The noose begins to tighten around Raskolnikov

Ask, and ye shall receive. In yesterday's post I noted that at roughly 1/3 through F Dostoyevski's Crime and Punishment we have yet to meet Raskolnikov's  mother and his sister (Dunya) - R received a letter from his mother noting that she and D were en route to St. Petersburg - and we had lost sight of the Marmelladov (sp?) family, whose daughter, Sonya, will play a major role toward the end of the novel. The next chapter - the last in Part 2 (of ) - introduces or re-introduces all of these characters. R - after his reckless and almost suicidal behavior when he returns to the scene of the crime and draws a great deal of attention to himself (and does he tauntingly say that he committed the murder?; maybe not at that point, though he did say so earlier in his meeting at the Crystal Palace) R spots a commotion in the street and rushes toward it to discover that a drunken man had been trampled by some coach horses; the man turns out to be M., and R sees to it that M is taken to his nearby apartment and that a doctor is called to help. This is another instance of R's benevolent nature and his oblivion regarding money - he offers to pay all the medical expenses, when he can barely spare enough money for food and clothing; the episode becomes particularly striking when the daughter, Sonya, 18 years old, comes to the flat in her "outfit": She's been working the streets as a prostitute. It appears that Her father, M., dies just as she arrives, though FD is a little squirely on that, as we never see the moment of death - perhaps he survives, against all odds (as many people w/ alcoholism seem to do). Leaving the scene, R heads to his own tiny flat, where his mother and sister, just arrived, greet him with tears and embraces (they had not seen one another for 3 years). FD doesn't develop this scene much further in this chapter, but it's obvious that their arrival will provide further torment for R.; how can he possibly tell them that he had killed two women w/ an axe? Yet how can he hide from them his predicament and his overwhelming guilt? Obviously, as the investigation of the murders leads officials to his door, the pressure on R will become unbearable for him; it's clear that then next section will have to introduce the police inspector, w/ his seemingly friendly but actually, for R., quite sinister and threatening, interrogations.
