I stayed at the Inn till morning. It doesn't mean that I did nothing.
I went over the file that the mayor had given me about the two missing merchants and their guards. The file included the findings of other teams who failed to find what happened. There was a detailed report on what they did and how they did it.
Hmm, how does the mayor know about this?
There was no way that the investigation teams would voluntarily give their methods to the mayor.
Every person has a certain way of doing things and that way may not be useful in all paths but useful in certain ways of life. These methods would be their way to live a life in this world. No one would give up their livelihood voluntarily.
Either they were forced or there were spies who observed and recorded everything that these investigation teams did.
What's the use of that?
