>some futuristic detective that never left the house, instead just solved missing persons cases by analyzing details in photograph
Your futuristic detective has the same M.O. as Mycroft Holmes, Sherlock's older and reclusive brother who stayed at home or at his club where no one was allowed to speak (except in a small antechamber and then in no more than a whisper); Holmes the Younger would occasionally visit when he was stumped, or needed some bit of information he hadn't written a monograph on. If I recall correctly, the point was that while Sherlock was all about deductive reasoning (here are all my little clues, what do they add up to), Mycroft was a master of inductive reasoning (here is my thesis, if this thesis is true, here are all the details that must exist _somewhere_).
Tangentially, Mycroft was the full name of the computer that gains sentience in Heinlein's _The Moon is a Harsh Mistress_; very smart, but by nature of being a multi-ton computer system, something of a recluse.
