Death Wave

“Don’t worry. We just need to get him to the infirmary.”

Dean felt someone standing beside him, leaning over him, felt a cold hand touch the side of his face, then probe for a pulse at his throat. He opened his eyes, looking up into the startled face of a Russian soldier, then snapped his arm straight up, shoving the tip of the pen directly into the man’s solar plexus.

The applicator was based on emergency medical injector units — the kind used to autoinject massive jolts of atropine in case of an attack by nerve gas. When the tip hit the man’s shirt, the needle fired, sending a dose of a powerful relaxant into his central torso. He opened his mouth to yell … but no sound came out, and his knees were already buckling. Dean rolled out from beneath him as Akulinin grabbed him from behind, clamping his mouth shut and lowering the sagging body to the ground.

The neurosuppressive cocktail in that pen would keep the man unconscious for at least six hours. As soon as he was down, Akulinin stepped around the corner and waved at the other guard. “It’s okay! The son of a bitch is just drunk! Come give us a hand, will you?”

A moment later, the second guard rounded the corner of the shed, his weapon slung. He barely had time to register the fact that the body on the ground was that of the other guard before Akulinin’s arm swept around from the side and slammed the tip of another auto-injector into his chest. The second guard collapsed as swiftly and as silently as the first.

Dean used a small lockpick set to open the simple padlock on its hasp securing the tool shed door. They dragged the Russian soldiers inside, relieved them of weapons, ammunition pouches, and IDs, and left them with their hands and feet bound in plastic zip-strips. Somebody would find them when they finally woke up and started yelling, if not before.

The front door to the control tower facility was unlocked — a somewhat worrisome fact. It suggested that there might be an officer of the watch who made periodic rounds inside the building as well as outside. Since they didn’t know his schedule, they would have to work fast.

They’d brought a small leather satchel with them, another present from the embassy. Dean pulled out a small device the size of a paperback book and scanned the door carefully, searching for live wires and circuits hidden in the wood or bricks — an indication that there might be silent alarms or hidden cameras. “Nothing,” he whispered.

Akulinin pulled a small black cylinder from the bag and planted it in the dirt next to the door. “Okay,” Vic Klein’s voice told them through their implant communicators. “Good picture. Go ahead.”

Inside, the building was completely dark. They didn’t have IR or starlight gear, but the two operators used tiny lights to find their way down a long hall and left, to a suite of back offices, the lights red-hued to preserve their night vision. A search through airport staffing records indicated that Vasilyev’s office was number 12; a search of architectural records in Dushanbe had pinpointed number 12 at the end of the dogleg to the left. The door was locked. Another electronic scan showed an absence of hidden alarms. Dean pulled out a slender rectangle of steel the size of a credit card and slid it between the door and the jamb, popping the bolt.

The office had two rooms, an outer room for a secretary and reception, an inner sanctum for the boss. They performed yet another electronic sweep with negative results. Akulinin left a micro camera positioned where it could watch the door, then checked with the Art Room to make sure the device was transmitting. Next the two operatives picked the lock to the inner door and entered Vasilyev’s private office.

They left the lights off, unwilling to let them show through the closed blinds at the back of the room and make someone suspicious. Using their red minilights, though, they found Vasilyev’s desk, then swept the entire room for electronic signatures. Against the wall in one corner was a four-foot steel safe. Akulinin sat down at the computer and powered it up. Dean moved to the safe.

The safe had been imported from the United States — with a Sargent and Greenleaf Model R6730 locking mechanism — and had been identified as such already in the architectural plans uncovered by Desk Three’s long- distance computer snooping.

The lock mechanisms for safes rated for holding classified DoD documents back in the United States were now required to be electronic, using a keypad to punch in the combination. Though more secure against safecrackers employing traditional methods — listening to tumblers fall through stethoscopes or manipulating the lock — electronic locks were actually easier to penetrate using modern computer technology.

This kind of lock was tougher to get past. A three-number combination lock like this one theoretically had 100³, or one million, possible combinations, though minor imperfections and inefficiencies in the way the numbers lined up on the dial and the way the tumblers worked together in practice reduced that number to roughly 283,000 possible distinct combinations. There were several ways of quickly circumventing such a purely mechanical system, but the NSA operatives didn’t have a high-speed hardened tungsten-carbide drill, a thermal lance, or a plastic-explosives shaped charge, and they didn’t want to make that much noise and call down base security on their heads.

The CIA resident at the U.S. Embassy had sent along something better.

Called a sonic cracker, the battery-powered device fitted around the safe’s dial, the back fitting closely against the surface of the safe’s steel door. Dean pressed a button and felt the unit vibrate. It operated by sending a subsonic pulse through the steel and the lock mechanism and listening for echoed returns, a form of sonar that worked through steel and brass instead of water or air. A green LED light winked on at the top of the device. Signal return received.

He rotated the dial ten to the right and pressed the button again. He continued the process, turning the dial farther and farther to the right until he’d finished a complete circuit. Then he repeated the process, turning to the left.

Behind him, he heard Akulinin mutter as Vasilyev’s desktop came up. “Vista crap, tee-em,” he said. “Are we trying to make other countries mad at us by exporting this stuff to them?”

“As long as the back door is there,” Dean murmured. He was beginning the third set of combination setups now, as the computer chip inside the cracker stored more and more sonic images of the interior of the lock.

“Let’s keep the chatter down,” Rubens’ voice said over their link. “Just in case you missed a passive recorder.”

A passive recorder was an electronic device that could monitor a room, switching on only when there were sounds to be heard — like conversation. The NSA used such devices frequently, utilizing ordinary telephones as the pickups.

Vasilyev wasn’t likely to have that kind of technology at his disposal, but it was simply good field operations discipline to keep the conversation to a minimum. The fact that numerous software packages distributed globally had undocumented back doors allowing interested parties like the NSA to peek at password-protected information, such as the movement of large amounts of money through different banking systems, was something the Agency wanted to keep very secret for as long as possible.

Dean mentally kicked himself on that one — and Akulinin should have known better than to say more than an absolute minimum. That was the sort of mistake that could kill you in this business.

He wondered if Ilya’s judgment had been compromised by the woman.

Had his?

He also wondered what Rubens was doing up and in the Art Room. Last he’d heard, the Old Man had been asleep.

Abruptly, a second LED flashed green. The flashing indicated that the chip inside the unit was processing all of the data.

“I’ve got something here,” Akulinin whispered. He plugged a small device into one of the computer’s USB ports, then typed on the Cyrillic-alphabet keyboard. “Transmitting,” he said after hitting the RETURN key.

“Receiving,” Klein said over their implants. “How are you doing, Charlie?”

“Working,” he replied. There was no telling how long this part of the process would take. The computer inside the cracker was small but extremely powerful, a product of the NSA’s computer research labs, where the joke had it that they were developing both hardware and software that were at least fifteen years ahead of anything yet on the market. By analyzing the patterns of reflected sound waves, it was building up a picture of the wheel-and-gate mechanism behind the safe’s external dial, looking for irregularities and imperfections that would sharply reduce the number of possible combinations. A skilled safecracker could do this with a good ear and sensitive fingers, as well as an expert knowledge of a safe’s internal mechanism, a process known in the trade as manipulation. The sonic returns in the cracker should be able to play through all possible permutations of the wheels inside and come up
