For eight years, my husband Corbin warned me about our next-door neighbor Stella, a single mother he called unstable and dangerous. He built a twelve-foot fence between our homes and convinced me it was for our safety. I believed him because he always sounded calm, logical, and protective. When Stella suddenly died, I was the only person at her funeral.

Then her lawyer approached me with a sealed letter containing my name and one warning: the truth inside involved my husband.
