How does Pat Barker use imagery in The Eye in the Door?

Imagery:

"A sad smell came from the closet: lavender and sweat, a sad smell. Prior's mother had started her life in service in just such a house as this" (Chapter 1, pg. 12.)

"Everything - the chipped green paint, the scuffed no-color floor, the nailed-down chairs - implied that those who visited criminals were probably criminals themselves" (Chapter 3, pg. 27.)
