Mulberry heads to the nearest door and takes a peek inside, not wanting to enter right away just in case someone is there.
She sees what looks like a desk and a locker on her right. The desk and the shelf above it are full of files stuffed with papers.
On her left there is a sort of file cabinet/table with several items on top. A metal basket, a magnifying lens, and a key.
On the back is what looks to the mare to be a sort of makeshift jail. If he had to guess anyone worth imprisoning was sent off to a proper facility. This was probably at best, a holding cell or a drunk tank.
