Hey there, this seems really interesting. I kinda like the investigators/detectives idea - it could be a mix of people who don't really know each other, like a PI hired by someone who went missing's family, a nosy journalist drawn to the town, a police officer who got sent there because they had a shortage or whatever who starts poking round, a paranormal investigator-type who's just up for a good mystery, or whatever else, and they could all start falling over each other. The mysterious inheritance idea is cool too, and family relationships are always interesting to explore. I guess it depends where you want to take it. I do prefer the detectives/investigators option of the two though as I feel it would allow the most freedom in terms of character creation.
