"Banner."

"Ah. As in 'star-spangled.' "

Jonah hesitated. "How'd you know? Camilla came up with the name, but you're the first to get it."

"Just a raggedy-ass guess."

Odessa gestured. "Sit down. Are you having lunch?"

Jonah promptly held out his plastic basket. "Here. You can have half of mine. Camilla's bugging me to diet. I bet I picked up fifteen pounds in the last few months of her pregnancy. Hers came right off, but I can't seem to get rid of mine." The hunk of flesh he pinched on his side formed a considerable sausage between his thumb and index finger.

I was standing closest to him and thought it'd be too conspicuous if I circled the table and settled beside Odessa, so I sat down on the bench beside him. I checked Jonah's sandwich, which was cut on the diagonal: bacon, lettuce, and tomato, with a gruel of guacamole in between the layers of mayonnaise. I added a snow flurry of salt to the mix. I hate to pass up a chance to give my kidneys a thrill.

"What are you up to?" Odessa asked. He'd caught me with a mouthful of sandwich, and while I struggled to clear my palette, he went back to their conversation. "We were just talking about Purcell. Jonah attended the post."

"Such as it was. Condition of the body, Dr. Yee says he can't run biochemical or biophysical tests. From the gross, it looks like he died from a single contact shot to the head. We found the gun on the front seat. A Colt Python .357 with one shot fired. The cartridge casing was still in the cylinder. Yee says there's a 99.9 percent probability he was dead when he went into the water."

"The gun was his?" I asked.

Jonah wiped his mouth and then crumpled the paper napkin in his hand. "He bought it before he and Fiona split. Crystal wouldn't let him keep it in the house on account of the kid. She thinks he either kept it in his desk drawer at work or in the glove compartment of his car."

Odessa said, "We're trying to figure out how he got up to the reservoir in the first place."

I raised my hand. "He was supposed to go see Fiona. She says he never showed, but she could be lying."

Odessa nodded happily, his mouth full. "Don't think it's escaped our attention that the guy turns up dead practically in her front yard."

"And catch this. She's the sole beneficiary on a life insurance policy. Part of the divorce settlement. We checked it out," Jonah said.

"How much?"

"A million."

"That would do it for me," Odessa said.

"Risky to kill the guy so close to home," I remarked.

"Maybe that's the beauty of it," Jonah said. "Could have been someone else. Lure him up there on some pretext and put a bullet in his head."

Odessa made a face. "How're you going to get him up there?"

Jonah said, "Ride in the same car. You call and arrange a meeting, say you want to go some place quiet and talk about a situation, but you need a lift."

"What's the pretext?"

I said, "Who needs a pretext? You hide in the backseat and pull the gun on him."

"Then what? How do you get back down the road in the dark?"

Jonah said, "You hike. It's not that far."

I said, "What if you're seen? Now you've got someone who can place you at the scene."

Odessa said, "Could have been two of them. One meets him up there and does the job while the other one waits in a car parked somewhere down the road."

"But doesn't adding a coconspirator increase the risk?"

"Depends on who it is."

Jonah sipped his Coke. He offered me the cup and I took a sip as well. We were silent for a moment, contemplating the images before us.

I said, "On the other hand, Purcell was in trouble with the feds and facing social disgrace. He must have considered suicide. Wouldn't you in his shoes?"

Jonah said, "I guess." He sounded glum at the prospect. "The guys are still working on the Mercedes. He had this mohair blanket over his lap, empty whiskey bottle on the floor of the passenger side. Headlights off. Key in the ignition, which was turned to the On position. Radio's off. ID, his wallet, all of that was on the body, including his watch, which is still running by the way. Damn thing didn't lose a second after all those weeks."

Odessa perked up at that. "What make? Hell of an endorsement. We should get in touch with the company."

"Breitling, watertight down to four hundred feet."

Odessa said, "Remember that ad with the fountain pen?"
