I put on my sunglasses, folded my seersucker coat over my arm, and looked across the street at a black man selling rattlesnake watermelons off the tailgate of a pickup truck.

"If y'all want to act like public clowns, that's your business," I said. "But you'd better wipe that stupid expression off your faces when you're around my partner. Also, if I hear you making remarks about her, either to me or somebody else, we're going to take it up in a serious way. You get my drift?"

Arceneaux rotated his head on his neck, then pulled the front of his shirt loose from his damp skin with his fingers.

"Boy, it's hot, ain't it?" he said. "I think I'm gonna come in this afternoon and take a cold shower. You ought to try it too, Dave. A cold shower might get the wrong thing off your mind."

They walked into the shimmering haze, their leather holsters and cartridge belts creaking on their hips, the backs of their shirts peppered with sweat.

Rosie Gomez and I turned off the highway in my pickup truck and drove down the dirt lane through the pecan orchard toward Spanish Lake, where we could see elevated camera platforms and camera booms silhouetted against the sun's reflection on the water. A chain was hung across the road between a post and the side of the wood-frame security building. The security guard, the wiry man with the white scar embossed on his throat like a chicken's foot, approached my window. His face looked pinched and heated in the shadow of his bill cap.

I showed him my badge.

"Yeah, y'all go on in," he said. "You remember me, Detective Robicheaux?"

His hair was gray, cut close to the scalp, and his skin was browned and as coarse as a lizard's from the sun. His blue eyes seemed to have an optical defect of some kind, a nervous shudder like marbles clicking on a plate.

"It's Doucet, isn't it?" I said.

"Yes, sir, Murphy Doucet. You got a good memory. I used to be with the Jefferson Parish Sheriff's Department when you were with N.O.P.D."

His stomach was as flat as a shingle. He wore a.357 chrome-plated revolver, and also a clip-on radio, a can of Mace, and a rubber baton on his belt.

"It looks like you're in the movie business now," I said.

"Just for a while. I own half of a security service now and I'm a steward for the Teamsters out of Lafayette, too. So I'm kind of on board both ways here."

"This is Special Agent Gomez from the FBI. We'd like to talk to Mr. Goldman a few minutes if he's not too busy."

"Is there been some kind of trouble?"

"Is Mr. Goldman here?"

"Yes, sir, that's him right up yonder in the trees. I'll tell him y'all on your way." He started to take his radio off his belt.

"That's all right. We'll find him."

"Yes, sir, anything you say."

He dropped the chain and waited for us to pass. In the rearview mirror I saw him hook it to the post again. Rosie Gomez was looking at the side of my face.

"What is it?" she said.

"The Teamsters. Why does a Hollywood production company want to come into a depressed rural area and contract for services from the Teamsters? They can hire labor around here for minimum wage."

"Maybe they do business with unions as a matter of course."

"Nope, they usually try to leave their unions back in California. I've got a feeling this has something to do with Julie Balboni being on board the ark."

I watched her expression. She looked straight ahead.

"You know who Baby Feet Balboni is, don't you?" I said.

"Yes, Mr. Balboni is well known to us."

"You know he's in New Iberia, too, don't you?"

She waited before she spoke again. Her small hands were clenched on her purse.

"What's your implication?" she said.

"I think the Bureau has more than one reason for being in town."

"You think the girl's murder has secondary importance to me?"

"No, not to you."

"But probably to the people I work under?"

"You'd know that better than I."

"You don't think well of us, do you?"

"My experience with the Bureau was never too good. But maybe the problem was mine. As the Bible says, I used to look through a glass darkly. Primarily because there was Jim Beam in it most of the time."

"The Bureau's changed."

"Yeah, I guess it has."

Yes, I thought, they hired racial minorities and women at gunpoint, and they stopped wire-tapping civil-rights leaders and smearing innocent people's reputations after their years of illegal surveillance and character assassination were finally exposed.

I parked the truck in the shade of a moss-hung live-oak tree, and we walked toward the shore of the lake, where a dozen people listened attentively to a man in a canvas chair who waved his arms while he talked, jabbed his finger in the air to make a point, and shrugged his powerful shoulders as though he were desperate in his desire to be understood. His voice, his manner, made me think of a hurricane stuffed inside a pair of white tennis shorts and a dark blue polo shirt.

"-the best fucking story editor in that fucking town," he was saying. "I don't care what those assholes say, they couldn't carry my fucking jock strap. When we come out of the cutting room with this, it's going to be solid fucking gold. Has everybody got that? This is a great picture. Believe it, they're going to spot their pants big time on this one."

His strained face looked like a white balloon that was about to burst. But even while his histrionics grew to awesome levels and inspired mute reverence in his listeners, his eyes drifted to me and Rosie, and I had a feeling that Murphy Doucet, the security guard, had used his radio after all.

When we introduced ourselves and showed him our identification, he said, "Do you have telephones where you work?"

"I beg your pardon?" I said.

"Do you have telephones where you work? Do you have people there who know how to make appointments for you?"

"Maybe you don't understand, Mr. Goldman. During a criminal investigation we don't make appointments to talk to people."

His face flexed as though it were made of white rubber.

"You saying you're out here investigating some crime? What crime we talking about here?" he said. "You see a crime around here?" He swiveled his head around. "I don't see one."

"We can talk down at the sheriff's office if you wish," Rosie said.

He stared at her as though she had stepped through a hole in the dimension.

"Do you have any idea of what it costs to keep one hundred and fifty people standing around while I'm playing pocket pool with somebody's criminal investigation?" he said.

"You heard what she said. What's it going to be, partner?" I asked.

"Partner? " he said, looking out at the lake with a kind of melancholy disbelief on his face. "I think I screwed up in an earlier incarnation. I probably had something to do with the sinking of the Titanic or the assassination of the Archduke Ferdinand. That's gotta be it."

Then he rose and faced me with the flat glare of a boxer waiting for the referee to finish with the ring instructions.

"You want to take a walk or go in my trailer?" he said. "The air conditioner in my trailer is broken. You could fry eggs on the toilet seat. What d'you want to do?"

"This is fine," I said.

"Fine, huh?" he said, as though he were addressing some cynical store of private knowledge within himself. "What is it you want to say, Mr. Robicheaux?"

He walked along the bank of the lake, his hair curling out of his polo shirt like bronze wire. His white tennis shorts seemed about to rip at the seams on his muscular buttocks and thighs.

"I understand that you've cautioned some of your people to stay away from me. Is that correct?" I said.

"What people? What are you talking about?"

"I believe you know what I'm talking about."
