Although mischaracterized as unobservant, Dr Watson was an intelligent man who learned from Sherlock Holmes’ methods throughout the many years they worked together. In fact, there is an example of this in DEVI, where Dr Watson applies those methods of observation to keep pace his friend’s deductions:
“Mr. Holmes,” said the vicar in an agitated voice, “the most extraordinary and tragic affair has occurred during the night. It is the most unheard-of business. We can only regard it as a special Providence that you should chance to be here at the time, for in all England you are the one man we need.”
I glared at the intrusive vicar with no very friendly eyes; but Holmes took his pipe from his lips and sat up in his chair like an old hound who hears the view-halloa. He waved his hand to the sofa, and our palpitating visitor with his agitated companion sat side by side upon it. Mr. Mortimer Tregennis was more self-contained than the clergyman, but the twitching of his thin hands and the brightness of his dark eyes showed that they shared a common emotion.
“Shall I speak or you?” he asked of the vicar.
“Well, as you seem to have made the discovery, whatever it may be, and the vicar to have had it second-hand, perhaps you had better do the speaking,” said Holmes.
I glanced at the hastily clad clergyman, with the formally dressed lodger seated beside him, and was amused at the surprise which Holmes’s simple deduction had brought to their faces.
Can you find other moments in the Canon where Dr Watson uses Holmes’ methods of observation?
