This is an odd little one-level hold, unfortunately neglected judging by the number of comments. The level doesn't follow a traditional layout; instead, each room has a pair of staircases to two other rooms. The goal is to navigate these choices until one finds the exit, with or without clearing the entire set of rooms.
The rooms themselves are typical JtRH-era: lots of tar and mud clearing, guards, brains, not much in the way of lynchpins. Nothing too complex, which isn't necessarily a bad thing.
