"That Dodge is getting suspicious."

She nodded. "Jon, you think it's referencing our location on a grid?"

He considered this. "You mean tracking targets over time instead of-"

"Enough!" The lieutenant pointed. "We've got incoming!"

Another sedan vectored toward them while the Dodge seemed to observe. The second car was accelerating fast.

The lieutenant shook his head. "Fuck this! Run for the waterline!"

Ross grabbed his arm. "It could be testing us! Stand still!"

The lieutenant pulled free. He and his men sprinted in a ragged line toward the jetty, opening fire on the cars as they ran.

The moment they did so, the incoming car targeted them, and the nearby Dodge accelerated past Ross and Philips, also giving chase. She cringed as it streaked past just feet to her left.

"Jon, what's happening?"

He pulled her close. "Wait, Nat!" He saw three more cars racing in-one headed toward him and Philips. Ross hurled the flare in its direction and then tugged on the jacket sleeve. "Run! Now!"

The lieutenant fired at another incoming car as he sprinted toward the waterline, but the first sedan overtook him, tossing his body up over its hood and smashing him into its windshield, then up over the roof. He flipped three times, then landed on the pavement just in time for the Dodge to gore him. His body jammed in its undercarriage and was dragged away. The other men scattered as AutoM8s ran them down. Sporadic gunfire was quickly replaced by the shrieks of injured men crawling toward safety as the cars circled back for the kill.

Philips glanced back reflexively. "What's happening?"

"Just run!"

He led Philips on a different, longer tack to the shoreline-away from the feeding frenzy of the AutoM8s. He and Philips were nearly at the water. Another car roared up behind them. Ross pulled hard on the jacket sleeve. They had reached the jetty stones.

"Jump!"

He could see her grit her teeth-going on blind faith in him. They arced out into air, splashing into the freezing water as the car hurtled inches over their heads. It landed ten feet beyond them and sent up a splash wall thirty feet high.

Ross and Philips both came up flapping their arms, Philips coughing up water. Ross grabbed her around the neck from behind and swam back toward the jetty stones again as the tail of the bobbing sedan settled back into the water, nearly coming down on her head. It flopped onto the waves, bubbling and hissing around them.

She sensed that something large had just missed her. "Jon!"

"It's okay! Wait. It's sinking."

"Where are the others?"

"They're gone."

She panted as they bobbed there for several seconds listening to bubbling water and distant engines on the tarmac above. His arm still around her. Soon there was just hissing.

"Okay, swim. Follow my voice."

Merritt cradled the UMP on the bike's broad gas tank and swerved from side to side trying to get around Loki's BMW. Each time he approached, Loki stabbed on the brakes. Finally the road widened again. The corrugated fences of salvage yards and aging factories now fronted it. Merritt accelerated rapidly, roaring alongside the car.

He searched for some weakness in the armor and noticed that brushed steel knobs appeared at regular intervals on the roof, hood, and trunk. They looked like high-end cell-phone antennas-a dozen of them, evenly spaced.

Merritt braked and swerved as Loki tried to smash him into a line of parked cars. Merritt accelerated around the other side and lifted up the UMP. He glanced at the road, then took careful aim at the car. He fired a short burst. The shots ricocheted off the roof.

Loki swerved toward him again, and instead of dodging away immediately, Merritt let him come in closer. He took more careful aim and fired again-nailing a metal knob.

And barely denting it.

"Son of a bitch."

Behind Merritt eight sedans screeched in from side streets. He glanced back over his shoulder to see them surging after him. He raised the UMP one-handed and opened up with short, controlled bursts. The front tires of first one, then another blasted out, and they quickly fell behind as the others accelerated. He knocked out the tires on still a third.

The gun was empty. Merritt turned forward and saw ten more unmanned cars come in from side streets up ahead.

No way to reload. Time to concentrate. He tossed the UMP onto the hood of a nearby car, then ripped the throttle and drove howling past Loki.

Merritt dodged a hatchback emerging from a parking lot-which turned out to be a regular car with people in it. An onrushing AutoM8 immediately broadsided it. Half a dozen more AutoM8s streamed in from side streets behind him.

Merritt turned forward again to see the AutoM8s approaching up ahead, surging his way in interlocking slaloms. It was an impenetrable roving barrier. A demonstration of networked swarming behavior that no human drivers could match. Merritt had a couple of seconds at most. A score of AutoM8s were all around him, closing fast-more coming in every second.

He looked back at Loki's BMW, then swerved and stabbed the brakes-bringing himself just feet off Loki's front bumper. Still going seventy, he eased back on the throttle and, taking a breath, released his hold on the handlebars, falling backward onto Loki's front hood as the BMW bumped his bike's rear tire. The bike veered forward and to the side and was immediately crushed by a wall of oncoming AutoM8s, which raced past only inches to either side of the BMW. Several smashed head-on into pursuing AutoM8s, exploding into a whirlwind of plastic parts, glass, and tumbling metal.

Merritt hit Loki's hood hard, then slid back into the windshield. He rolled left, jamming his foot down onto a brushed metal knob at the corner of the hood, and clamped onto the wiper well with his hands. He braced his other foot against the knob on the far corner like it was a rock-climbing wall.

He glared into the blacked-out windshield and pointed threateningly. You're not rid of me yet, asshole.

From the backseat of the BMW, Gragg stared in amazement at his pursuer now straddling the car hood. "You have got to be shitting me…" He didn't see that coming. He watched the man like a television show through the glass as the guy pulled an automatic pistol from his coat and aimed at the corner of the windshield.

A series of muted cracks sounded. Divots appeared in the glass over a several-inch area. Gragg watched this calculated attempt to penetrate his armor with something bordering on admiration. The corners were typically the weakest spots on a bulletproof windshield. It was a cool-headed call-especially with scenery racing past behind him.

Too bad the glass was three inches of polycarbonate laminate that could stop a rifle bullet. A score of AutoM8s now surrounded Gragg's BMW in close order like a slavering pack of wolves. Gragg shook his head sadly and shouted at the windshield. "What now, crazy man? You're on an armored car! What were you thinking?"

Beyond the windshield the rider had reached down to his shoe and now brandished a killing knife as he braced himself with both feet and his other hand.

Gragg laughed. "Look out. He's got a knife!"

The rider turned, jammed the knife under the bottom edge of a satellite uplink node, and pried upward. The node peeled off with a shriek of bending metal.

The Voice came over the stereo system. "Uplink…one…of…twelve…has failed."

Gragg felt the rage building. "You son of a bitch! You're going for a ride now!"

With a wave of his gloved hands, the BMW went into a power slide and the rider was nearly flung off.

The Major's chopper came in low and fast over the industrial area, banking so that nothing but brick factory buildings were visible in the left windows. The Major clipped a monkey cord onto his harness and gave it two test pulls. He struggled to his feet as the chopper leveled off. The old wound in his knee was already acting up. An image of a mortar shell landing next to him in a patch of Nicaraguan mud flashed in his mind. Ancient history.
