"The Map"

Day 22

It is a map! Hand-written, clearly labeled San Sibilia, semi-stuck to the inside of the case so I had to be careful prying it out so as not to risk damaging it. I went over every line of it, hoping for a start to help my own work.

And it's odd. It's the San Sibilia I know, yes, but different. Some streets bend in different directions, some squares are in different places...I can't write it off as incompetence, because whoever drew this map was a competent draughtsman and a clear-eyed observer, that much is obvious, so I can only assume the changes were deliberate. But who would do such a thing? And why?
