Key Examples in The Adventure of the Speckled Band
Throughout "The Adventure of the Speckled Band," the reader is presented with the contrasting personalities of Sherlock and Watson. Whereas Sherlock is eccentric and sometimes unpredictable, Watson is level-headed and responsible. Sherlock's deductive abilities are unmatched, while Watson is astounded by the former's discoveries. By positioning Watson as a foil for Sherlock, the story accentuates the latter's extraordinariness.
This becomes evident early in the story, when Sherlock wakes Watson earlier than usual:
...I woke one morning to find Sherlock Holmes standing, fully dressed, by the side of my bed. He was a late riser, as a rule, and as the clock on the mantelpiece showed me that it was only a quarter-past seven, I blinked up at him in some surprise, and perhaps just a little resentment, for I was myself regular in my habits.
