Here are two murder mystery kits to get you started. Each one is from a different era and has a different composition of characters. Some of the mysteries have extra characters that you can add in if you like, depending on your guest list.

I [Riley and Bryna Sweeney] wrote these mysteries and freely give you permission to use or change them as you see fit.
