I want to make a city adventure as GM, inspired by Sherlock Holmes stories and atmosphere. Therefore a Map or complete setting of a London-like city with a river in the middle would by nice.
I am not so familiar with the Pathfinder Settings, so does someone can tell me a source book or Internet Site, where I can find something fitting my idea, to collect ideas for the setting?
part2 of Carrion Crown (trial of the Beast) has the PCs running around looking for clues and presenting them in court. there are some fights in this part of the adventure, but most of them are not important for the story.
Broken Moon (carrion Crown part 3) has something similar in a hunting lodge.
If you'r just looking for a cool city map, I suggest picking up Cities of Golarion, or start googling the larger cities of golarion to see some sample maps untill you find something that fits your idea
