Free murder mystery game?

Hi there,

Last year I created a mystery murder game for my family. Everybody enjoyed it so much (we were 23), that this year I need to do the same. I was very happy to do so, but it is in less than one month and I still haven't really figured out what the plot will be etc. I need help. Anything.

Any cool plot twists or mystery murder games are very welcome in my inbox!

Thanks,
