Quote 13
[Raskolnikov] was hopelessly in debt to his landlady, and was afraid of meeting her. (1.1.2)
Right away, the novel digs into one of our deepest fears: the landlady, or landlord as the case may be. Since it's only been a few years since the serfs were emancipated, and since the serfs were "owned" by people who also owned land, landperson phobia was probably extremely acute in Russia.
Quote 14
"I want to attempt a thing like that and am frightened by these trifles," [Raskolnikov] thought, with an odd smile. (1.1.5)
Of course, Raskolnikov is referring to his murderous idea. Part of what his mixed-up brain wants to do is overstep his fears of the landlady, to reach a place where he is in power, either literally or by becoming fearless.
Quote 15
"On a broken chair stood a candle in a battered copper candlestick." (4.4.4)
This is the first thing Raskolnikov sees when he enters Sonia's home. Notice how both the chair and the candlestick are rather beaten up? Dostoevsky really wants to emphasize Sonia's poor living conditions.
