In July 2015, Mary Yoder, a healthy 60-year-old chiropractor, went to work as usual. Later that day, she began feeling sick. Within 48 hours, she was dead. At first, her sudden decline seemed like a medical mystery. But investigators soon uncovered evidence of poisoning, launching a murder investigation that divided her family and the community.

What appeared to be a clear path forward quickly grew more complicated.

Saskia Inwood woke up one morning, knowing her life would never be the same. The night before, she learned the unimaginable – that the husband she knew in the light of day was a different person after dark. This season unpacks Saskia’s discovery of her husband’s secret life and her fight to bring him to justice. Along the way, we expose a crime that is just coming to light. This is also a story about the myth of the “perfect victim:” who gets believed, who gets doubted, and why. We follow Saskia as she works to reclaim her body, her voice, and her life.
