Book Excerpt: 'The Cell'

— -- About 8:45 Michael Wright visited the men's room, located near the elevator bank at the center of the 81st floor of the North Tower. On his way out he ran into a coworker, Arturo Gonzalez, and stopped briefly to chat with him. Suddenly the building shuddered and Wright heard a crash—a screeching, metal-on-metal jolt—and was thrown back against the wall.

The lights blinked and for a moment, the whole building seemed to teeter. Wright waited for the room to settle and adjusted his vision. Everything had changed. The marble facade on the opposite wall was shattered and a huge crack had opened up in the drywall behind. The floor had buckled and Gonzalez was propped up against the broken vanity. The sinks themselves had moved out from the wall. "What the fuck was that?" Wright asked."Holy shit," Gonzalez intoned.

Smoke threaded through the air between them.

They headed out to the hallway, where the devastation was horrendous. Chunks of roof were falling, the facing wall was ripped open and the elevator doors to their right had blown out. The whole building, Wright realized, had shifted on its foundation. Every joining surface was awry; every hinge was twisted or bent. A crater had opened in the floor ahead of him exposing wires, pipes, girders and beams at least ten floors below. Acrid smoke poured out of the elevator shafts.

Wright's instinct was to get the hell out of there, but instead he turned back toward his office to check on his coworkers. As he ran past the elevators, he heard screaming from the ladies' room. The jamb above the door had caved, trapping whoever was inside. Gonzalez and another colleague began kicking down the door.

Wright's 30 or so officemates were pouring out into the hall. Some were calm, others terrified or in tears. He directed them to the stairwell. Flaming chunks of material were falling around them and Wright could smell burning fuel, though he had no idea where it was coming from.

John O'Neill, the World Trade Center's 49-year-old chief of security, dashed out of his South Tower office to assess the situation. A brusque, larger-than-life New York character, O'Neill had spent all but a few days of his professional life at the FBI, the last eight years as one of its top counterterrorism officials. Ironically, he'd retired from the Bureau two weeks before in order to take what friends called a cushy private-sector job, and former colleagues still regarded him as the nation's most knowledgeable counterterrorist. Only the night before, over dinner with friends, he'd expressed a fear that New York was ripe for an attack like the one he now found himself in the midst of. He made a quick damage inspection, placed a call on his cell phone, and then sprinted back inside to help coordinate the rescue effort.

Joe Lhota, Rudy Giuliani's chief of staff, felt the explosion in his office at City Hall almost a half mile from the World Trade Center. He dashed out onto the steps, saw the flames engulfing the tower and called Giuliani at the Peninsula. An aide answered the phone. "Tell the mayor a plane has hit the Trade Center," Lhota said.

Back downtown at One Police Plaza, anxious aides pounded on Bernie Kerik's bathroom door. The 46-year-old bullet-shaped police commissioner had worked out earlier in the vest-pocket gym attached to his office and was taking advantage of a break in his busy schedule to shower and change. He answered the door wearing nothing but a towel, a beardful of shaving cream, and a "this better be good" expression.
