Imagine this scenario: You are sent an anonymous letter inviting you and your family to a dinner party. Many of your friends and work colleagues are sent the same invites to this dinner party. When you get to the address shown on the invitation, you find that you are at an isolated mansion of a very famous person who you, your family and your friends etc know very well and this person wants to make amends with them for his various wrongdoings to them over the years.
During the dinner party, one of the guests gets killed. Panic and chaos ensues. All of the guests start trying to leave, but they can’t, because the bridge to the mansion, (the mansion is on a tiny island, with a bridge to access the mansion) has been broken in a heavy thunderstorm.
The famous person who invited everyone to the dinner party also gets killed, and nobody can call the emergency services due to the landline not working and no mobile phone signal being available due to the mansion being in such a remote area.
All of the guests search for more clues, and unfortunately, more of the guests get killed, and later on, the killer is caught and in the morning arrested. However, it turns out they were innocent and you find the real killer, and they threaten to kill you, as you might blab about it to everybody else.
How would you feel about the entire thing? Would you end up feeling traumatized for the rest of your life, seeing so many people die, then nearly being killed yourself?
