The Return of Sherlock Holmes
All day I turned these facts over in my mind, endeavouring to hit some theory which could reconcile them all, and to find that line of least resistance which my poor friend had declared to be the starting-point of every investigation. (Empty House.1.7)
"I don't think I could have done it in cold blood. It was a hundred times more difficult than getting up. But I had no time to think of the danger [....]" (Empty House.1.33)
"I have a theory that the individual represents in his development the whole procession of his ancestors, and that such a sudden turn to good or evil stands for some strong influence which came into the line of his pedigree. The person becomes, as it were, the epitome of the history of his own family."
"It is surely rather fanciful."
"Well, I don't insist upon it." (Empty House.2.19-21)
