Watson: Holmes you are a paradox!

Holmes: I have no doubt of it. But what particular convolution of my nature did you have in mind today?

Watson: How then to explain your double nature, Holmes, so organized and yet so haphazard?

Holmes: Hardly a puzzle there. I am organized when I need to be organized. When the games's afoot. When the stakes are high. When a puzzle stands before me. I know the necessity of it.
