The next morning was Saturday, a blue-gray, misty, cool dawn that brought Mary Beth Sweeney to my back door at 6 a.m., still in uniform from the night shift, her thumbs hooked into the sides of her gunbelt.

I held open the screen. 'Come in and join Pete and me for breakfast. We're fixing to go down to the river in a few minutes,' I said.

She removed her hat, her eyes smiling into mine.

'I'm sorry for the other night,' she said.

'You got to try some of Pete's fried eggs and pork chops. They run freight trains on this stuff, isn't that right, Pete?'

He grinned from behind his plate. 'I always know when he's gonna say something like that,' he said.

We rode down the dirt track in my car to the bluffs. The water in the river was high and slate green, tangled with mist, the current eddying around the dead cottonwood trees that had snagged in the clay.

Five feet under the surface was the top of an ancient car, now softly molded with silt and moss. In the winter of 1933 two members of the Karpis-Barker gang robbed the bank in Deaf Smith and tried to outrun a collection of Texas Rangers and sheriffs' deputies from three counties. Their car was raked with Thompson machine-gun bullets, the glass blown out, the fuel tank scissored almost in half. My father watched the car careen off the road, plow through the corn crib and hog lot, then ignite with a whoosh of heat and energy that set chickens on fire behind the barn.

The car rolled like a self-contained mobile inferno across the yellow grass in the fields, the two robbers like blackened pieces of stone inside. The ammunition in their stolen Browning Automatic Rifles was still exploding when the car dipped over the bluffs and slid into the river. It continued to burn, like a fallen star, under the water, boiling carp that were as thick as logs to the surface.

Today the car was a home to shovel-mouth catfish that could straighten a steel hook like a paper clip.

Mary Beth got out of the Avalon and stretched and hung her gunbelt over the corner of the open door. She watched Pete baiting his hook down on the bank, as though she were forming words in her mind.

'The man at my apartment, his name's Brian. I was involved with him. But not anymore. I mean, not personally,' she said.

'Take this for what it's worth, Mary Beth. Most feds are good guys. That guy's not. He put you at risk, then he tried to lean on me.'

'You?'

'I suspect y'all are DEA. The FBI doesn't send its people in by themselves.'

'Brian leaned on you?'

'Tried. This guy's not first team material.'

Her eyes were hot, her back stiff with anger.

'I have to make a phone call,' she said.

'Stay here, Mary Beth.'

'I'll walk back.'

I took her gunbelt off the corner of the door.

'Nine-Mike Beretta,' I said.

'You want to shoot it?'

'No.' I folded the belt across the holster and handed it to her. The nine-millimeter rounds inserted in the leather loops felt thick and smooth under my fingers. 'I don't mess with guns anymore. Take my car back. Pete and I will walk.'

Then she did something that neither Pete nor I expected. In fact, his face was beaming with surprise and glee as he looked up from the bank and she hooked one arm around my neck and kissed me hard on the mouth.

That afternoon the district attorney, Marvin Pomroy, rang me at home.

'We've got Garland Moon in the cage. He wants to see you,' he said.

'What's he in for?'

'Trespassing, scaring the shit out of people. You coming down?'

'No.'

'He's into something, it's got to do with the Vanzandt family. Anyway, we've got to kick him loose in another hour. So suit yourself.'

The previous night, Garland T. Moon had showed up first at Shorty's, then at the drive-in restaurant north of town, dressed in plastic cowboy boots, white pleated slacks, a form-fitting sleeveless undershirt, costume jewelry on his hands and wrists and neck. He wandered among the cars in the parking lot, gregarious, avuncular, a paper shell of french fries in one hand, a frosted Coke in the other. He worked his way into groups of teenagers, as though he were an old friend, and told obscene jokes that made their faces go slack with disgust.

Then Bunny Vogel's '55 Chevy, with a girl in the front passenger seat, and Darl Vanzandt and another girl in back, cruised the lines of parked cars and backed into an empty space twenty feet from Moon.

He walked to their car, bent down grinning into the windows, his face lighted with familiarity.

'Who's that in there?' he said.

Inside the car, they looked at one another.

'How about we go for some beers? Maybe I score a little muta?' he said.

'We don't know you, man,' Darl said.

'You kids got a look in your eyes tells me y'all don't care y'all end up in the gutter or not… I'm a student of people. I want to know where that look comes from. Let's make it scrambled eggs at my place.'

'I just washed my car. Get your fucking armpits off the window,' Bunny said.

A few minutes later every car in the drive-in had burned rubber out onto the highway and left Garland T. Moon standing alone, with his french fries and frosted Coke, amid the litter in the parking lot.

The next day Jack Vanzandt was among a foursome on the ninth green at the country club when a man in a cream-colored suit, a Hawaiian shirt printed with flowers that could have been shotgun wounds, and brand-new white K-Mart tennis shoes with the word JOX emblazoned across the tops, strolled up from the edge of the water trap, his wisps of red hair oiled on his scalp, and said, 'Excuse me, sir, I'd like to talk with you over at the Shake 'n' Dog about a mutual interest we got… Say, this is a right nice golf range, ain't it? I been thinking about getting a membership myself.'

Garland T. Moon was in the holding cage on the first floor, by the elevator shaft that led up to the jail. He had stripped off his coat and shirt, and was standing barechested in his slacks and JOX running shoes, his hands hooked like claws in the wire mesh.

'What kind of bullshit are you up to, Moon?' I said.

'I got 'em by the short hairs.'

'Oh?'

'That little puke Darl Vanzandt done Jimmy Cole, thinks he's some kind of Satanist? I got news for y'all, there's people that's the real thing, that's made different in the womb, it's in the Bible and you can check it out. You getting my drift, boy?'

'Why'd you want to see me?'

'Tell his father I want a hunnerd-thousand dollars.'

'Tell him yourself.'

'Don't walk away from me… You gonna do what I tell you whether you like it or not. I can give testimony I heard Lucas Smothers confess to raping and killing that girl in the picnic ground.'

'Have you been in a mental asylum?'

'Where I been is in this tub of nigger bathwater when I was fifteen years old.' His mouth puckered into a peculiar grin, red and glistening, flanged with small teeth.

'It's the town, isn't it, not me or Lucas or some peckerwoods who worked you over with a cattle prod,' I said.

'You know the old county prison north of the drive-in restaurant? Forty-one years ago two gunbulls put me over an oil drum every Sunday morning and took turns. Tore my insides out and laughed while they done it… Y'all gonna get rid of me the day you learn how to scrub the stink out of your own shit.'

I turned and walked back toward the entrance.

'You won't pick up a gun 'cause you killed your best friend! I got the Indian sign on you, boy!' he called at my back.

Marvin Pomroy waited for me outside. He was a Little League coach, and because it was Saturday he wore a pair of seersucker slacks and a washed-out golf shirt without a coat. But, as always, not a hair was out of place on his head, and his face had the serenity of a thoughtful Puritan who viewed the failure of the world through Plexiglas.
