Fics like Brother Mine, Brother Yours

John Watson has kept a lot of things from Sherlock Holmes—his army days, his nightmares, and, oh yes, the tiny little detail that he has a half-brother. When his brother shows up in London and crashes a crime scene, Lestrade nearly faints, Anderson chokes, Donovan swears, and Sherlock discovers there’s something in the world he didn’t already know. Cue sibling chaos, deduction duels, and one very sulky consulting detective. Or: John has two geniuses in his life now, and he’s having far too much fun watching them drive each other mad.
