John as A&E doctor
I'm looking for a fic where John practices medicine in the A&E. That's it, that's all I remember about this fic. I'm also interested in fics where John's medical degree gets more use than it generally does in canon. I'm nearly positive I read this fic on ao3. May be Johnlock, probably is, actually. And I think it was on the longer side, over 30k at least. Any help would be appreciated! Thanks!
