Sherlock John pre/post war story

[nebbyjen.livejournal.com]

What I recall (and would love to read again) is a story where I believe Sherlock and John meet while still in school. Sherlock is intrigued but nothing much becomes of the pair and eventually John leaves to join the military.  Sherlock has Mycroft keep tabs on John and when the soldier returns home Sherlock is the only one at the pier waiting for John.  He offers John a ride in his carriage (?) and takes him back to Mycroft's to recover from his injuries. Over time their friendship grows to the point that eventually John agrees to move to Baker Street with Sherlock. I believe this is a long story.

Not certain which 'verse' this story would register in but I don't believe it's BBC. Thank you in advance.
