Answer 1

Books can influence you every time you read them.Mysteries can be solved but i do not know anyone who has travelled through time.
Mystery fictions as we know deal with crimes where an creative clever and extraodinary criminal  cleverly achieve and very odinary but critic detective makes way to the criminal by finding clues.
Science fictions are totally imaginative theories and are probably deal with time travel, cosmos, techology etc. as these are imaginative they facinate much but deal with reality less.
Mysteries always associated with people. Their character their behavior there is total understanding in wrting such mysteries. 
science fictions are associated with 'things' like power to fly in sky or such things which shape the character  of the person in fiction.

science fictions make readers believe in situations which may not happen and mysteries go with the real interactions in the society.
Every fiction is good or bad in it's own way. there are no less people who read Sherlock Holmes as well Frankenstine and invisible man.
