Best logic is not relly describable, it's more the linkags of what are normally dis-associated facts together to come to a conclusion that makes sense.
Example:  
  Human: It's snowing; Sherlock Bear is downstairs in the glove box of the car, someone should go down and get him.
  Benedict: Why? Sherlock is not cold.
  Human: It's snowing, there is no heating in a parked car.
  Benedict: Golves keep human hands warm, when they are inside the glove;
    Sherlock is inside the Glove Box;
    So glove box will keep Sherlock warm;
    There is no need go and get Sherlock now.
