I never thought my sixtieth birthday would begin with a private investigator’s phone number in my hand and a thermos full of questions.

My name is Dorothy Whitfield, and I am fifty-nine years old.

Six years ago, I stood in a little chapel in Charleston, South Carolina, and married a man named Nathaniel Brooks. He was twenty-eight. I was fifty-three. Thirty-one years between us, but when he looked at me, I felt like a girl again.

We met at a gentle yoga class held in a sun-drenched studio on King Street. I had just retired from teaching literature at a small college, and my body was betraying me after my husband Richard passed. My back ached from grief. My heart felt hollow. Nathaniel was one of the instructors—tall, with sandy hair and the kindest brown eyes. He moved through the room with a quiet strength that made you feel safe.
