Guardian of Lies

TWENTY-ONE

Anyone familiar with such things might have been skeptical, but Nitikin knew that regardless of the passage of time, more than forty years, the device itself was virtually pristine.

The reason for this was the manner in which it was stored. Soviet physicists had long known that the greatest threat of deterioration to a gun-type nuclear device would be from oxidation and corrosion of the metal parts, and degradation of weapons-grade uranium if it were subjected to oxygen and hydrogen in the atmosphere for long periods.

Corrosion resulted from the close proximity of highly enriched uranium and ferrous metals, in this case tungsten carbide steel. Separate the uranium from the steel, and store each of them properly, in the case of uranium in a vacuum-sealed container, avoiding moisture and humidity, and the shelf life for a weapon of this kind would be extended geometrically, almost indefinitely.

The two subcritical elements of uranium, the projectile and the four concentric rings of the target, had been machined to precision and stored in their separate sealed lead-contained vaults while the weapon was still in the Soviet Union, before it had ever been shipped to Cuba. They had never been removed.

Nitikin had never even seen them, but he knew they were there from the periodic Geiger readings he took through the test vents in each of the lead cases. From these readings he knew that the two separated elements of weapons-grade uranium, the target and the projectile, neither of which alone possessed critical mass sufficient to cause a chain reaction, would, when combined under pressure at the proper velocity down the gun barrel, result in a massive chain-reaction detonation.

If it worked properly, the entire sequence, from detonation of the cordite initiator launching the uranium bullet down the barrel, to the flash of light hotter and more brilliant than the core of the sun, would take but the barest fraction of a second.

The parts were relatively easy to assemble as long as you had the proper tools, protective gear, and, most important, a deft touch with the tongs needed to position each of the elements while they were bolted or fitted into place.

For Nitikin it was this last part that had become the problem. He had developed a slight palsy in his hands. Over the past few years it had worsened. He knew that he could no longer manipulate the metal tongs either to load the gun with the subcritical uranium projectile or to fasten the uranium target rings to the tungsten carbide tamper at the muzzle end of the barrel.

Nitikin had told no one about this, least of all Alim or any of his cadre. He was afraid of what they might do if they knew, not for himself, but for Maricela, his daughter.

Nitikin, at least in his mind if not his heart, remained the staunch warrior. But he knew that Maricela was afraid, fearful of what was happening. He kept the details from her for her own safety. But she was not stupid. How much she knew, he couldn’t be sure. He told her not to ask any questions and to remain out of sight as much as possible.

She had asked him to leave with her on her last trip, to go back to Costa Rica and to live with her and her children there. For Nitikin it was strange. For the first time in recent memory, he actually wanted to go. But by then it was too late. Alim and his men had arrived with money for the FARC rebels and funds for the cartel in Mexico. Alim knew about the device. Nitikin was trapped.

For himself he did not care. Living and hiding with the bomb had been the purpose of his life for so many years that it no longer mattered. But he loved Maricela and did not want her harmed.

He had stalled for time, hoping Alim would allow her to leave, to go back home to her family. Twice he had asked Alim to permit men from the FARC whom he trusted to see her home safely and twice Alim had put him off. Nitikin had already told Maricela that if they permitted her to go, she was never to return to visit him again, under any circumstance. Though the thought crushed his heart, he would say good-bye to his daughter and never lay eyes on her again in this life. Yakov Nitikin knew he was a dead man. If age did not take him soon, Alim would, the moment his usefulness ended and his knowledge became a burden.
