Manchin backed away and retraced his steps. When he returned to his workroom, the assistant was waiting. “Is everything okay, Professor Manchin?” he asked.

“Oh yes. Just a bit of a stomach bug, I’m afraid. Hope it’s not contagious.” The assistant librarian left immediately, and Manchin hung around all day, digging through materials from the steel drawers and reading old reviews he cared nothing about. Several times he wandered off, poking around, looking, measuring, and memorizing.

Manchin returned three weeks later and he was no longer pretending to be a professor. He was clean shaven, his hair was colored a sandy blond, he wore fake eyeglasses with red frames, and he carried a bogus student card with a photo. If someone asked, which he certainly didn’t expect, his story was that he was a grad student from Iowa. In real life his name was Mark and his occupation, if one could call it that, was professional thievery. High-dollar, world-class, elaborately planned smash-and-grab jobs that specialized in art and rare artifacts that could be sold back to the desperate victims for ransom. His was a gang of five, led by Denny, a former Army Ranger who had turned to crime after being kicked out of the military. So far, Denny had not been caught and had no record; nor did Mark. However, two of the others did. Trey had two convictions and two escapes, his last the year before from a federal prison in Ohio. It was there he’d met Jerry, a petty art thief now on parole. Another art thief, a onetime cellmate serving a long sentence, had first mentioned the Fitzgerald manuscripts to Jerry.

The setup was perfect. There were only five manuscripts, all handwritten, all in one place. And to Princeton they were priceless.

The fifth member of the team preferred to work at home. Ahmed was the hacker, the forger, the creator of all illusions, but he didn’t have the nerve to carry guns and such. He worked from his basement in Buffalo and had never been caught or arrested. He left no trails. His 5 percent would come off the top. The other four would take the rest in equal shares.

By nine o’clock on a Tuesday night, Denny, Mark, and Jerry were inside the Firestone Library posing as grad students and watching the clock. Their fake student IDs had worked perfectly; not a single eyebrow had been raised. Denny found his hiding place in a third-floor women’s restroom. He lifted a panel in the ceiling above the toilet, tossed up his student backpack, and settled in for a few hours of hot and cramped waiting. Mark picked the lock of the main mechanical room on the first level of the basement and waited for alarms. He heard none, nor did Ahmed, who had easily hacked into the university’s security systems. Mark proceeded to dismantle the fuel injectors of the library’s backup electrical generator. Jerry found a spot in a study carrel hidden among rows of stacked tiers holding books that had not been touched in decades.
