I can't find this book

[Rechan]

Hello, I'm looking for a very specific 3rd party book/PDF. I cannot for the life of me find it or remember its title.

The book/PDF deals with prisons. All the information you would need for running a session in a prison. Escape scenarios, etc. It even had rules for making improvised weapons out of mundane items.

I remember very specifically that the cover was a black-and-white picture of a passage with cells going down the sides.

Can anyone help me out?

Is this it?

It says:
Floor plans and descriptions for a variety of prisons, ranging from an extraplanar cell, to a stone garden filled with petrified prisoners, to a full-fledged mystical fortress.

I don't believe that the book you are looking for is 3e nor specific D&D book. However I did find 2 other books that might be of help for you:

Stronghold Builder

Book of Challenges

I can imagine that there is a D20 book that specifies on jail. If I do find it, I will let you know.
