The first black garbage bag struck my swimming pool at six seventeen on a Thursday morning.

I heard the splash from my kitchen, where I was making eggs for my eleven-year-old daughter, Lucy.

By the time I reached the sliding glass door, orange peels, coffee grounds, damp newspapers, and broken plastic hangers were spreading across the water.

A woman in a purple raincoat stood beside the fence separating my yard from hers.

Her name was Vivian Sloane, and she had spent the previous two years telling everyone on our street how much she valued cleanliness.

When she saw me watching, she smiled without embarrassment.

“Your pool looks disgusting, Noah,” she called.

“You just threw a bag of trash into it.”

“You cannot prove that.”

I raised my phone, but she was already walking toward her back door.

The backyard camera had recorded the splash, yet a hanging wisteria vine hid the narrow strip of ground beside Vivian’s fence.

I had bought the house in the outskirts of Asheville, North Carolina, because Lucy needed a place where she could feel safe after her mother’s death.

The pool was old, but its shallow end had become the place where my daughter learned to float without being afraid.

I worked as an audio editor for a regional public radio station, and my schedule allowed me to walk Lucy to school most mornings.

I also knew how to recognize a carefully staged sound.

The splash that morning had arrived just as a delivery truck rattled down the street, covering the scrape of the fence latch.

I spent forty minutes skimming refuse before Lucy came downstairs wearing her school sweatshirt.

She stopped at the door and looked outside.

“Did the wind do that again?”

I hated the word again.

During the previous three weeks, I had discovered flattened cereal boxes in the filter basket, used paper cups drifting beneath the diving board, and a torn plastic shopping bag wrapped around the ladder.

Vivian had insisted that raccoons dragged garbage from unsecured bins.

The neighborhood had accepted that explanation because Vivian was always the person organizing cleanup days.

This time she had been standing beside the fence with an empty garbage bag in her hand.

“No,” I told Lucy.

“Someone did it on purpose.”

Lucy glanced toward Vivian’s yard.

“Is she mad because I yelled at the people in her house?”

I turned to her.

“What people?”

She pulled her sleeves over her hands.
