No longer fighting gravity to pump blood, Langdon’s heart began to slow. It was a trick swimmers used to re-oxygenate their blood between tightly scheduled races.
On Langdon’s wrist, Mickey Mouse glowed happily as if enjoying the dark: 9:33 P.M. Half an hour until
Opening his mouth wide and tipping back his head, Langdon pulled the deepest breaths he could manage. Each breath burned a little less than the last. His head cleared. He reeled his thoughts in and forced the gears into motion.
He wondered if any of the books in here were stored in heavy, steel, fireproof file cabinets. Langdon had seen them from time to time in other archives but had seen none here. Besides, finding one in the dark could prove time-consuming. Not that he could lift one anyway, particularly in his present state.
Suddenly, Langdon knew.
With a burst of confidence, he jumped to his feet far too fast. Swaying in the fog of a head rush, he reached out in the dark for support. His hand found a stack. Waiting a moment, he forced himself to conserve. He would need all of his strength to do this.
Positioning himself against the book stack like a football player against a training sled, he planted his feet and pushed.
He needed leverage.
Finding the glass wall again, he placed one hand on it to guide him as he raced in the dark toward the far end of the vault. The back wall loomed suddenly, and he collided with it, crushing his shoulder. Cursing, Langdon circled the shelf and grabbed the stack at about eye level. Then, propping one leg on the glass behind him and another on the lower shelves, he started to climb. Books fell around him, fluttering into the darkness. He didn’t care. Instinct for survival had long since overridden archival decorum. He sensed his equilibrium was hampered by the total darkness and closed his eyes, coaxing his brain to ignore visual input. He moved faster now. The air felt leaner the higher he went. He scrambled toward the upper shelves, stepping on books, trying to gain purchase, heaving himself upward. Then, like a rock climber conquering a rock face, Langdon grasped the top shelf. Stretching his legs out behind him, he walked his feet up the glass wall until he was almost horizontal.
With dizzying exertion, he planted his feet against the wall behind him, braced his arms and chest against the stack, and pushed. Nothing happened.
Fighting for air, he repositioned and tried again, extending his legs. Ever so slightly, the stack moved. He pushed again, and the stack rocked forward an inch or so and then back. Langdon took advantage of the motion, inhaling what felt like an oxygenless breath and heaving again. The shelf rocked farther.
Langdon rocked the shelf, extending his legs farther with each push. His quadriceps burned now, and he blocked the pain. The pendulum was in motion.
It only took two.
There was an instant of weightless uncertainty. Then, with a thundering of books sliding off the shelves, Langdon and the shelf were falling forward.
