My sister-in-law and her kids had been living in our house rent-free for forty days when she casually announced, “We’ll need to stay another month.”

I photographed every envelope where it had fallen, backed up the dining-room camera footage, and took Noah to my neighbor’s house.

Then I called three people: my attorney, the lender’s fraud department, and the postal inspector’s hotline.

Ryan followed me outside.

“You’re overreacting. Dana lost her rental. I was trying to help her start over.”
