What signals the beginning of the flashback in the following excerpt from Arthur Conan Doyle's "A Scandal in Bohemia"?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 that a strong emotion in a nature such as his. And yet there was but one woman to him, and that woman was the late Irene Adler, of dubious and questionable memory. I had seen little of Holmes lately. My marriage had drifted us away from each other. My own complete happiness, and the home-centered interests which rise up around the man who first finds himself master of his own establishment, were sufficient to absorb all my attention; while Holmes, who loathed every form of society with his whole Bohemian soul, remained in our lodgings in Baker Street..."
