I went down the narrow hall and pushed Sadie’s bedroom door open another foot.

She was sitting on the edge of her twin bed with her laptop on her knees, the bright screen lighting up her face in the dim afternoon.

The crisp twenty-dollar bill lay flat on her wooden nightstand, right next to her reading lamp.

“Look at these, Mom,” she said, turning the laptop toward me as I came into the room.

On the screen were open-toed silver heels with thin crisscross straps and little rhinestones set into the metal buckles.
