The sum of all fears - Tom Clancy [296]
"Just the tritium remains," Fromm said, his back to them.
"Yes," Ghosn said, "I can do that myself."
Fromm was about to say that there was one more thing. He let it wait a moment, and didn't pay attention to Abdullah's footsteps. There was no sound at all as the guard removed a silenced pistol from his belt and pointed it at Fromm's head from a range of one meter. Fromm began to turn, to make sure that Ghosn knew about the tritium, but he never made it around. Abdullah had his orders. It was supposed to be merciful, as it had been for the machinists. It was a pity that it had been necessary at all, Qati thought, but it was necessary, and that was that. None of that mattered to Abdullah, who merely followed his orders, squeezing on the trigger smoothly and expertly until the round fired. The bullet entered the back of Fromm's skull, soon thereafter exiting through his forehead. The German dropped in a crumpled mass. Blood fountained out, but sideways, without reaching Abdullah's clothing. The guard waited until the blood flow stopped, then summoned two comrades to carry the body to the waiting truck. He'd be buried with the machinists. That, at least, was fitting, Qati thought. All the experts in the same place.
"A pity," Ghosn observed quietly.
"Yes, but do you really think we would have further use of him?"
Ibrahim shook his head. "No. He would have been a liability. We could not trust him. An infidel and a mercenary. He fulfilled his contract."
"And the device?"
"It will work. I have checked the numbers twenty times. It is far better than anything I might have designed."
"What's this about tritium?"
"In the batteries. I only need to heat them up and bleed off the gas. Then the gas is pumped into the two reservoirs. You know the rest."
Qati grunted. "You have explained it, but I do not know it."
"This part of the job is work for a high-school chemistry lab, no more than that. Simple."
"Why did Fromm leave it for last?"
Ghosn shrugged. "Something has to be last. This is an easy task rather than a hard one. Perhaps that is why. I can do it now if you wish."
"Good."
Qati watched the procedure. One after another, Ghosn loaded the batteries into the furnace, which he set for very low heat. A metal tube and a vacuum pump drew off the gas emitted by each in turn. It took less than an hour.
"Fromm lied to us." Ghosn observed when he was done.
"What?" Qati asked in alarm.
"Commander, there is almost fifteen percent more tritium than he promised. So much the better."
The next step was even simpler. Ghosn carefully checked that each reservoir was air- and pressure-tight - it was the sixth such test; the young engineer had learned from his German teacher - then transferred the tritium gas. The valves were closed and locked shut with cotter pins, so that any vibration in transit could not open them.
"Finished." Ghosn announced. The guards lifted the top of the bombcase and lowered it into place from an overhead winch. It fit precisely into place. Ghosn took an hour to weld it shut. Another test confirmed that the bombcase was pressure-tight. He next attached a Leyboold vacuum pump to the case.
"What exactly do you need to achieve?"
"A millionth of an atmosphere is what we specified."
"Can you do that? Won't it harm-"
Ghosn spoke not unlike Fromm, surprising the both of them. "Commander, please? All that presses in is air. It does not crush you, and it will not crush this steel case, will it? It will take a few hours, and we can also test the integrity of the bombcase again." Which had also been done five times. Even without being welded, the case held well. Now one piece of metal, it would be as perfect as the mission required. "We can get some sleep. It doesn't hurt the pump to run."
"When will it be ready to transport?"
"In the morning. When is the ship leaving?"
"Two days."
"There you have it," Ghosn smiled broadly. "Time to spare."
First,
