At least, I *think* it was a Commodore 64 game, this was years ago and my memory is fuzzy.

Basically you were a person, possibly a detective, who was going around at some kind of party or gathering at what appeared to be a creepy castle. It was either 1800s type or early 1900s maybe, nothing modern or really old.

I know there was a crime of some kind to solve by talking to people and finding clues; it may have been a murder or simply a theft.

I started going through screenshots of C64 games but there are a LOT.
