Expansion pack ideas

I'd LOVE a murder mystery pack. I always think of it being placed on a english victorian goth world (maybe the place where the mob that went to Forgotten Hollow originated from?).

Murder Mystery with new career: private detective. Vibe: Noir fiction. Premade Sim: a femme fatale, of course. Build mode: a massive quantity of clutter items. CAS: 1940s fashion.

I would like to see a good castaway pack.
