My son lost his house, his company, and most of his time with his children after his ex-wife accused him of being unstable. By the time I found him, he and the twins were living in a car. I did not promise revenge. I said, “Tell me everything, and do not protect anyone.”

The March wind swept across the long-term parking lot at Chicago O’Hare International Airport, carrying that damp, bitter cold that sinks into your bones before you realize how badly you are shivering. The sky was the color of bruised iron, spitting sharp pellets of sleet that stung my cheeks.

I had flown overnight from Seattle because my son, Daniel Foster, was turning thirty-two. I wanted to surprise him before he spent another birthday pretending a quick, hollow phone call from his father was enough. I expected the smell of fresh coffee, the chaotic laughter of a messy household, and my five-year-old twin grandsons tackling my legs before I even made it through the front door.
