How does Elizabeth Marie Pope use imagery in The Perilous Gard?

Imagery:

"The village was so far off the beaten road that she would not have been surprised to find the people shy of outsiders - silent, awkward, suspicious even - but she was entirely unprepared for the sort of fear and hatred that had swept over their faces when they saw her with the little boy."

"It was a child's slipper which had once been fine leather, bright crimson, with a lace at the ankle, exactly like its mate that Christopher had found on the curbstone of the Holy Well - but this one was stained and faded and worn almost to rags."
