EPTEMBER 7, 10:07 A.M.

SOUTHERN URAL MOUNTAINS

As the sun shone on a crisp morning, Monk crunched along the gravel road that wound through the ghost town. Weeds and bushes grew waist high, making it feel as if they were wading through green water. Konstantin kept abreast of him, while Pyotr and Kiska trailed. Marta followed, too, but she was drowned away in the green sea, parting the grasses as she maneuvered through them.

“There’s little coal in the mountains here,” Konstantin lectured around a bone-cracking yawn. “All the mining in the region is for metal or metallic ores.”

Monk knew the kid was wired between exhaustion and terror. The tall boy spoke quietly to keep himself awake and to combat anxiety.

“Cobalt, nickel, tungsten, vanadium, bauxite, platinum…”

Monk let him prattle as he kept a watch on the town to either side. The buildings looked hastily constructed, made of clapboard with elevated plank sidewalks that bordered the road. They passed a one-room schoolhouse with intact windows and still lined with wooden desks inside. A couple of old trucks, Soviet-era green, sat rusted into the roadbed. The only brick building had Cyrillic lettering along the facade. Monk could not read it, but it appeared from the shelves inside to be a general store and post office. Next to it stood a saloon with dusty bottles still on the shelves.

It was as if one day the townspeople had simply stepped out of their respective doors and left without ever looking back.

Monk did not have to guess why. From this higher vantage point, Lake Karachay spread wide, rimmed by muddy banks and reflecting the sunlight in a sparkling lie that hid its toxic heart. Monk glanced to the badge hanging from his pack. The red hue had grown to a darker crimson. He checked it every few minutes.

Konstantin noted his attention. “We must stay no longer than another hour. It is very dangerous here. We must get underground soon.”

Monk nodded and stared up. The entrance to the mine lay another mile above them. He could make out the steel outbuildings and skeletal derricks that framed a larger structure hugging against the mountain. Two large metal wheels flanked the central building, tailing wheels, used to dredge up debris from the diggings below. The gravel underfoot probably came from that mine.

Monk set a faster pace.

Ahead, the only other substantial structure appeared as the road swung a hard switchback to climb another level up the mountainside. The mill rose three stories high, the tallest building here. It was built of logs with a tin roof. Its wooden waterwheel, green with moss and lichen, had broken off its moorings and lay toppled across the creek. An old flood must have torn it free.

As they headed toward it, Kiska cried out.

Monk swung around and saw Pyotr standing stock still, as upright as a pole, his eyes huge, bright with terror.

Monk’s chest clenched.

No…not here.

Marta loped a circle around the boy, also sensing his distress. Like Monk, she didn’t know where the danger lay or from where it might strike—but they both knew what the boy sensed.

Monk flashed back to the tiger charging at him, one ear gnarled.

Zakhar.

The beast shouldn’t have been able to track them, not across all that open water. But tigers were strong swimmers. The hunter must have forded the swamp and waited to ambush its prey here. Monk did not doubt such cunning from Zakhar.

Monk searched the tall grasses, the jumble of buildings. The creature could be hiding anywhere. The hairs along Monk’s arms prickled, almost sensing the feral eyes upon him. They were out in the open, exposed. And without a single weapon. They’d lost their only dagger when Marta had attacked Arkady.

“Back,” Monk said, pointing to the brick building. “Move slowly. Toward the store.”

Despite all the windows, it would make the stoutest stronghold. They might find something they could use for defense among its shelves. Monk pulled Pyotr to his side. The boy quaked under him. As a tight group, they retreated along the path they’d forged through the grass.

Monk kept an eye behind him, mostly because Pyotr did the same. He trusted the boy’s intuition. Where the road curved toward the mining station, the mill house towered across the creek. Monk knew tigers often sought the highest ground: a tall boulder, a lofty tree branch, a mountain ledge, someplace where they could leap upon their prey.

As if sensing it had been discovered, a shadowy striped shape slid like a flow of oil from one of the upper-story windows near the back of the mill. If Monk hadn’t been concentrating, he would’ve missed it. The tiger vanished into the tall grasses.

“Run,” he urged Konstantin and Kiska.

Monk pulled Pyotr up into his arms with one tug.

The two children ahead of him shot forward, stung by terror and fueled by adrenaline. Monk followed, with Marta racing beside him.

Behind Monk, a heavy crack of board sounded as something heavy bounded off the waterwheel and across the creek. The general store’s door was open, only thirty yards away. It would be close. He prayed for a walk-in freezer, somewhere they could barricade.

The crack of a rifle split through his terror.

Gravel exploded with a bright spark at his toes.

Monk dove to the side, rolling through the high grass, cradling and cushioning Pyotr with his own body. He kept rolling until he ended up behind one of the rusted hulks of an old truck.

The sniper had shot from the lower half of the street.

It had to be one of the Russian soldiers.

Turning, Monk spotted Konstantin and Kiska leaping like frightened deer across the planked sidewalk and through the open door of the store. Marta followed them with one bound. One of the windows shattered as a rifle shot echoed. But the trio had made it inside safely.

Monk sheltered behind the truck and hunkered down. He could not reach the store without crossing open ground.

He glanced up the street.

There was no sign of the tiger. Not a blade of grass moved. No rasp of gravel under heavy paw. The sudden shot must have dropped Zakhar low, startling the cat as much as them. It lay hidden out there.

Monk crouched, trapped between the tiger and a sniper. But that was not the only danger. Another hazard smothered over them all. Beyond the town’s edge, Lake Karachay shone brightly, radiating outward with its toxic pall. Even standing still here was death.

12:30 A.M.

WASHINGTON, D.C.

As an alarm klaxon continued to sound, Yuri stood alongside Sasha’s bed, shielding her with his body from McBride. The child had snugged into her sheets, hands over her ears, hypersensitive to the bells and shouts. Across the bed, Kat Bryant went to Sasha, consoling her with a palm atop her head. Behind the woman stood the pathologist Malcolm Jennings and a guard.

Yuri faced McBride. The man crouched a few steps away, his back to the corner of the room, his hand twisted in the blond braid of his hostage, Dr. Lisa Cummings. He held his cell phone pistol against her neck.

They were at an impasse.

And Mapplethorpe was already pounding his way down here with commandos. Yuri’s blood burned with the thought of the bastard getting his oily hands on Sasha. He could not let that happen.

Yuri shifted to the stainless-steel instrument table and picked up a syringe from among the vials of drugs used to treat Sasha.

“Yuri!” McBride snapped at him with warning.

He answered in Russian, knowing McBride understood. “I will not let you have Sasha,” he said and stabbed the needle into her intravenous line.

As he pushed the plunger, he saw McBride shift his gun away from his hostage and toward him. The syringe just contained saline, a ruse. Yuri whipped around and flew straight at the man. At the same time, Lisa stamped her heel on the man’s instep and smashed her head back into his face.

The pistol fired, explosive in the small space.

Struck in the shoulder, Yuri spun half a step. He barely noted the pain. He crashed into McBride, knocking Lisa out of his grip. Yuri slashed at McBride’s throat and jammed the second syringe he had palmed off the instrument table, popping into the jugular. The syringe contained a non-diluted concentration of Sasha’s medications. At full strength, it was a toxic pharmacology of chemotherapeutics, epinephrine, and steroids.

Tangled together, McBride emptied his clip into Yuri’s stomach. Muffled by his body, it sounded like loud claps and felt as if someone were punching him in the gut. Still, Yuri slammed the plunger home, sending the poisonous slurry straight for the heart.

McBride screamed.

Yuri fell with the man to the floor. He knew what McBride was feeling: flames shooting through his veins, pressure detonating in his head, heart squeezing with agony. Hands pulled Yuri off McBride and rolled him to the floor. He spotted Kat draped over Sasha, protecting her from the gunfire, keeping the child’s head turned away.

At his side, McBride writhed up into a convulsive seizure, spittle flying, turning bloody as he bit through his tongue. The body would live, but not his mind. The drugs would burn through his brain, leaving him a hollowed husk.

Lisa leaned over Yuri. “Help me!”

More hands appeared, applying pressure to his belly. Blood spread across the floor. Kat joined him, cradling his head. He coughed. More blood. He reached a hand, knowing she would help.

“Sasha…,” he gasped out.

“We’ll protect her,” Kat said.

He shook his head. He knew this already, did not doubt her heart. “More…more rebyonka.”

He had trouble focusing—mind and vision. The world darkened, and the pain sank into coldness.

He tried to speak, to tell her where. “Chela…insk…” His hand scrabbled to the floor, drew two numbers in his own blood: 88.

Her hand closed over his. “Hold on, Yuri.”

He wished he could, for Sasha, for all of them.

Darkness clouded over; voices drifted away down a long tunnel. He offered the only thing he could with his last breath.

Hope.

He clenched Kat’s hand and forced out one final message.

“He’s alive…”

Stunned, Kat sat with Yuri’s head in her lap. Had she heard him correctly? She stared down into his open eyes, now lifeless and glassy. He had been frantic at the end, as if seeking some last penance, even slipping into Russian. Fluent in the language from her former days with Naval Intelligence, Kat had understood some of it,

More rebyonka.

More children.

Like Sasha.

She stared at the girl in the bed, now guarded by Malcolm.

Yuri had babbled after that, tried to write something, but it was garbled nonsense. But what about what he’d said at the very end?

Kat turned to Lisa.

Her friend knelt in a pool of the man’s blood. “He saved my life,” she mumbled and placed a hand on Yuri’s chest. Busy with her ministrations, Lisa had not heard his last words.

Beyond Lisa, McBride’s body had stopped convulsing. His eyes were open, staring, just as lifeless and glassy, but his chest rose and fell.

Kat sat, unable to stand, her gaze focusing back to Sasha, to the pile of drawings.

Yuri’s words filled her world.

He’s alive.

His fingers had clamped onto her hand.

A message for her alone.

She knew whom he meant, but that was impossible.

Still, his last words loosened something inside her, stoked what had never fully gone cold. Her breathing grew heavier. With each breath, the fire grew stronger inside her, burning away doubt, blazing light into the dark places in her heart. A part of her dreaded to let go of that darkness; there was security in the shadows. But she refused to staunch these new flames.

Instead, the fire propelled her to her feet.

She grabbed the guard’s abandoned gun from the floor. Straightening, she spoke in a rush to the entire room. “It’s not secure here. We’ll strike for an exit…if not, we’ll find someplace we can fortify.”

As Lisa unhooked the girl’s I.V. line, Kat spotted the coloring book, still open on the bedside table, scribbled in green crayon, a man on a raft.

Impossible, but Kat knew it to be true.

Monk…

He’s alive.

10:20 A.M.

Southern Ural Mountains

The American should be dead.

Borsakov cursed his missed shot. He lay flat in the shadow of a mining shack. The rifle stretched out in front of him, his cheek resting against the stock of his weapon.

He had not expected the sudden bolt of his targets—straight back toward him. It had required repositioning and firing before being fully set. Plus he suspected his sights were incrementally out of alignment after the abuse in the swamp. He had not been able to test-fire the weapon and calibrate its sights. The shots would have warned the targets of his approach.

Still, he had them all pinned down.

Two children and the chimpanzee hid in the brick building. The American and the boy behind the truck. Borsakov slid backward, keeping to the grasses. All he had to do was cross the street, and he’d have the American within his sight line again.

This time he would not miss.

He moved stealthily and low across the road, keeping to shadows for as long as possible. He reached the far side and crouched behind an overturned barrel. He leaned out, ready with his rifle.

Down the street, he had a clear view behind the truck now.

Borsakov’s fingers clenched on his rifle in fury and confusion.

No one was there.

The American and the boy had vanished.

Pyotr huddled inside the truck, curled in the footwell. Monk had lifted him and shoved him through the half-open window, then disappeared between the two buildings behind the truck. Before he left, he had motioned Pyotr to remain low and duck far into the space in front of the seat. Leaves and beetles shared his hiding place. He clutched his arms around his knees.

Somewhere in the dark places in his mind, where he feared to look, he remembered hiding like this: cramped, breathless, hunted. Another life. Not his. Stone had encased him then, rather than rusty steel.

Hovering between then and now, he felt the pinpricks of lights out in the darkness. Stars in the night sky. If he stared long enough, they would grow brighter, falling toward him. But the night sky had always scared him. So he shied away, back to the moment.

As he did so, a hunger filled him. But like the memory before, this appetite did not belong to him. Close by, a large heart thundered, swallowing Pyotr’s feeble beat. Strange odors swelled through his senses: wet grass, the whispers of hot blood in the air, the feel of gravel underfoot. A breath drew heavily, much larger than his own small chest. The scent of the hunt fired through him.

Then another musk came with it.

A new scent.

Another hunter in their midsts.

But this scent carried more than pungent odor.

Memory of searing agony came with it.

Spine prickling, fury burned away hunger.

As Pyotr huddled tighter, that large heart stalked forward, padding toward him.

Monk fled along the rear of the roadside buildings and headed toward the lower half of the street. His back and chest burned, scratched and impaled by splinters from the narrow squeeze between the two clapboard shops. He had secured Pyotr in the truck, safe from the tiger for the moment—but not from the sniper. His first priority was to lure the soldier away from the children, to get him chasing after Monk into the mix of buildings below.

Survival and outwitting the soldier would have to follow that.

Monk ran low. He stuck close to the buildings and avoided piles of dry leaves and foundation gravel. He moved silently until he reached where the lower switchback cut downward. Rounding the last building, he edged back to the main street. Had he gone far enough?

Holding his breath, he peeked around the corner and scanned up the street. He spotted the brickwork of the general store, the rusted truck, and the roadway of weeds and high grass. Nothing moved. A breeze flowed down the mountain and feathered the tips of the grass blades.

But there was no sign of the sniper.

He had to be out there, possibly sneaking up on the children. Monk could not risk a hostage situation if the sniper grabbed one of the kids. Monk bunched his legs under him. He had to dash across the street and down to the lower level of the ramshackle town. The crunch of gravel would make plenty of noise.

But he had to be convincing to draw off the soldier.

Taking a deep breath, Monk burst out of hiding and pounded across the gravel. “Run!” he yelled and waved an arm to imaginary children. “Just keep running!”

Let the sniper think that all the children were with—

—crack—

Fire impaled Monk’s thigh. His left leg went out from under him.

He landed hard, his arms out to protect him. Gravel tore skin from his palm and stumped wrist. He let momentum roll him farther down the street. A second rifle blast ripped through the grass over his head with a sharp whistle.

Monk dropped flat, but he spied through the grass and saw the soldier rise. He had been hiding farther up the street, about halfway toward the brick store. Rifle on his shoulder, he sidled straight at Monk.

The soldier had anticipated his adversary circling to the rear. He had hidden in wait, ready to ambush.

But the soldier wasn’t the only one hunting.

Fifty yards up the street, a parted V of grass swept straight toward the soldier, like a torpedo through water.

Borsakov kept his face stoic, but a dark satisfaction rang through him. He had the man down, immobile, defenseless. He would end this here, make the American pay for the deaths of his comrades on the boat, make him suffer: a bullet through the kneecap, perhaps another through his shoulder.

As Borsakov took another step, a shift of gravel sounded behind him, a whisper of grass blades, rushing like the wind.

Not the wind.

He knew.

Borsakov twisted around. He started firing before he’d even secured his stance. He squeezed hard, rifle chugging with automatic fire in a wide swath. A feral scream of rage ripped through the blasts as Zakhar burst out of the grass and leaped straight at him: legs wide, black claws bared, muzzle curled back from curved yellow fangs.

Borsakov fired and fired. Blood burst in sprays from the striped fur—but he knew there was no stopping the monster.

It was fury and pain, revenge and hunger, lust and determination.

In the face of such horror, a scream burst from Borsakov’s throat, guttural and raw, a primal cry of terror.

Then the tiger landed and pounded him to the ground.

Monk shifted higher, watching the tiger savage the soldier’s body. It reminded him of the bear ripping into the massive wolves yesterday. Monk heard the moist crack of bone, and the man’s scream cut off. The soldier’s body was shaken like a rag doll, gripped by the neck, blood fountaining.

Monk had seen enough and bounded straight at the tiger, his left leg on fire, dripping with blood.

The soldier’s weapon had been flung from his body as he was smashed under the eight hundred pounds of feral muscle and claw. The rifle landed halfway between the tiger and Monk. They would not survive this monster without it.

A growl spat toward him.

Zakhar’s eyes fixed on Monk. In that black regard, Monk knew the cat recognized him, the murderer of his brother. The tiger crouched atop the broken Russian’s body, muscles rippling, hackles high, fur sticking straight out in all directions. Blood flowed across the tiger’s chest and flanks, blurring stripes. The cat survived on pure fury.

Reaching the weapon, Monk slid on his knees and scooped up the rifle. One-handed, Monk struggled with the weapon, tangling with its strap and fumbling to bring it up and find the trigger.

He would never make it in time.

Zakhar’s rear legs bunched for the kill—

—when a second feline scream echoed down the street. It was not as loud, but it rang out in a perfect yowl of fury and grief. Monk recognized it, having heard it just hours ago.

The death cry of Arkady, brother of Zakhar.

Recognizing it, too, Zakhar leaped up, twisted in midair, and landed in a crouch, tail high. A hiss flowed from the giant cat, less fury, more wary confusion.

Monk lifted the rifle and aimed for the metal cap screwed over the back of the skull. He drew a fix just below it.

Steps away, Zakhar’s feral hiss escalated into a whine of pain, of grief, looking for his lost brother.

Firming his stance, Monk squeezed the trigger.

The rifle kicked with a sharp retort.

The tiger jerked, then dropped flat into the grass.

Monk sank to his side, leaning on his stump. He shouldered the rifle. He knew his aim had been true, a merciful kill shot through the base of the skull. He checked his own wound. The soldier’s bullet had ripped a gash in his thigh, but it had passed clean through.

He’d live.

Monk took several breaths, then forced himself to rise.

From down the street, Konstantin and Kiska appeared. Monk knew he owed his life to little Kiska and her perfect pitch and mimicry. Heard once, she had emulated Arkady’s cry, amplified by the rolled sheet of tin Konstantin now tossed aside into the grass.

Marta bounded out of the store and straight for the truck.

They would collect Pyotr and move on. Limping, Monk studied the mine complex above the town. They still had a hard climb, but Monk had something to do here first. He hobbled over to Zakhar and placed a hand on the tiger’s bloody shoulder, wishing the beast the peace it had never known during its life here.

“Go on now, big fella…go join your brother.”

12:43 A.M.

WASHINGTON, D.C.

Painter raced down the empty hallway toward the stairs. Alarms rang, accompanied by the Protocol Alpha siren. Evacuation of the facility was almost complete. The emergency exits emptied into a neighboring underground parking garage. Painter did not doubt that Mapplethorpe had men guarding those exits, making sure the child didn’t escape. But at least the base personnel should be out of the underground cement bunker.

All except those caught during the initial attack.

After setting the fail-safe, Painter had stopped first at the communication nest of central command and had tapped into the video feed. He’d found that outside communication had been cut off, indicating someone had the schematics to the command structure, but they’d left internal lines open. From the top floor’s cameras, he watched Mapplethorpe’s commandos gather a dozen hostages, their wrists secured behind their backs with plastic ties.

It could’ve been worse. At this late hour, Sigma had been lightly staffed. Satisfied, Painter had prepared what he’d needed, and once done, he turned his attention to the danger closest to his heart. He shoved open the door to the stairwell and almost knocked Kat Bryant on her rear end.

She carried Sasha in her arms.

He struggled to comprehend.

Beyond Kat, he spotted Malcolm Jennings and a security guard.

“What? How?” he stammered out.

Lisa shoved past Malcolm and hurried up to him. She was covered in blood. His heart hammered, but she seemed uninjured. She wrapped her arms around him and gave him a fast hug. He felt the shudder of her relief, matched by his own—then they parted, professional again.

“What happened?” he asked.

Kat related in terse, dispassionate thumbnails, finishing with, “We’re attempting to evacuate.”

“You’ll never make it out with Sasha,” he said. “All the exits are surely covered.”

“Then what do we do?” Lisa asked.

Painter checked his watch. “Well, by escaping on your own, you’ve already made my life easier.” He pointed back down. “Take Sasha to the gym locker room. Secure her in there. All of you.”

“What about you?” Kat asked.

He kissed Lisa on the cheek, turned toward the door, and headed out. “I’ve got one last thing to do—then I’ll join you.”

“Be careful,” Lisa said.

Kat called back to him. “Director! Monk’s still alive!”

Painter halted, glanced behind him, but the stairwell door slammed shut. What? He had no time to inquire what she had meant. It would have to wait. He sprinted back down the hall and returned to where he had started, back to the communication nest. Slowing, he tested the air. A sweetness permeated the space, as it should all of central command.

It was the first stage of the fail-safe program: feeding a gaseous accelerant into the air. It took a minimum of fifteen minutes to reach critical levels. And while it was safe to breathe for at least a couple of hours, they didn’t have that long. In another ten minutes, the fail-safe would ignite sparks throughout the base and trigger a firestorm across all levels of central command. The flash fire would last only a few seconds, fed by the accelerant in the air, searing every surface within the concrete bunker. Then sprinklers would kick in, dousing the flames immediately.

Inside the communication nest, Painter checked the row of monitors, receiving video feed from cameras on every level.

He stalked along them until he found the one he was looking for. It showed Mapplethorpe standing beside Sean McKnight. He held a pistol to Sean’s back. Behind them, commandos began disappearing down an open stairwell door.

Painter tapped on the audio from the camera.

“—madness,” Sean said. “You can’t circumvent channels like this. Do you think you can perform an unsanctioned assault upon another agency, then try to clean it up afterward?”

“I’ve done it before,” Mapplethorpe growled. “It’s all a matter of producing the results to match the offense.”

“In other words, the ends justify the means,” Sean scoffed. “You’ll never get away with it. Two people are dead.”

“Is that all? Like I said, I’ve done this many times before. Abroad and here.”

Painter cut into the conversation. He spoke into a microphone that broadcast through speakers on that floor. “Mapplethorpe!”

The man jolted, but he kept his pistol steady. He searched around, then found the camera on the wall. He regained his composure, his lips settling into a sneer of derision. “Ah, Director, so you haven’t evacuated with the rest of your people. Very good. Then let us end this quickly. Bring up the girl, and no one else needs to get hurt.”

Painter spoke into the microphone. “We’ve already taken out your man, Mapplethorpe, and hidden the girl where you won’t find her.”

“Is that so?” Mapplethorpe sniffed a bit at the air. “I see you’ve activated Sigma’s fail-safe program.”

Painter felt a chill. The man had obtained more than just their base schematics; he’d tapped deep into their protocols. Sean had warned him about Mapplethorpe. The bastard had his fingers everywhere, a black spider dancing in the intelligence web. His oily and bland demeanor hid a much more dangerous core.

“And I believe you’ve set the timer for zero one hundred,” Mapplethorpe said, confirming the depths of his intel. “We’ve been unable to decrypt the code to stop it, but something tells me we won’t have to. Not with my holding twenty hostages above. Twenty of your men and women. With families and lives beyond these walls. I don’t think you’ve got the brass balls to let them die, to be slain by your own hand. Whereas I—”

Mapplethorpe lifted his gun to the back of Sean’s head.

“—have no such qualms.”

The man fired. The pistol blast overloaded the speakers, turning into a digital pop and squawk. Sean fell to his knees, then to the floor.

Painter’s chest tightened, unable to take a breath. Disbelief rang through him. A part of him expected Sean to stand back up, to shake off the attack. But just as quickly, a flame as hot as the coming firestorm burned through Painter. Stunned at the man’s brutality and callousness, Painter could form no words.

Unlike his adversary.

Mapplethorpe’s voice returned. “We’re coming for that girl, Director. And no one is going to stop us.”
