Cold Impact (Michael Flint #6)

Chapter 1

-

Michael Flint ran in a low crouch across the open field, night vision turning the darkness into a pale green world. The only sound in the Czech countryside at two in the morning was his own breathing.

The field was wide and flat, five hundred yards of open ground stretching north from the farmhouse where he’d spent the last three days watching. The grass was damp with dew. His rubber-soled boots gripped the soft earth without a sound.

A quarter mile to his left, a cluster of buildings sat in the center of the property. Two stories of concrete and glass. Flat roofs.

The kind of buildings designed to bore anyone who happened to notice them. Someone driving past on the road or flying overhead would have no reason to look twice. Which was exactly how the billionaire wanted it. The spectacle was underground, reserved for the guests he chose to invite.

On the south side of the building cluster was a flat lot where several vehicles were parked, all dark. Security cameras were mounted on every corner, sweeping the grounds in slow, overlapping arcs.

Flint’s route took him north across the open field, threading a path between the sight lines he’d mapped over three nights of surveillance. Everything he needed was underground, and his entrance was hidden in the hillside beyond the tree line ahead.

He covered another fifty yards. The tree line was close now, a dark band of oaks and undergrowth rising against the sky. Beyond it, the land sloped upward into a low hillside where the Soviets had built a back exit door they probably thought no one knew about.

Buried sixty feet under the building cluster, a former Soviet nuclear bunker waited. Built in 1984 as a joint project between Moscow and Prague, it was designed to survive a direct nuclear strike and sustain two hundred military personnel for a decade.

Now it belonged to a German financier named Werner Kessler.

“I’m moving to the entrance,” Flint said into his comms.

“You’re still clear. Nobody watching.” Carlos Gaspar replied from Miami, seven time zones away.

Gaspar was a former FBI agent and Army Ranger who never seemed to sleep. “I’ve fed the cameras a recording of the empty field. The guards are seeing what we want them to see. Motion sensors won’t work while you’re out there.”

“How long before Kessler’s guards figure it out?” Flint asked.

“Until someone realizes the timestamp isn’t changing.”

“What about the guard rotation?”

“Same schedule as before,” Gaspar said. “The roving guard started his cycle three minutes ago. He’s on the far south side of the complex. You’re entering through the north side, so you’ve got at least twelve minutes before he works his way back to your end.”

“Okay. Going in.”

Kessler had purchased the property eight years ago and spent tens of millions converting the underground complex into a private estate. Master suite. Guest apartments. Swimming pool. Theater. Library. Hospital. An indoor garden with simulated sunlight.

A billionaire’s fortress buried in the Czech countryside.

The ultra-wealthy had been building places like this for years.

Former missile silos in Kansas converted into luxury condominiums. Decommissioned military bunkers in Germany sold as survival retreats.

Underground complexes in New Zealand designed for Silicon Valley billionaires who feared everything from pandemics to nuclear war.

The builders marketed them as survival shelters, but that was only half the truth.

These places were designed for luxury living.

Swimming pools and wine vaults and private cinemas.

Guest suites and dining rooms built to host parties.

Secret doors and hidden passageways that owners showed off to their friends after dinner like expensive toys.

The bunkers had become status symbols. Proof that you were wealthy enough to buy your way out of the apocalypse, and stylish enough to do it in comfort.

Kessler’s facility was one of the most elaborate in existence. He lived here for months at a time, entertaining guests who felt privileged to be invited into his underground world. He owned many homes, but the bunker was his showpiece.

Flint reached the tree line and dropped to one knee behind a thick oak. He pushed the night vision away and listened. Wind moved through the branches above him. An owl called from somewhere deeper in the trees.

Tonight, Kessler was celebrating his first wedding anniversary with his new wife. A woman forty years younger than him, according to the photographs Gaspar had pulled from social media before she’d scrubbed her accounts clean.

Ten couples had arrived yesterday afternoon for a long weekend of parties. The staff was busy. The guards were managing visitors instead of watching cameras. The kitchen was producing five-course meals. The whole facility was focused on Kessler and his guests and his celebration.

Which was exactly why Flint was here tonight.

Get inside. Get what he came for. Escape without gunfire. That was the plan.

Three weeks of preparation for what he expected to be forty minutes of work.

The party was a perfect distraction. Ten extra couples in a facility that normally ran like a quiet machine.

Twenty extra bodies for the guards to think about.

Twenty reasons for Kessler to be looking somewhere other than his private study.

Flint had been here last night, clearing a path through the undergrowth without leaving obvious signs of disturbance. The cut stems were still fresh. He could smell the green sap in the air, sharp and clean, mixing with the earthy scent of wet soil and decomposing leaves.

He moved through the trees and down the gentle slope on the other side, where the land fell away toward a drainage channel.

The channel, an old concrete infrastructure built before the fall of the Soviet Union, was about four feet wide.

Cracked walls. Moss. Standing water in the bottom.

It carried runoff from the fields into a small creek a hundred and fifty feet downhill.

He followed the channel to where it intersected the hillside. There, recessed deep into the slope and concealed behind a concrete facade designed to look like part of the drainage infrastructure, was a massive steel door. Twenty feet wide and twelve feet tall.

The Soviets had built this exit to handle armored vehicles, not just foot traffic. Two hundred soldiers and their equipment needed to evacuate fast if the main entrance was destroyed. The opening was big enough to drive a tank through.

The escape tunnel.

Standard Soviet military doctrine. Every facility built to withstand a nuclear attack needed a secondary exit capable of full-scale evacuation. This door, disguised as part of the hillside, led to a tunnel running a quarter mile underground to the bunker.

Kessler entered his bunker through the hydraulic ramp on the south side of the buildings. Flint was going in through the back door.

Kessler had renovated the exit door to conceal it further.

The original Soviet blast hatch had been replaced with a modern steel door much smaller than the original.

The rest of the original exit was sealed behind reinforced concrete.

Digital keypad. A small camera lens above it, no bigger than a pencil eraser, feeding video to the security station underground.

Gaspar was handling the cameras in real time, replacing the live feed with a looping video. The guards manning surveillance cameras in the bunker below would see what they always saw. A closed door with nobody near it.

Flint punched in the six-digit code that Gaspar had pulled from the security system.

An unexpected pause followed. One second. Two.

The lock disengaged with a solid clunk that echoed off the concrete walls. The echo faded and the night noises returned to faint wind and softly dripping water in the drainage channel.

He pulled the door open. The steel was heavy, but the hinges were well oiled and the door swung easily.

The air whooshed from inside the tunnel as if a huge fan was pushing it outward. Cool, dry, filtered, and recirculated like breathing in an operating room.

Flint stepped inside and pulled the door closed behind him. The lock re-engaged automatically.

“I’m inside,” he said for Gaspar’s ears only.

“Copy that,” Gaspar replied to confirm the connection.

The long tunnel to the bunker stretched ahead. Emergency lighting strips along the floor cast a pale amber glow on reinforced concrete walls. Steel conduit ran along the ceiling. Rubber matting covered the original concrete floor. His boots were silent on it.

The tunnel was enormous. Twenty feet wide and twelve feet tall, built to move armored vehicles and two hundred soldiers in a hurry.

Flint felt the scale of it as he walked.

One man in a passage designed for military convoys.

His footsteps should have echoed off the concrete walls, but the rubber matting Kessler had laid over the original floor swallowed all sound.

Soviet construction. Built for soldiers in full gear evacuating at a run.

The walls were smooth poured concrete, the kind the Soviets built to last. Here and there, Flint could see the faint impressions left by the wooden building forms. Ghosts of a construction crew that had probably been sworn to secrecy and might well be dead by now.

The amber floor lights created a vanishing point ahead that made the passage look longer than it was. The walls were not close enough to touch on both sides even if he stretched out his arms.

Above him, sixty feet of earth and rock separated the tunnel from the open field he’d crossed to get here. The sky and wind were gone. The world had narrowed to concrete and amber light and the steady forward march of his own boots.

A claustrophobic man would have turned back at the door. Flint kept walking.

“What’s the guard doing?”

Gaspar replied, “Still distracted. Watching football on his phone.”
