At this distance, Juan could see it was a family in the car. The wife’s head was covered in a scarf, so her face was a pale oval in the flashlight’s glow. She held a baby over her shoulder and was bouncing it gently. He could hear its crying over the wind. A second child was standing in the backseat. Though he couldn’t understand the words, he could hear the tension in the voices as the father argued with the cop.

“Is this stop legit or a case of mordida?” Linc asked, using the Spanish word for bite and the Mexican euphemism for bribery.

Juan was opening his mouth to reply when suddenly the cop pulled back from the open car window and yanked a pistol from his holster. The woman’s startled scream echoed across the night, pitched even higher than the infant wailing in her lap. The husband in the driver’s seat threw up his hands in supplication.

Car doors were flung open as the other two police officers jumped from their vehicles, both going for the automatics on their hips. One strode toward the passenger’s side of the sedan while the other raced toward Cabrillo and his team, his pistol leveled at the cab.

Juan’s wary apprehension turned into instant fury because he knew they were going to be too late.

Mark Murphy yanked open the glove compartment and a tray automatically slid out and opened to reveal a flat-panel display and a keyboard with a small joystick. As he fumbled to activate the forward-mounted machine gun, the cop who had been leaning into the car fired.

The hapless driver’s head exploded in a red spray that coated the inside of the windshield with blood and gore. It obscured Cabrillo’s view of the gunman firing twice more. The woman and her baby’s cries were cut off mid-keen. A fourth shot, and Juan was certain the kid in the backseat was dead in what he now knew was a shake-down gone bad.

Instinct took over. Cabrillo jammed the transmission into gear and hit the pedal. Acceleration wasn’t the Pig’s strong suit, but it lurched from a standstill like a snarling animal. The cop running for them stopped and opened fire. His bullets gouged harmless craters into the safety glass or ricocheted off the truck’s armored plate.

“Got it,” Mark yelled.

Juan glanced over for a second. The video screen showed a camera mounted beneath the secreted machine gun that gave Mark an aiming reference. The gun had lowered itself so the barrel peeked from under the bumper.

“Do it!” Juan snapped.

Mark keyed the weapon, and a juddering vibration rattled the truck while a plume of fire erupted under the cab. Bullets tore into the road in a line aimed straight for the nearest gunman. The corrupt cop turned to run to his left but made his move too early. He gave Murph ample time to adjust his aim. The rounds took the cop in the calf, and then walked up his body, punching holes into him at a rate of four hundred rounds a minute. The kinetic force drove him to the asphalt and rolled him once so he lay faceup. His torso looked as if he’d been mauled by a lion.

The cop who had gunned down the family lunged for his car while the third retreated back to his. Mark lifted the trigger as soon as the first one was down and swiveled the barrel to take on the third killer. Rounds pummeled the car, blowing out its windshield and side windows and shredding the bodywork. Both tires deflated, and the vehicle settled closer to the road. The gunman found temporary cover behind the partially closed door but must have understood his position was untenable. He scrambled across the seat, threw open the far door, and fell to the ground on the opposite side of his cruiser. He hunkered behind the front tire and kept low as autofire raked the vehicle.

For the moment, he was neutralized, so Juan cranked the wheel over and steered for the other car. The triggerman was halfway into his seat when the Pig’s powerful halogen lights swept across the car and then centered on him. He raised his pistol and fired as fast as the gun would allow. His rounds had no more effect than his partner’s on the truck bearing down on him.

Cabrillo felt nothing but cold rage as he drove straight for the murderer.

“Brace yourselves,” he said needlessly an instant before the Pig barreled into the cruiser.

There was a terrific crunch of metal as the door slammed into the gunman’s body, cutting off one leg at the ankle, one arm at the wrist, and his head. The impact skidded the police cruiser until its tires hooked on the macadam and the car flipped on its roof.

“First car! First car!” Linda cried from the backseat.

Juan looked over to see the driver was reaching into the cruiser. No doubt going for his radio, he thought. He had no time to turn the ponderous truck to line up the .30 caliber, so he pulled the FN Five-seveN from its hiding place and tossed it back to Linda. She caught it one-handed while the other hand was cranking down her bulletproof window.

She thumbed off the safety and opened fire as soon as she had the room to stick the gun out the window. Linc reached over to keep cranking it down to give her a better field of fire.

Linda’s angle was all wrong to hit the gunman, so as the window lowered she thrust her upper body out of the truck, bracing herself by gripping the big side mirror with her left hand. She then fired. She was cycling the trigger so fast the distinctive whip-crack of the Five-seveN sounded like a string of firecrackers.

Cabrillo was about to caution Linda that he suspected there was a fourth shooter manning the checkpoint when the crooked cop emerged from behind a dune near the shoulder of the road and opened up with a machine pistol. The weapon was woefully inaccurate at this range, and at five hundred rounds a minute it took only four seconds to unload its long magazine. Rounds whipped around the Pig, flying off when they struck the armor and starring the glass when they hit the windshield. One round flew through the open window over Linda’s hunched backside and struck the doorframe an inch from Linc’s head. The impact gouged a sliver of metal off the frame that sliced into the ex-SEAL’s neck. Had the angle been just a few tenths of a degree different, the shrapnel would have sliced his jugular.

Pressing one hand to his bleeding neck, Linc had the wherewithal to grab Linda’s ankles when Juan spun the wheel to put the armored side of the Pig between them and the shooter. He barely kept her from tumbling to the road.

“You’re hit,” she said when she saw the blood oozing through his fingers.

“I’ve cut myself worse shaving in the morning,” Linc deadpanned. However, he didn’t demur when Linda unclipped a first-aid kit stored under her side of the bench seat.

Cabrillo had spun the Pig in a tight turn to line up the underslung .30 caliber for another go. Linda’s actions had bought them the few seconds they had needed. Her cover fire had pinned the gunman behind the cruiser once again, and only now was he reaching back in to work the radio.

Mark opened fire as soon as he had a shot. He wasn’t aiming for the driver’s compartment. The shooter was too well protected. Instead, Mark riddled the rear of the vehicle until gasoline gushed from the perforated tank. Because every seventh round was a magnesium-tipped tracer, it took only a second-long burst to ignite the growing lake. Flame blossomed from under the car in a concussive whoosh that was strong enough to lift the car’s rear end off the asphalt. The Libyan started running for the desert but wasn’t fast enough.

The mixture of fuel and air in the tank exploded spectacularly, flipping the car into the air, its undercarriage burning like a meteor as it cartwheeled. It crashed into the dirt a few feet from the fleeing gunman and kicked up a flaming spray of dust that engulfed the man. When it cleared, his clothes were burning, flaring like a torch. He dropped to the ground, trying to smother the flames, but he was soaked in gasoline and the fire refused to die.
