Key point 1 of 6
Holmes sees what others only look at
The book opens with A Scandal in Bohemia. A tall masked man says he is a count, but Holmes soon names him as the King of Bohemia. The king fears that a photograph of himself with the singer Irene Adler will ruin his planned marriage.
Before the king speaks, Doyle shows the method. Holmes looks at Watson and tells him that he has gained weight and that his servant has been careless with the boots. Then he asks how many steps lead up from the hall to their room. Watson has climbed them hundreds of times and cannot say, while Holmes knows there are seventeen.
The Red-Headed League shows the same skill on a stranger puzzle. A pawnbroker with flaming red hair wins a place copying out the Encyclopaedia Britannica by hand. Facts are everywhere, but only a trained mind sorts the useful ones from the rest. Try to notice what Holmes notices.
