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

A Murder Mystery is one of my most favorite things, and if they did this it would be interesting to see how, as I too love Agatha Christie and Clue. Even if it ended up being true and amazing I won't buy anything else until bugs are fixed, there are just so many issues and I'm not going to add more into my game until they truly gix it, if they really do.
