Everyone is involved with her in some way, that's the secret that they keep. You choose what that secret is. Could be anything from being romantically involved with her to something like you would see in "Mean Girls". Your more than welcome to talk to me about it through PM if you wish. As for who the murderer is, I have chosen and that person knows who they are. The people on the list are classed as suspects and as you can see they are from all walks of life; from family to classmates to strangers she may have had run ins with.
