I like this quote from chapter 12,
"Yet this train's whistle! The wails of a lifetime were gathered in it from other nights in other slumbering years; the howl of moon-dreamed dogs, the seep of river-cold winds through January porch screens which stopped the blood, a thousand fire sirens weeping or worse! the outgone shreds of breath, the protests of a billion people dead or dying, not wanting to be dead, their groans, their sighs, burst over the earth!"
THe quote is so textured with dark imagery. It is pretty much layered with ghostly visions of death, dark mystery and doom.
