Don’t look behind you!

  The shadow of a man appeared seemingly out of nowhere and lunged at her. She pivoted, trying to scramble away. But she wasn’t fast enough, and a hard body plowed into her with the force of a Sherman tank.

  Strong arms clamped around her like a vise and tackled her to the ground. Spitting dirt, she rolled and lashed out with both feet. Satisfaction flicked in her brain when her assailant grunted. The next thing she knew he was on top of her. With her arms bound, she could not defend herself.

  “Get off me!” she shouted.

  She caught a glimpse of dark eyes. She felt the tremendous force of his strength, and her only thought was that these were the last moments of her life.

  “If you want to live, you’ll be quiet.”

  Prologue

  The prison van swayed rhythmically as it barreled into the night, but Mattie Logan didn’t sleep. The judge’s final word rang like a death knell in her ears.

  Guilty.

  The verdict had been handed down eight hours earlier in the federal courthouse in Billings, Montana. She couldn’t believe she would be spending the rest of her life in prison. How in the name of God had this happened?

  She’d asked herself that question a thousand times in the past four months. Four agonizing months spent in a prison cell the size of a bathroom. A cell where she’d come very close to losing her mind. The only thing that had kept her going was the promise of justice. The hope that truth would prevail. Eight hours ago that hope had been ripped from her desperate grasp, and she was left with nothing but a keen sense of impending doom.

  Mattie Logan, you are hereby sentenced to life in prison.

  When she shifted on the bench seat, the shackles on her ankles and wrists rattled. The U.S. Marshal sitting across from her glanced at her over the top of his magazine but didn’t offer to loosen the cuffs. Because of the nature of her alleged crime, she’d been deemed a high security risk. The term was laughable—or terrifying, depending on your point of view. Nonetheless, three U.S. Marshals had been assigned to transport her from Billings to a federal prison facility at an undisclosed location in Washington State.

  Mattie gazed out the small window at the stark winter-dead trees silhouetted against a jagged horizon. They were traveling on a desolate stretch of highway somewhere in the mountains and heading west. The bleak scene reminded her of her life—cold and desolate—and at that moment she’d never felt more alone.

  She leaned against the seat back and tried not to think. But her scientist’s mind was always at work. It was one of the reasons she’d been hired to work on the top-secret EDNA project at the Department of Defense.

  If only she’d known….

  A loud bang disrupted the silence. The van swerved violently, tossing her against the wall. Mattie looked over to see the young marshal rise, his expression alarmed, his hand going to his sidearm. Had a tire blown?

  Then a second bang sounded. The van veered left, the force throwing Mattie to the floor. A few feet away the young marshal clutched the balance bar as he stumbled toward the cab, his eyes trained on the driver.

  “Sam, what happened?” he shouted. “Sam!”

  The driver didn’t answer. Through the windshield Mattie saw the headlights play wildly over brush and sapling trees. Fear cut through her when she realized the van was careening into a ravine.

  A violent bump sent her two feet into the air. The marshal stumbled and fell but didn’t drop his radio. “Bravo Victor Two Niner. We got a code—”

  His voice was cut off as the van pitched. Mattie caught a glimpse of the driver slumped over the wheel. Out the window, she saw sparks and debris spew high into the air. Another lurch tossed her to the opposite side of the van and sent the marshal sliding across the floor. The female marshal was shouting as she grappled for her radio.

  The lights blinked out, plunging them into darkness. The floor tilted, and Mattie began to tumble. She tried to raise her arms to protect herself, but the cuffs and shackles hindered her. A sound that was part scream, part moan tore from her throat when her head snapped back, shattering glass.

  Then suddenly the van was still. In total darkness Mattie lay on her back. Somewhere nearby steam hissed. The side door was now above her and stood open. Cold air poured in, embracing her with icy fingers. Beyond, a sliver of moon illuminated fast-moving storm clouds.

  The female marshal called out. “Is everyone all right?”

  “I think my leg’s broke,” came a weak voice.

  “What the hell happened?” came a third.

  “Logan? You okay?”

  Mattie did a quick physical inventory. Her head hurt. Raising her hand, she touched her temple, felt the wetness of blood. “I’m cut.”

  “Stay put.” One male marshal groaned as he rose.

  “What about Sam?” the female marshal asked, referring to the driver.

  Mattie looked toward the cab. By the light of the moon she could see that the driver was slumped across the seat at an odd angle.

  “I’ll check.??
? One of the male marshals went to the driver.

  “We’ve got an engine fire,” came another voice.

  “Let’s get everyone out of the van.”

  Mattie shoved herself to a sitting position and looked around. Through the cab window she saw the yellow flicker of flames coming from the engine. Somewhere in the van, the injured marshal groaned in pain.

  The other male marshal came up beside her and squatted. “I’m going to take the shackles off your ankles so you can climb out.”

  Still numb with shock, Mattie nodded. “Okay.”

  Quickly he removed the shackles and tossed them aside. Leaving the handcuffs in place, he took her arm firmly and guided her toward the open door where the female agent was waiting. “Get the prisoner to a safe place and keep an eye on her. Get on the radio and get an ambulance and the local sheriff’s office here ASAP. I’m going to get Sam out in case the van blows.”

  “Roger that.” The female marshal heaved herself through the open door, then leaned down and offered her hand to Mattie. “Come on.”

  Mattie braced her feet on the seat back and let the woman pull her from the van. Cold night air engulfed her as she emerged. She smelled gasoline and smoke. Felt heat from the engine fire. The female marshal pointed to a fallen log several yards away. “Sit down and don’t move. You got that?”

  On shaking legs Mattie stumbled over to the log and sat down hard. She didn’t know if it was from cold or shock, but she couldn’t seem to stop shaking. The van had ended up on its side thirty-five feet down a treacherously steep ravine. The interior lights were out, but a single dim headlight shot a beam through the darkness, exposing a cliff that surely would have killed all onboard had the van gone over.

  The female marshal tugged her radio from her belt. “This is Bravo Victor Two Niner—”

  A soft thwack! sounded. Startled by the sound, Mattie looked up in time to see the female marshal collapse. Concerned, she rushed to the fallen woman and knelt.

  “Are you all right?” she asked.

  At first she though the marshal had succumbed to some injury sustained in the crash. Panic hit when she found herself looking at a hole the size of a dime in the woman’s forehead.

  “Oh my God.” Mattie staggered back. She looked around, spotted the two male marshals climbing out of the van. “I think she’s been shot!” she cried.

  The two men looked at her. “What are you talking about?”

  Thwack! Thwack! Thwack!

  Both marshals jerked as if an overzealous puppeteer had yanked invisible strings. Something dark and shiny bloomed on one of the men’s jacket. They collapsed and lay still.

  Mattie stared at the fallen men in disbelief. Someone was shooting at them, but she couldn’t fathom who or why. What was going on?

  A light slashed through the darkness at the top of the ravine. Relief swept through her when four men emerged from a black SUV. She was about to call out to them when it struck her that they were speaking in a language she wasn’t familiar with. Who were they? How had they arrived on the scene so quickly?

  Instinct sent her slinking behind the fallen log. From her hiding place, she watched as they started toward the wreckage and the downed U.S. Marshals. Were these men rescuers? Or were they the shooters?

  One of the men stopped at the nearest fallen marshal. “Where is your prisoner?” he asked in a heavily accented voice.

  The marshal groaned. “Help us…”

  “Where is your prisoner?” the man repeated.

  “Got…away,” the marshal groaned.

  The man drew back a booted foot and kicked the marshal. “Where is she!”

  The marshal ground out a curse. “Screw…you.”

  Hissing a word Mattie didn’t understand, the man pulled a gun from his belt. “Stupid American,” he said and shot the marshal at point-blank range.

  Horrified, Mattie scrambled back, put her hand over her mouth to keep herself from screaming. She’d never seen anything so brutal in her life. Who were these men? Why had they shot that marshal in cold blood? And why were they looking for her?

  But deep inside, Mattie knew what they wanted. The knowledge terrified her almost as much as the brutality she’d just witnessed.

  The killer stepped back, his eyes skimming the area, a predator hungry for a kill. Mattie instinctively sank closer to the ground.

  “Check the van!” he shouted to the other three men. “Find the scientist. I want her alive!”

  Knowing she would be discovered within minutes if she didn’t get out of there, she frantically looked around. But there was no place to run. No place to hide. Oh dear God what now?

  The ravine offered her only route of escape. It was steep and rocky and as black as an abyss, but if she wanted to live she was going to have to risk it. Silently she slithered on her belly to the edge of the cliff.

  “There are tracks here!” came a gruff male voice scant yards behind her.

  “Spread out!” came the killer’s voice. “I want her found!”

  Gripping an exposed root, Mattie slid over the ledge. Her feet dangled. She could hear rocks falling below. Saying a silent prayer, she let go of the root and tumbled into space.

  Chapter One

  Sean Cutter knew from experience that good news never came in the dead of night. For an instant he considered not answering his cell phone.

  “Cutter,” he growled.

  “It’s Martin.”

  Uneasy surprise rippled through him at the sound of his former superior’s voice. Martin Wolfe was CIA and at the very top of the agency food chain. At one time the two men had been friends, but that friendship had ended a year ago when Cutter walked away from a career he’d invested twelve years of his life in. A fact that made this call at two o’clock in the morning all the more ominous.

  “Why in the bloody hell are you calling me at this hour?” Cutter snapped. But he’d always known the call would come. He’d known one day they would want him back, that he wouldn’t be able to refuse.

  “The Jaguar is in the country,” Wolfe said.

  The name slammed into Cutter like a fist. For several interminable seconds he couldn’t speak.

  “You there?”

  Shaking himself mentally, Cutter sat up, threw his legs over the side of the bed. “Talk to me.”

  “I got three dead U.S. Marshals and a missing Defense Department scientist. The Jaguar wants the scientist.”

  Cutter got a bad feeling in the pit of his stomach. “Why?”

  “She was the brain behind the EDNA Project.”

  The situation solidified in a terrible rush. The EDNA Project was a top-secret weapons program funded by the Department of Defense. Though his knowledge of the weapon itself was limited, he knew DOD had been developing a new generation of weapons. A technology The Jaguar would do anything to obtain. If he got his hands on the scientist, he would possess a weapon the likes of which mankind had never seen.

  “Martin, I’ve been out of the CIA for two year—”

  “I need you back, Sean. I don’t have to tell you what this son of a bitch is capable of.”

  Cutter knew exactly what The Jaguar was capable of. He had the scars to prove it. And even after two years, he still had the nightmares…

  “If he gets his hands on EDNA, every city in the world will be at risk of being incinerated. We can’t let that happen.”

  Cutter closed his eyes, the gravity of the situation sinking in. “Why me?”

  “Because you know The Jaguar better than anyone. You’ve got the training. The experience.”

  The killer instinct, Cutter thought darkly and felt a little sick. After what happened on his last mission, he’d sworn never again…

  A refusal teetered on his lips, but he didn’t voice it. Sean Cutter might have walked away from his career, but he never walked away from duty. Not even when he knew it could probably kill him.

  “I want you to find the scientist before The Jaguar does, and bring her in.”

  It
seemed a simple assignment on the surface. But Cutter knew there was more. With Martin Wolfe, there was always more. “What else?”

  “I want you to bring The Jaguar in this time, Sean. Homeland Security has given me forty-eight hours to get this done. After that I have to take this public. Bring in local law enforcement and FBI.”

  “And if The Jaguar gets to her before I do?”

  “You have the authority to do whatever it takes to make sure she doesn’t talk.”

  “What are you saying, Martin?”

  “I’m saying she’s expendable. If the situation boils down to her life or the population of Los Angeles or New York or Houston, I want you to take her out.”

  Cutter closed his eyes, dread seeping from every pore like fear sweat.

  “I’ll catch the next flight out.”

  “I’ve got a Lear waiting.”

  “Pretty damn sure of yourself, aren’t you?”

  “No, but I am sure of you.”

  If only you knew, Cutter thought, and disconnected.

  He sat down hard on the bed, dread roiling in his gut. Putting his face in his hands, he tried not to think about what he’d done.

  IN THE PREDAWN DARKNESS, Mattie took the trail at a reckless speed. The cuffs binding her hands hindered, but she didn’t slow down. Her labored breaths echoed against the canyon walls. A cold wind swept through the gorge, whipping the trees into a frenzy.

  She’d been running for what seemed like hours. She didn’t know where she was or where she was going, raw panic driving her forward. All she knew was if she stopped she would die.

  She couldn’t believe her life had come to this. One short year ago she’d been living comfortably in a Washington, D.C., suburb. She’d driven her little blue Jetta to work every morning. She’d been happy. Challenged by her work. And falling for her attractive coworker, Daniel Savage. Everything had come to a grinding halt the day two grim-faced CIA agents walked into her office and arrested her for treason.

  Treason.

  Even now the insanity of the charge still stunned her. Overhead a spear of lightning split the sky. Mattie ducked reflexively but she didn’t slow her pace. She knew it would take a miracle, but if she could reach a phone, she could call Daniel. He would know what to do. He would help her if she asked, even if it meant risking his own reputation to do it. All she had to do was find a house or passing motorist.
