Nanny!john genfic
Hi all. I'm looking for a fic where John was Sherlock and Mycroft's nanny when they were growing up (NOT the Ain't No Sunshine series). Sherlock is now an adult and at a crime scene when he gets a call and abruptly leaves. When Lestrade protests, Sherlock replies something along the lines of "My father is dying." He's referring to John, who by now is an old man.
