The Robot Vacuum Reveal

Her vacuum cleaner found out her husband was cheating before she did.

When Nell Ridley hears something rattling around in the Roomba, she pops the bin expecting a dime.

She finds a diamond earring. It isn't hers. No other woman has set foot in that house in months. And the Roomba runs every single day — which means it got under her bed since Tuesday.

When she asks her mother whether Tom seems off lately, Diane Whitlock reaches across the table, takes her hand, and says all the kindest things. You've never grieved your father. You've always been sensitive. Tom's the only one who's shown up. Nell leaves ashamed of herself and buys him a steak on the way home.

Six weeks later she uses the little bathroom off her mother's bedroom. The matching earring is sitting in the ring dish.

Nell doesn't scream. In a town of nine thousand where her mother owns the microphone and her job is a line item on her mother's council budget, saying it out loud only makes her the unstable daughter. So she does what she's done at the community center for nine years.

She sets up the room.

Betrayal and Revenge, small-town, and deeply satisfying. You'll think about that last chapter for a week.
