the waters of babylon

I'm not sure what chapter you are referring to but the narrator is initially afraid,

at first, I was afraid. When my father went into the house to search for the metal, I stood by the door and my heart felt small and weak. It was a dead man's house, a spirit house. It did not have the smell of man, though there were old bones in a corner. But it is not fitting that a priest's son should show fear. I looked at the bones in the shadow and kept my voice still.
