A second agent found the wall panel, threw the switches, and plunged the room into darkness. In unison, all four men reached up and yanked down their night-vision headgear, adjusting the goggles over their eyes. They stood motionless, surveying the reading room, which now materialized in shades of luminescent green inside their goggles.
The scene remained unchanged.
Nobody made a dash for it in the dark.
The fugitives were probably unarmed, and yet the field team entered the room with weapons raised. In the darkness, their firearms projected four menacing rods of laser light. The men washed the beams in all directions, across the floor, up the far walls, into the balconies, probing the darkness. Oftentimes, a mere glimpse of a laser-sighted weapon in a darkened room was enough to induce instant surrender.
Still no movement.
Agent Simkins raised his hand, motioning his team into the space. Silently, the men fanned out. Moving cautiously up the center aisle, Simkins reached up and flipped a switch on his goggles, activating the newest addition to the CIA’s arsenal. Thermal imaging had been around for years, but recent advances in miniaturization, differential sensitivity, and dual-source integration had facilitated a new generation of vision enhancing equipment that gave field agents eyesight that bordered on superhuman.
Thermal-imaging equipment had become so sensitive to heat differentials that it could detect not only a person’s location. but their
He found his answer on the central counter that surrounded the large wooden console in the middle of the room. A ghostly handprint, glowing crimson.
Weapon raised, Simkins moved toward the octagonal cabinet, training his laser sight across the surface. He circled until he saw an opening in the side of the console.
The time for silence was over.
“Thermal signature!” Simkins shouted, pointing at the opening. “Flanks converge!”
His two flanks moved in from opposite sides, effectively surrounding the octagonal console.
Simkins moved toward the opening. Still ten feet away, he could see a light source within. “Light inside the console!” he shouted, hoping the sound of his voice might convince Mr. Bellamy and Mr. Langdon to exit the cabinet with their hands up.
Nothing happened.
As Simkins drew closer to the opening, he could hear an unexpected hum rumbling from within. It sounded like machinery. He paused, trying to imagine what could be making such a noise in such a small space. He inched closer, now hearing voices over the sound of machinery. Then, just as he arrived at the opening, the lights inside went out.
Standing at the threshold, he peered through the opening. What lay beyond was unexpected. The console was less of a cabinet than a raised ceiling over a steep set of stairs that descended into a room below. The agent aimed his weapon down the stairs and began descending. The hum of machinery grew louder with every step.
The room beneath the reading room was a small, industrial-looking space. The hum he heard was indeed machinery, although he was not sure whether it was running because Bellamy and Langdon had activated it, or because it ran around the clock. Either way, it clearly made no difference. The fugitives had left their telltale heat signatures on the room’s lone exit — a heavy steel door whose keypad showed four clear fingerprints glowing on the numbers. Around the door, slivers of glowing orange shone beneath the doorjamb, indicating that lights were illuminated on the other side.
“Blow the door,” Simkins said. “This was their escape route.”
It took eight seconds to insert and detonate a sheet of Key4. When the smoke cleared, the field-team agents found themselves peering into a strange underground world known here as “the stacks.”
