Rows of first-year students sit at long tables, some taking notes, others staring blankly at the projected images of 18th-century court dress. The lights are dimmed for the slides.

It’s a student. Impeccably dressed in a tailored, black wool blazer over a simple grey turtleneck, dark trousers, and boots that make no sound on the polished concrete floor.

Professor Moreau does not pause her lecture. She doesn’t even glance toward the door.

The student moves with quiet purpose down the side aisle, toward a large, wheeled rack laden with rolls of fabric—muslins, silks, heavy wools—that stands against the wall near the front.
