her hand, acknowledging the apology. Offered a slight smile. "Everything's right as rain." Then she asked him, "You still want a piece of the action tonight?"

"Oh, you bet I do."

"Okay, but keep to the rear. Tell me true… You really know how to shoot?"

"I sure as hell do. And I'm pretty good too… if it's not windy." The young detective, still grinning, pulled on his trench coat.

Parker, feeling the weight of the gun in the pocket, donned his jacket. Lukas glanced at him dubiously. "I'm going," he said firmly in response to her glance.
