"Welcome, Madam!" the shop assistant enthusiastically greeted her.
She didn't respond, but simply smiled at her as she entered the door.
When she entered the shop alongside the four that followed her, the little girl suddenly closed the doors, shutting anyone out who would want to visit the shop after that.
On the woman's side, instead of checking the books on the shelves, she headed straight towards the back door while her four servants guarded the door even from the little girl that had happily welcomed them.
She opened the door without knocking and just walked into the room. Inside the new room, the place looked like an office, but there wasn't anyone inside.
Instead, she walked towards the shelves where she touched a statue on one side of the shelves and the shelves moved.
There was a hidden mechanism there that hid a secret passage on the other side.
