As the title says. I eventually want to run an impostor scenario/murder mystery in my World of Darkness game at some point, and would like some pointers.
I wrote an article with my thoughts on running mysteries here:

Concerning decoupling clues from locations, though, that only sometimes makes sense. It’s commonplace for a piece of evidence to only be meaningful in a particular context, and sometimes that context is the location in which it’s found.
That being said, if you can’t move a clue, it becomes more important to make sure there are multiple ways to learn about it. Maybe if the PCs don’t see the muddy footprint in the garden, the gardener did.
Whatever you do, don’t mix up who the killer is behind the scenes just because the player guessed it correctly before you wanted them to.
