单选题Every night she listened to her father going around the house, locking the doors and windows. She listened: the back door closed; she could hear the fastener of the kitchen window"s click, and the restless pad of his feet going back to try the front door. It wasn"t only the outside doors he locked; he locked the empty kitchen too. He was looking something out, but obviously it was something capable of entering into his first defenses. He raised his second line all the way up to bed.

She stood with her ear against the wall, a small, dark, angry, immature figure. There was no more to be heard from the other room; but in her inner ear she still heard the footsteps of a property owner, the tap-tap of a hammer, the scrape of a spade, the whistle of radiator steam, a key turning, a bolt pushed home, the little busy sounds of men building barriers. She stood planning.
