CHAPTER ONE

      “You ready for this?” Alan Reidigger asked, his voice low as he checked the magazine on the black Glock in his meaty fist. He and Zero had their backs to a plywood structure, keeping hidden and obscured by the darkness. It was almost too dark to see, but Zero knew that in moments the whole place would be lit up like the Fourth of July.

      “Always ready,” Zero whispered back. He held a Ruger LC9 in his left hand, a small silver pistol with a nine-round mag, as he flexed the fingers of his right. He had to stay cognizant of the injury he’d sustained almost two years earlier, when a steel anchor had crushed his hand to the point of uselessness. Three surgeries and several months of physical therapy later, he had regained most of its operation, despite permanent nerve damage. He could fire a gun but his aim tended to track to the left, a minor annoyance that he’d been working to overcome.

      “I’ll go left,” Reidigger laid out, “and clear the causeway. You go right. Keep your eyes up and watch your six. I bet there’s a surprise or two waiting for us.”

      Zero grinned. “Oh, are you calling the shots now, part-timer?”

      “Just try to keep up, old man.” Reidigger returned the grin, his lips curling behind the thick beard that obscured the lower half of his face. “Ready? Let’s go.”

      With the simple, whispered command they both shoved off from the plywood façade behind them and split off. Zero brought the Ruger up, its barrel following his line of sight as he slipped around the dark corner and stole down a narrow alley.

      At first it was just silence and darkness, barely a sound in the cavernous space. Zero had to remind his muscles to keep from tensing, to stay loose and not slow down his reaction speed.

      This is just like all the other times, he told himself. You’ve done this before.

      Then—lights exploded to his right, a severe and jarring series of flashes. A muzzle flare, accompanied by the deafening report of gunfire. Zero threw himself forward and tucked into a roll, coming up on one knee. The figure was barely more than a silhouette, but he could see enough to squeeze off two shots that connected with the silhouette at center mass.

      Still got it. He climbed to his feet but stayed low, moving forward in a crouch. Eyes up. Watch your six… He whirled around just in time to see another dark figure sliding into view, cutting off the path behind him. Zero dropped himself backward, landing on his rear even as he popped off two more shots. He heard projectiles whistle right over his head, practically felt them ruffle his hair. Both his shots found home, one in the figure’s torso and the second to the forehead.

      From the other side of the structure came three tight shots in quick succession. Then silence. “Alan,” he hissed into his earpiece. “Clear?”

      “Hold that thought,” came the reply. A burst of automatic fire tore through the air, and then two punctuating shots from the Glock. “All clear. Meet me around the side.”

      Zero kept his back to the wall and moved forward quickly, the rough plywood tugging at his tac vest. He spotted a blur of movement up ahead, from the roof of the flat-topped structure. A single well-placed headshot took out the threat.

      He reached the corner and paused, taking a breath before clearing it. As he whipped around, the Ruger coming up, he found himself face-to-face with Reidigger.

      “I got three,” Zero told him.

      “Two on my side,” Alan grunted. “Which means…”

      Zero didn’t have time to shout a warning as he saw the human-shaped figure glide into view behind Alan. He brought the pistol up, right over Alan’s shoulder, and fired twice.

      But not fast enough. As Zero’s shots landed, Alan yelped and grasped at his leg.

      “Ah, dammit!” Reidigger groaned. “Not again.”

      Zero winced as bright fluorescent lights came to life suddenly, illuminating the entire indoor training course. Heels clacked against the concrete floor, and a moment later Maria Johansson rounded the corner, arms folded over her white blazer and her lipsticked mouth frowning.

      “What gives?” Reidigger protested. “Why’d we stop?”

      “Alan,” Maria scolded, “maybe you ought to take your own advice and watch your six.”

      “What, this?” Alan gestured to his thigh, where a green paintball had splattered across his pant leg. “This is barely a graze.”

      Maria scoffed. “That would have been a femoral bleed. You’d be dead in ninety seconds.” To Zero she added, “Nice job, Kent. You’re moving like your old self.”

      Zero smirked at Alan, who furtively gave him the finger.

      The warehouse they were in was a former wholesale packing plant, until the CIA purchased it and turned it into training grounds. The course itself was a product of the eccentric agency engineer Bixby, who had done his best to simulate a nighttime raid. The “compound” they had been storming was made of boxy plywood structures, while the muzzle flashes were strobe lights placed throughout the facility. The gunshots were reproduced digitally and broadcast on high-def speakers, which echoed in the huge space and sounded to Zero’s trained ear almost like real shots. The human-shaped figures were little more than dummies molded from ballistic gel and affixed to dolly tracks, while the paintball
