Have you ever hosted a MURDER MYSTERY PARTY?

My birthday is coming up and I never do anything exciting for it. Especially this year, things are so weird, but I have been wanting to do a murder mystery party for years. I have found a few websites where you can purchase all the necessary items – like the characters and story line mostly, I guess. But there are lots of sites to choose from, and without purchasing yet I am not totally sure how they work. My friends and I all love themed parties, so this is perfect. We want to do a Wild West themed one, which I have seen on several sites, but I just wondered if anyone has any personal experience. I am so stoked on this idea, any input is welcome!

If it matters, I would probably “host” it and not really partake, and it would be a group of ten, not including myself.
