I have been invisible for ten years.

That is what I told myself each morning as I buttoned up my gray uniform and pinned my hair into a tight, no-nonsense bun. The uniform had my name stitched on the left pocket in simple navy thread: Martha. Just Martha. No last name was necessary. I was part of the scenery at The Beaumont Hotel in Charleston, South Carolina. The sparkling chandeliers, the polished marble floors, the sweet strains of the string quartet that played every evening in the lobby—these things were seen and admired by the wealthy guests who passed through our doors. I was as invisible as the air they breathed.
