My name is Sarah, and up until last Tuesday, I thought I was living a perfectly normal, comfortably boring life. I have been married to David for five years. We live in a quiet, affluent suburb, have a golden retriever named Buster, and spend our weekends doing yard work or binge-watching true crime documentaries.

Looking back, the irony of that last part makes me sick to my stomach.

It all started on a crisp Tuesday morning. David had been talking about trading in his old SUV for months. It was a bulky, dark gray beast of a car that he’d owned since before we met. He loved that car, but the transmission was finally starting to slip, and the dealership had offered him a fantastic trade-in value. He was scheduled to drop it off on Wednesday.
