~Rewrite and edit of this story is called Misery Looms.~ Mysterious murders had plagued Central for a couple of weeks and the military doesn't know who was killing people or how. Roy assigned Ed to investigate into the murders, but while doing so Ed gets badly injured. Now, forced to live with Roy, will Ed find out who injured him and why or will it remain a mystery? Will Roy and the rest of the military find out who's been killing all these people or will the answers be lost in the dark? (Parental Roy/Ed, a little bit of Roy/Riza.) Sequel to Fullmetal Vampire is Nightmare.
