A town suffers two afflictions: a young girl who goes missing, and a curious homeowner who decides to build a moat.

"Diane Miller didn't watch the news. Diane Miller didn't sleep. She shoveled. She filled a wheelbarrow with dirt and carted it into her garage. She used a thick iron bar to pry around large rocks and roll them to the edge of her property. Her skin darkened under the sun during the day and glinted pale-blue in the moonlight. If we opened the window, we could hear her shovel biting into the ground with regular, crisp barks. We watched her until we started to fall asleep, or grew ashamed at our spying, and went back to bed. We always went to sleep before she stopped."
