A faint buzzing has started in my head. "J. Edgar Hoover?"

"The man himself. The file can't be opened for nine more years. Not without a vote by Congress. There's no telling what you've stepped into. Hoover used the rubric of Vietnam to conceal a multitude of sins during the sixties."

I'm so lost that I don't even know what questions to ask. "What about the names? The agents."

"I'm going to send a fax to your office. A list of agents working out of the Jackson, Mississippi, field office in the summer of sixty-eight. I don't know how complete it is, but it's the best I can do. Personal memoirs from the period might help you narrow it down."

"I owe you big-time for this."

"Yes, you do. Listen, the Bureau has been very supportive of Mississippi prosecutors this year, providing files on these old civil rights cases. Even if the files embarrassed us a bit. This file is obviously different. I'd think long and hard about pursuing it."

"I will."

"Watch your back, buddy."

And with that he is gone.

I pull back onto the highway, heading toward my parents' house. I suddenly have a lot to do today, but I can't do it with a murder weapon in my car. Accelerating through the bypass traffic, I punch in my office number and get Cilia, who tells me Lutjens's fax is already coming through.

"No cover page. It looks like a list of some kind. Sixty or seventy names. Social Security numbers too."

I say a silent thank-you to Peter Lutjens.

"There's a handwritten note at the bottom. It says, 'If you telephone anyone on this list, you've announced your interest to Washington.' Penn, what's going on?"

"You don't want to know. Those names belong to FBI agents, probably all retired. Find phone numbers for every one you can. Then start calling them. Give them the usual line: you're working for me, researching a novel. I need to know which agents worked in Natchez, Mississippi, in the summer of 1968. Particularly on the Delano Payton case. Okay?"

"Delano Payton. No problem."

"Fax a copy of the list to my father's medical office."

"Right."

"And, Cil?"

"Yes?"

"Use a fake name on these calls."

"I will. I'll- My God, a KHOU truck just pulled into the driveway. Got to be about the Hanratty execution."

"You can handle them."

"You got that right. I'll call you."

She rings off.

As I punch End on the cell phone, I see my hand shaking. I am crossing a line I have crossed only a few times previously, and always with a sense of euphoria mingled with dread. In the great train of cases that crossed my desk as a prosecutor, a few engaged not merely my mind or my talents or even my heart. A few penetrated the deepest springs of my being: my fears, my prejudices, and my desires. When that happened, I became more than a lawyer. I became a personification of justice. And not justice as the law defined it, but as / did.

That is how I feel now.

Last night, when Ike Ransom told me Leo Marston was involved in a thirty-year-old capital murder, I wanted to believe it, but some part of me refused. I could see no possible connection between Marston and his supposed victim. But when Peter Lutjens said the words "J. Edgar Hoover" and "national security," a circuit closed somewhere in my brain, sparking the faintest glimmer of understanding. Leo Marston is a political man from a political family, and if the Delano Payton murder had a political angle sensitive enough for the file to be hidden from public view, then a connection to Leo Marston no longer seems impossible.

Twenty years ago, that ruthless bastard wronged my father, hurt my mother, and stole my future. He did not suffer one moment for doing that. He lived as men of his kind always have: exempt from justice, untouchable. But now, far in the distance, he has come into sight, like a buck on a high ridge line. And this time I have a weapon in my hands. That weapon is a dead man. Del Payton.

CHAPTER 15.

The district attorney's office is in a three-story building near the courthouse, and there are open parking spaces out front. I take one, then trot up the stairs beside the brass plaque with Mackey's name on it. There is no receptionist, only a long hall with offices on both sides and a black custodian working in a broom closet at the far end. I walk past partly open doors until I see Mackey sitting behind a desk, wearing one of those striped oxford shirts with a white collar that I always found a little too precious.

Pushing open the door, I see a heavyset woman sitting across from Mackey's desk. "I'm sorry. I'll wait."

As I close the door, I hear Mackey say, "Excuse me just a moment, ma'am." He steps into the hall, looking put upon by the unannounced visit. "What do you want, Cage?"

"I came to see if you have any files on the Del Payton murder."

His fair-skinned face goes red, making him look like a pissed-off fraternity boy. "Do you have wax in your ears? I told you last night there was no file. I also said I'd give you no assistance unless you're the attorney of record for a member of the Payton family."

"Let's say I am."

He swallows, brought up short. "Are you or aren't you? I checked with the bar association this morning. They told me you're licensed to practice in Mississippi."

"Put it this way, Austin. If you insist on being a pain in the ass, I'm a lot more likely to be."

His lips disappear into a tight seam.

"What about the file?"

"There is no file. After the party last night I stopped by here and checked, just to be sure. All the records from 1966 through 1968 were destroyed in a fire when you and I were still in grade school."

This throws me. My first instinct is to ask whether Leo Marston was still district attorney during that fire, but I don't. Mackey isn't Clarence Darrow, but if I appear too interested in Marston, he'll zero in on my real motive quickly enough. And Marston will instantly hear about it.

"What about the police department?"

"The chief won't show you files on an unsolved murder case."

"Is he actually investigating the case?"

"What do you think?"

"I think he may be investigating it before the week is out, whether he wants to or not. What about the sheriff?"

Mackey reaches backward and pulls his door completely shut. "Why do you have a bug up your ass about this? I don't remember you as a flaming liberal."

"I'm not. I'm a flaming humanist. I happen to care that some poor son of a bitch was blown to pieces and his family never saw justice done."

A strange light comes into Mackey's eyes. "I've got it now. You don't give two shits about Del Payton or his family. You want a best-seller out of this. Maybe get yourself on Oprah's book club? Penn Cage, whitebread crusader for justice."

"Yeah, that's it."

Mackey draws himself to his full height, positive that he's divined my true motive. Greed is something he can understand. "You may be willing to drag this town through the mud for a dollar. I've got more loyalty than that. Don't come back here unless you've got new evidence in your hands."

He goes back into his office and softly closes the door.

As I turn toward the stairs, I hear footsteps closing quickly on me from behind. I whirl and find myself staring at the black custodian who was standing at the broom closet before. He's over sixty, with bluish skin and pink blemishes like freckles below his eyes, and he reeks of cigarettes.

"Keep walking," he says.

I move toward the staircase, the custodian on my heels.

"I heard you ask about Del Payton. Mackey tell you all them files burned up in a fire?"

"Yes."

"Some did, some didn't. Everything that's left is down in the basement. Five, six boxes."

I stop on the landing. "Is the basement locked?"

"Yep." He looks up and down the empty stairwell. "The door's out back. If you was to check there in about five minutes, you might find a key. When you done, leave it where you found it."

He shuffles down the stairs without another word.

I wait a few moments, then walk out onto the street and stare across at the oak-shaded courthouse. Sifting through old legal files could take some time. I need to move my father's car in case Mackey comes out before I'm done. When I stopped at my parents' house to take care of the Smith & Wesson, I found that the glass in the BMW had been repaired. I gave the Maxima back to Mom, so that if anyone targeted the BMW again, it would be me, and not my mother and daughter, who took the risk. I also transferred the remaining $25,000 into the trunk of the BMW, meaning to get it back to my father before the end of the day. Climbing inside the car, I pull around the corner, call directory assistance for the number of the Examiner, and have them connect me.

"Caitlin Masters, please."

"Ms. Masters is in a meeting. Would you like me to transfer you to her voice mail?"

"Tell her Penn Cage is on the phone."

"Sir-"

"Please just do it."

Thirty seconds later, Caitlin says, "You'd better not be standing me up for lunch."

"I do need to postpone. Something's come up."

"What could be more important than me?"

"Actually, I was going to suggest dinner tonight."

"Who says change is bad? Does eight o'clock work for you?"

"Yes. Thanks, Caitlin."

"You can repay me with information."

I hang up laughing, then lock the car and hurry into the inner square of the block. It harbors parked cars, dumpsters, and fire escapes, but thankfully no people. At the rear of Mackey's building, eight concrete steps and a green handrail descend to a steel door. There's no key in the lock. I go down the steps and feel beneath the crack of the door. Nothing. In the lee of the bottom step lies a broken, rust-colored brick. I bend and lift it.

The key is there.

The basement is lighted by bare hanging bulbs, and it stinks of mildew. I feel like I'm breathing fungus. What I first perceived as walls are stacks of boxes, hundreds of them, old bellied cardboard things that look like they were stolen from a grocery store trash pile. Thankfully, there are dates scrawled on them in black magic marker.

There seems to be no organizing concept. Files from the 1920s have been stacked next to files from the 1970s. I scan the wall of dates as though searching for my size in a display of blue jeans. No luck. But after twenty minutes of digging through rat droppings and dust, I find a short stack of boxes labeled '73 fire.

Dragging the stack into the nearest pool of light, I open the top box and riffle through its contents. The files inside are charred, stained, and mildewed, and all date from 1966. I set that box aside and open the next one. My pulse quickens. The files inside are dated 1968.

Starting at the front of the box, I examine the first page inside each folder. Marston's name is all over the files, but none deals with Delano Payton. When I get to the end of the box, I go back to the beginning and flip through every sheet in every folder, but again I find nothing. One by one I go through each folder in the boxes dating from the fire with painstaking care, but I find nothing related to Del Payton.

It looks like Mackey was telling the truth.

After restacking the boxes, I lock the door, put the key back under the brick, and climb back into the sunlight. The custodian is standing thirty yards away, smoking a cigarette in the shadow of a nearby building. I walk straight up to him like a tourist asking for directions.

"Mackey was right."

He spits on the concrete. "Shit."

"You don't happen to clean the police station, do you?"

He shakes his head.

"I guess that's it, then. I appreciate your help." I start to leave, but he reaches out and touches my elbow.

"You know, we had a couple of black police chiefs. The first one was back in 'eighty-one. I knew him pretty good. He didn't mind stepping on toes to get the job done, so they fired him after a few months. He might know something."

"What was his name?"

"Willie Pinder."

"Does he still live in town?"

"He stay over to Gaylor Street. Blue house. Drives a old Dodge pickup."

"Would he be home during the day?"

"I believe he 'tired. You could see."

"I'll call him. Hey, I never got your name."

"That's right. You watch your ass, Penn Cage. And tell your daddy Zoot say hello."

He grinds his cigarette beneath the heel of a cheap work boot and walks back toward the D.A.'s office.
