The Last Oracle (Sigma Force 5)

An underground train crossed under the lake from Mine Complex 337 below to Chelyabinsk 88. Whoever labored in the mines must ordinarily exit out the other side.

Monk prayed they would not be expecting visitors at their back door.

He crossed to the rectangle of riveted steel set into the barrier.

“What do we do?” Monk asked. “Knock?”

Konstantin frowned and crossed to the door. He lifted the latch and pushed. The door swung open, unlocked.

Monk fumbled his rifle around and pointed it through the door. “Warn a guy before you do that!” he whispered.

“No one comes here,” Konstantin said. “Too dangerous. So no need for keys. Only sealed to keep bears and wolves away.”

“And the stray tiger,” Monk mumbled.

Konstantin dropped his pack, opened it, and fished out their flashlight. He passed it to Monk, who shouldered his rifle.

Ducking through the door in the main tunnel, Monk pointed his flashlight. Massive wooden beams shored up the passageway as it slanted into the mountain. A set of steel tracks headed into the darkness, extending beyond the reach of the flashlight’s glow. Closer at hand, a pair of ore cars rested on the tracks near the barrier.

Down the way, Monk noted shadowy branching tunnels. He suspected the mountain was honeycombed with shafts and tunnels. No wonder the current miners occasionally wandered up out of the Stygian darkness for a little light, even if it was in the shadow of a poisonous lake.

Monk asked for directions as they headed out. “So where to?”

Konstantin kept silent.

Monk turned to him.

The boy shrugged. “I do not know. All I know is down.”

Monk sighed. Well, that was a direction.

Flashlight in hand, he descended into the darkness.

Savina noted all the smiling faces. Excited chatter spread among the older children, while the younger ones scurried around, trying to dispense nervous energy. They were in direct contrast to the very youngest among them, those under five and too immature for their implants. Those few remained quiet and detached, demonstrating varying levels of untreated autism: sitting silently, staring vacantly, plagued by repetitive gestures.

Four teachers sought to organize their sixty or so charges.

“Stay in your groups!”

The train waited beyond the open blast doors at the back of Chelyabinsk 88. It would be transporting the children for a short pleasure ride. The young ones were occasionally allowed such a luxury, but today the train was on a one-way trip. It would not be returning, coming to a dead stop at the heart of Operation Saturn.

Behind Savina’s shoulders, the old Soviet-era industrial apartments stared down at the children with hollow eyes. The teachers also had the same haunted look despite their bright words.

“Did all of you take your medicine?” a matronly woman called out.

The medicine was a sedative combined with a radiosensitive compound. While excited now, in another hour the children would be drifting into a disassociated slumber. It would ease any anxiety when the charges blew at the far end of the tunnel and initiated Operation Saturn. The first dump of lake water through the heart of the tunnel and its subsequent blast of radiation would transform the radiosensitive compound in the children’s bloodstream into a deadly nerve toxin, killing them instantly.

The group had considered simply euthanizing the children via lethal injection, but such an intimate act of killing strained even the most professional detachment. Plus afterward, all the small limp bodies would have had to been hauled, loaded, and transported to the heart of Operation Saturn. The plan was for the radiation, blasting for weeks as the lake drained, to burn the bodies and denature the DNA beyond examination—that is, if anyone ever dared approach the bodies. The radiation levels in the tunnel would defy penetration for decades.

So in the end, the current plan was deemed efficient, minimally cruel, and offered the children one last bit of joy and frivolity.

Still, Savina stood with her arms behind her back. Her hands were clenched together in a white-knuckled grip, necessary to keep from grabbing children and pulling them from the train.

But she had saved ten.

She had to console herself with this reality.

The ten best.

They remained in the apartment building behind her, where the control station for Operation Saturn was located. Once done here, the ten Omega subjects would be transported to the new facility in Moscow. It was time for the project to climb out of the darkness and into the sun.

It would be her legacy.

But such a rise had a cost.

Bright laughter and merry calls trailed behind the last of the children. They argued over who would get to ride in the open ore cars and who would be in the front or rear cabs. Only a few older voices wondered why they were going without any of the adults, but even these sounded more excited than concerned.

With the last of the children loaded, the train hissed, hydraulic brakes sighed, and with a snap of electricity, it rolled off down the tunnel. Laughter and shouts trailed back to them. A moment later the blast doors slowly sealed over the end of the tunnel, cutting off their happy voices.

The four teachers headed away. No one spoke to anyone. They barely made contact. Except for a thick-waisted matron in an ankle-length apron. As she passed, she lifted a consoling hand toward Savina, then thought better of it and lowered it again.

“You didn’t have to come,” the woman mumbled.

Savina turned away without a word, not trusting her voice.

Yes…Yes, I did.

11:16 A.M.

Pripyat, Ukraine

Gray sat in the back of the limousine. Up front, Rosauro drove, with Luca in the passenger seat. They rocketed past the first checkpoint on their flight out of the city. The Chernobyl Exclusion Zone stretched in a thirty-kilometer radius out from the reactor complex. It had two checkpoints, one at the ten-kilometer mark and one at the thirty.

Gray wanted to be outside that second gate before anyone realized something was amiss at the reactor. It would not take long for the dead bodies to be discovered and for the place to be locked down.

Earlier, as Gray and Kowalski had fled overland back to Pripyat from the site of the ceremony, he had called Rosauro on the walkie-talkie that Masterson had supplied him. She had reported an inability to reach Sigma command. He had instructed her to keep trying. By the time Gray arrived at the hotel, lines of communication with Washington had reopened. Rosauro had commandeered one of the limousines. She had also stolen the driver’s mobile phone.

Gray clutched the phone now, awaiting a call from Director Crowe. Painter had his hands full over in Washington, but at least Mapplethorpe was out of commission and Sasha was safe.
