I have just missed this picture.
Molly listens to father play, sometimes, on Tuesday night after she’s gone to bed and the house is quiet and John is out at the pub with Mike. It’s just her and Sherlock, because it’s important that da see his friends and that Molly spends private time with her father (even though mostly they ignore each other, her bent over books and him thoughtful on the couch, it’s a familiar sort of silence and Molly loves it). He never plays when she’s awake on those nights, though other evenings he scrapes out John’s favorite songs and sometimes Molly sings.
Instead he waits until she’s curled up in the middle of her bed in da’s old room, all the lights out and her breathing starting to steady down towards sleep. Molly can tell by the silence downstairs that he is picking up his bow, settling the violin beneath his chin, considering the street below him through the window.
It’s a lullaby that he plays, and Molly never learns the name, and she never mentions it to John.
