At 11:00 a.m., she left with a shopping bag and went to the lobby, where she asked the front desk to keep the maids away from her room because her husband was sleeping. She left the hotel, crossed the street, and stopped at the window of a dress boutique. Bruce walked by and without stopping took the bag. She returned to her hotel room to protect the remaining manuscripts, and also to watch what happened at Gaston’s shop.

Strolling by the fountain in front of the classical church St.-Sulpice, and trying hard to blend in with the other tourists, Bruce burned some clock as he fortified himself for what was ahead. The next few hours would change his life dramatically. If he was walking into a trap, he would be hauled home in chains and sent away for years. But if he pulled it off, he would be a rich man and only Noelle would know it. He walked a few blocks, always circling back and covering his trail. Finally, it was time to begin the delivery.

He entered the bookstore and found Gaston poring over an old atlas, pretending to be busy but watching the street. There were no customers. His clerk had been given the day off. They stepped into his cluttered office in the rear and Bruce removed a cedar box. He opened it then opened the archival box inside, and said, “The first one, This Side of Paradise.” Gaston gingerly touched the top leaf and said, in English, “Looks fine to me.”

Bruce left him there. He opened and closed the front door, glanced up and down the narrow street, and walked away, as nonchalantly as possible. Noelle watched the video from the camera in the Hôtel Proust and saw nothing unusual.

Using a prepaid cell phone, Gaston called a number at the Credit Suisse bank in Geneva and informed his contact that the first delivery had been completed. As instructed by Bruce, the ransom war chest was sitting in a Zurich bank, waiting. As instructed, the first installment was wired to a numbered account at AGL Bank in Zurich, and upon its arrival it was wired to another numbered account in a bank in Luxembourg.

Sitting in front of a laptop in his hotel room, Bruce received an e-mail confirming the two wires.

A black Mercedes stopped in front of Gaston’s and Thomas Kendrick got out. He was in and out in less than a minute and left with the manuscript. He went straight to his office, where Dr. Jeffrey Brown was waiting, along with another Princeton librarian. They opened the boxes and marveled at the prize.

Patience was required, but the waiting was torturous. Bruce changed clothes and went for a long walk. At a sidewalk café on Rue des Écoles in the Latin Quarter, he managed to choke down a salad. Two tables away, Noelle sat down for a coffee. They ignored each other until he left, with a backpack she had placed in a chair. A few minutes after one, he entered Gaston’s again and was surprised to see him chatting with a customer. Bruce eased to the rear and placed the backpack on his office desk. When Gaston managed to slip away, they opened the second cedar box and looked at Fitzgerald’s scrawl. Bruce said, “The Beautiful and Damned. Published in 1922 and perhaps his weakest effort.”
