They mumbled greetings and parted to let Sebeck and Mantz pass.

Detective Martin Burkow, a corpulent man in his fifties with ill-fitting pants, stood on a mound of sandy soil at the edge of the road. Next to him the police photographer leaned forward to get an overhead shot of a body lying in the road. A pool of brownish, dried blood stretched out beneath it and traced dark rivulets downhill.

Sebeck gazed over the scene. A motocross motorcycle lay twenty yards down the road, on the side of a nearby hill. He could see where it had bounded into the left wall of the canyon and then rolled back across the dirt road.

Above the road, between him and the body, a taut steel cable stretched at neck level. The cable traversed the road at a forty-five-degree angle, closer on the left side, farther away on the right. Anything racing through here would grind down the cable like a saw blade. The cable was bloodstained for a good ten-foot length. The body lay ten yards beyond that. A motorcycle helmet five yards farther still.

Sebeck's eyes followed the thin steel cable rightward to a steel pole rising from the chaparral. Then leftward through the bushes. A freshly cut groove crossed the dirt roadway directly beneath the cable.

"Martin, what do we have?"

Detective Burkow coughed the consumptive cough of a lifelong smoker. "Hi, Pete. Thanks for coming down. Caucasian male, approximately thirty years old. A local walking his dog found the body about an hour ago. It was reported as a 10–54, but I thought I'd call you guys. This is looking more like a 187."

Sebeck and Mantz looked at each other and raised their eyebrows. Homicide. Rare in Thousand Oaks. The only killings down here were made in real estate.

The photographer nodded to Burkow and made his way back along the edge of the road. Burkow motioned for them to move forward. "Stick to the left, in the ruts. All the footprints are on the other side." He stepped down off the mound.

Sebeck and Mantz ducked under the cable and stood over the body. Sebeck was relieved to see the head still attached. The nearby helmet was empty. The dead man wore an expensive-looking motocross jumpsuit with logo patches. The yellow nylon was torn at chest level. It looked like he hit the cable with his torso, and it rode up to his throat. The man's larynx was slashed, and flies buzzed over the gaping wound. His skin was alabaster white, and his lusterless, dry eyes stared at Sebeck's shoes.

Sebeck pulled on rubber surgical gloves and leaned forward. He felt for a wallet or ID in the pockets. There didn't appear to be any. He looked ahead at the dirt bike, then back at the police photographer. "Carey, try to read the plates on the bike. Maybe we can ID this guy."

The photographer peered down the canyon, then affixed a 200mm lens to his camera and focused on the motorcycle.

Sebeck stood up, and his eyes once again traversed the cable behind them. He peered through the bushes where it disappeared. "Anybody know where this ends?"

The deputies and EMTs shook their heads.

"Nathan, let's follow this thing. Stay clear of it. And look for tracks." He turned back to Burkow. "Marty, what are all these footprints on the road?"

"The locals walk it all the time. I've already interviewed a few."

"Get me a cast of every unique print in this area." Sebeck waved his arms downward.

"That's gonna be a lot of prints."

"Tell forensics they don't have to cast the dog tracks."

Mantz grinned. "I don't know, I hear Pekinese are pretty smart."

Sebeck shot him a dark look and pointed at the bushes. The cable led through a gap in the hillside that opened up back onto Potrero Road. He and Mantz fanned out on either side and moved through the bushes while studying the sandy ground.

"Keep an eye out for rattlesnakes, Pete." Mantz jumped over a ditch of eroded soil.

The cable was easy to follow, and the groove in the soil beneath it shadowed it all the way. After sixty feet they were back at the chain-link fence on Potrero Road, staring at the back of a No Trespassing sign. The cable ran through the fence and into the back of a steel box two feet square sitting atop a thick pipe driven into the ground. The groove in the soil ended six feet away from the fence on their side. They had found no new footprints.

"Let's head to the other side."

In a few minutes they were back on Potrero Road at the gate. They walked a hundred yards down the shoulder and reached the front of the steel box. It had a sturdy lock in its face and was fashioned of welded steel. It had a few indentations where passing teens had taken potshots at it with rifles, but none had penetrated.

"Built to last." Sebeck peered around to a square hole in back where the cable entered. "Winch housing?"

Mantz nodded. "At first I thought it might be kids playing an evil prank. But this is a serious piece of engineering. What use could this thing serve?"

They turned as a Range Rover and a pickup truck pulled to the shoulder of the road near the gate. A couple of guys in khakis got out of the Rover. They spoke briefly with the deputies there, who pointed down to Sebeck and Mantz. The khakis climbed back into the Rover. Both vehicles rolled down the shoulder and stopped in front of the detectives, sending a choking cloud of dust over them.

The khakis got out again. The one on the passenger side came forward with his hand extended. He looked like money-business casual with creases. "Detectives. Gordon Pietro, senior legal counsel for CyberStorm Entertainment." They shook hands. Pietro pushed business cards on both of them. "This is our VP of public relations, Ron Massey."

Sebeck nodded. Massey had longer hair than Pietro and a pierced eyebrow with a gold ring. He was in his late twenties and looked like money, too. A pang of jealousy shot through Sebeck. The fact that he could effortlessly beat the shit out of this kid sprang unbidden into his mind. He pushed it back down. "This is Detective Mantz. I'm Detective Sergeant Sebeck, East Ventura County Major Crimes Unit."

Pietro stopped short. "Major Crimes Unit? We were told there was an accidental death on the property."

"The responding officers called us in. We're investigating this as a potential homicide." Sebeck leaned around Pietro and looked at the pickup truck parked behind the Rover. The pickup had a logo on the side door, illegible at this angle. "Who's in the truck?"

"Oh- a worker from the management firm. They maintain the property. He has a remote for the front gate."

"Let's get him out here. I want to talk to him."

Pietro walked back, motioning to the guy in the truck.

Sebeck turned to Massey. "What's this property used for?"

"CyberStorm purchased the land as an investment. It's also used by the company for campouts, team-building exercises, things like that."

Sebeck took out a pad and pen. "So you're the PR guy? What's CyberStorm Entertainment do, Ron?"

"We're a leading computer game developer. Ever hear of Over the Rhine?"

"No."

Burkow shouted from down near the gate. "Pete. I got a name from the DMV. The bike's registered to a Joseph Pavlos. Lives up in those McMansions on the hilltop."

Massey put a hand to his chin. "Oh man."

"You know the victim?"

"Yeah. He's one of our senior developers. What happened?"

Sebeck gestured with his pen. "He hit this cable with his neck. Do you know if he rode down here regularly?"

"I don't, but his development team might."

Pietro returned with a Mexican man in his forties dressed in a green jumpsuit. The guy looked like he'd had a tough life-and that he expected it to get a lot tougher any second.

"Ron? Pav was the one killed?"

Massey nodded and produced a cell phone. "Damn this canyon. Can't get a signal."
