Sherlock Season 4: 9 Big Questions After 'The Lying Detective' 

5. Where Has She Been?

Speaking of Sherlock perhaps not seeing his sister in a long time: where exactly has she been?

Presuming that Mycroft has knowledge of her - even if Sherlock doesn't - does that mean she was sent/locked away at some point, but has now managed to return/escape?

She's obviously somewhat unhinged, so did Mycroft lock her somewhere for her own good (and those of people she may hurt)? And how exactly is she back now?
