New Sims 4 expansion "Murder at the Manor" leaked?

If I recall correctly there was mention of a murder-mystery theme in a survey. Now while I doubt The Sims would add Murder in any of their titles, murder mystery wouldn't be much without, you know, murder. (I'm sure most of us have done the poorly made pufferfish nigiri at a dinner party in our games before, but that hardly counts.) I have my doubts, even though I'm totally down for it.
