Looking For BBC!Verse Fic With a Murder at Mycroft's Office

[2cbetter2.livejournal.com]

Like the title says I am looking for a BBC verse fic where there's been a murder at Mycroft's office, one that Sherlock is called to but does not come until after John, who he has sent ahead, calls him to tell him that Mycroft was not the victim. I also recall a part where Donovan unwisely got into it with Mycroft, likely over the fact she sees/calls Sherlock "freak" all of the time. Does anyone know what story I am talking about?
