The Adventures of Sherlock Holmes

I. A Scandal in Bohemia

To Sherlock Holmes she is always the woman. I have seldom heard him mention her under any other name. In his eyes she eclipses and predominates the whole of her sex. It was not that Holmes changed his costume. His expression, his manner, his very soul seemed to with every fresh part that he . And yet there was but one woman to him, and that woman was the late Irene Adler.

All emotions, and that one particularly, were abhorrent to his cold, precise but admirably balanced mind. He was, I take it, the most perfect reasoning and observing machine that the world has seen, but as a lover he would have placed himself in a false position. He never spoke of the softer passions, save with a gibe and a sneer. They were admirable things for the observer, excellent for drawing the veil from men's motives and actions.

But for the trained reasoner to admit such intrusions into his own delicate and finely adjusted temperament was to introduce a distracting factor which might throw a doubt upon all his mental results. Grit in a sensitive instrument, or a crack in one of his own high-power lenses, would not be more disturbing than a strong emotion in a nature such as his.

Break difficult sentences into manageable parts

Runer maps the main clause, subordinate clauses, phrases, and modifiers. When a sentence trips you up, inspect its structure, then return to the text and read it as a whole.

Remember each meaning in its own context

Words change meaning with context. Runer lets you save your own definition with the original sentence and review each sense separately. Dictionaries and AI can help, but you decide what stays.

When you need help, AI sees the full context

Send the current sentence and the surrounding passage to the AI provider you choose. It can unpack grammar, summarize a paragraph, expand vocabulary, or generate a quiz. It steps in when asked and leaves the final call to you.
