Stanislas Gosse, a low-paid teacher from a Strasburg engineering school, successfully removed the most valuable treasures from the collection of the Abbey of Sainte Odile over a period of years. He didn’t try selling them. He was just a connoisseur of books.
On May 19, near 7 p.m., Stanislas Gosse drove his CitroÃ«n to Mont Sainte-Odile. He brought ropes, three suitcases, gray plastic bags and a flashlight. Once inside the main courtyard, he headed straight to the second floor of the Sainte-Odile aisle of the guesthouse. He walked down a corridor, opened a door using a key pinched during a previous trip, and found himself in the churchâ€™s bell tower.
He tied the ropes to a wooden beam above a trapdoor in the floor and climbed down into a dark, windowless room of about 10 feet by 10 feet with a short 7-foot ceiling. Through an opening in the wall, he slipped into a second, narrow room. A dim light filtered through cracks in the lower part of a wall. The thief gently slid two wooden panels open, revealing rows of neatly lined up books on two shelves inside a cupboard. He took the books off, then one shelf, before sneaking inside the library. At the library in Strasbourg, he had found what he had been looking for in an article from a local history journal that mentioned a secret passage, unknown to anyone currently working at the abbey, except Dietrich, the janitor. It had probably once been used as a hiding place for the monks or as an ossuary â€” a place to store bones.
Gosse selected a few books, wrapped them in plastic bags, then crawled back inside the cupboard. In the second room, he flipped a wooden crate, climbed on it and hauled the bags through the hatch onto the attic. He climbed up the rope, moved the books to a nearby table to clear the hatch, and climbed back down. He repeated the operation eight times throughout the evening. By the time he was done, more than a hundred books were stacked up in the attic. Around 2 a.m., he stuffed the suitcases with books and left them behind, planning to pick them up later.
