small dive planes forward and a clear canopy that the driver pulled down and locked into place once he or she was seated on the vehicle.
The machines were rated to five hundred feet, powered by a lithium-ion battery pack similar to those in modern electric cars and equipped with a pair of grappling claws, headlights, and an internal air/water bladder.
The canopy and much of the body were made from hyperstrong polymers designed to resist the pressure at great depths. Though they’d yet to be tested on a deep dive, Kurt had great faith in them. Joe was the main designer, and Kurt had found all of Joe’s designs to be even stronger than the specs indicated.
After a quick series of checks, he was ready to go. He released the strap holding the speeder in place and then set the flatbed gradient lever at thirty degrees. The hydraulics kicked into gear, and the flatbed began to tilt like the back of a dump truck.
Kurt climbed onto one of the speeders and pressed the switch that closed the hatch. The canopy quickly locked into place, covering Kurt snugly. Straddling the seat with his arms stretched forward and his legs out behind him, Kurt felt like he was on a nautical motorcycle.
The tail end of the flatbed reached the lake, and water came up around the sides of the speeder. Through the canopy Kurt noticed the hue of the water. Pink at the very top but darker red as the light was absorbed.
He wondered for a second just how toxic the mess was. Then he twisted the throttle and drove off the ramp, wondering about the sanity of anyone who would dive into a soup like this.
At first, the speeder cruised a few feet beneath the surface. Then Kurt adjusted the dive lever, and the ballast tank filled with water. Pushing the handlebars forward caused the dive planes to tilt downward, and the speeder began to descend.
Kurt continued forward for twenty seconds or so and then leaned to the left, bringing the unit around in a wide turn. By the time he was eighty feet deep, the water around him looked like red wine. Fifty feet deeper, it was the color of dried blood. Whatever compounds were suspended in it, they filtered out the light very efficiently. But as he dropped lower, Kurt was able to make out the top of the dome.
It was smooth but mottled in appearance, as if some kind of mineral had precipitated out on the curved surface. Perhaps it was calcium or copper or manganese, but, whatever it was, it reflected more light than the surrounding water.
As he finished his pass across the dome, Kurt feathered the throttle and ejected the last of the ballast air. The speeder began to sink again.
Kurt stared into the blackness. The roof of the laboratory structure rested about seventy-five feet below the top of the dome. He hoped its surface would be covered with the same minerals and that he’d spot the roof before he banged into it and let everyone inside know he was there.
“Two hundred and ten,” he said, reading the depth gauge out loud. “Two hundred and twenty.”
He scanned the void around him. Nothing but darkness. It was like he was sinking into a black hole.
“Two hundred and thirty,” he said quietly.
If the gauge was reading correctly, he would hit the lab’s roof in twenty feet or so. Still, he saw nothing.
He pumped a smidgen of air into the bladder like a motorist trying to top off his tires to the perfect pressure. One quick hiss, then another one. The descent slowed.
The depth gauge soon read two hundred and forty feet, and Kurt still saw nothing outside. At two hundred and forty-five, he put a slight bit of pressure on the air switch again. And by two and forty-seven, his nerves gave out.
He jabbed the switch until the speeder reached neutral buoyancy. The descent stopped, and the speeder hung motionless in the dark.
Kurt slid his thumb upward and tapped the light switch. He hit it just hard enough to send some juice through the circuit, but not enough to fully switch it on. The lights flashed dimly and went dark again. In a brief flash, they revealed a world of neon red and the corroded top of the laboratory a mere three feet below him.
“At least I’m in the right place,” he muttered.
If this ungainly construction was indeed a laboratory, there had to be a way in. Toxic water or regular, the safest, most efficient way to build an airlock in a marine environment was to put it underneath the structure.
Kurt risked another flash, got a bearing on the edge of the structure, and went over the side. Dropping downward once again, he began to make out a soft glow around the bottom of the lab: illumination spilling from the airlock.
“Nice of someone to leave a light on for me,” Kurt muttered.
At just that moment, the speeder tilted violently to the right, and a strange metallic twang reverberated through the water.
Kurt knew instantly what had happened. Drifting down, he’d hit one of the guide wires that held the dome and its shaft of pipes in place. The impact had wrenched him to the side and spun him around. Far worse, it sent a vibration through the water like the striking of a gigantic guitar string. The noise reverberated off the walls of the pit and came back at him in a shadowy echo.
Kurt righted the ship and looked around for leaks. The cockpit appeared to be secure. He breathed a sigh of relief and continued on downward, hoping to avoid any more trouble.
“What was that noise?”
The question was posed to Janko by one of his men, who was nervously placing a block of plastic explosives beneath a set of computer servers.
“I’m not sure,” Janko admitted. He’d listened to all kinds of creaks and groans during his time on the station, especially when the techs were testing the dome or drawing power from it, but nothing like the strange reverberation they’d just heard.
“Water has a way of distorting sound,” one of the techs mentioned.
That was true, but Janko was not alone in wondering if the structure was safe. One didn’t need to be a scientist to imagine acids slowly etching their way through the metal walls.
“Who knows what the chemicals in this lake have been doing to our hull all these years,” he said. “Finish setting the explosives. I want to get out of here and blow this thing before it dissolves around us.”
The men seemed to agree. They doubled their labors, and moments later the demolitions expert slid out from under the computer bank. “All set.”
“Good,” Janko said. The explosives would tear apart the circuit boards and memory banks. The fire that followed would melt the remnants to sludge before the water poured in. Even assuming they had the ability and fortitude to recover the remnants from beneath nearly a thousand feet of poisoned water, the high-tech labs of the world’s intelligence agencies would get nothing from what they found.
That meant only one job remained.
He turned around and pointed his rifle at a pair of gagged figures sitting on the floor. One man, one woman. Both with their hands tied behind their backs.
The man was either law enforcement or military. Strong willed, he stared at Janko, almost daring him to shoot them. The woman was softer, pretty, with strawberry blond hair, and fear in her eyes. Janko figured he would shoot her first. Put her out of her misery. He raised the weapon.
“Are you insane?!” the tech shouted.
Janko glared at him.
“We’ve turned the oxygen to full,” the tech explained. “We also opened the acetylene tanks. This whole station is filling with flammable gas. If you pull that trigger, the whole place might go up in flames. You want to kill them, use a knife.”
Janko lowered the rifle and looked back at the captives. Had they realized this? Had they been goading him into destroying himself? It didn’t matter. They would face the painful fate of an explosion and fire on their own in a few minutes.
“Set the timer,” he said. “We’re getting out of here.”
Janko watched as the demolitions man set the timer to 10:00 and pressed INITIATE. The clock ticked over to 09:59 and began winding down. Without glancing back, Janko turned and made his way toward the main ladder. Their submarine awaited.
