As her senior capstone project, Pippa Fitz-Amobi is determined to find the real killer in a closed, local murder case, but not everyone wants her meddling in the past.

She knew Sal when she was a child, and he was always so kind to her. How could he have been a killer? Now a senior herself, Pip decides to reexamine the closed case for her final project. She discovers a trail of dark secrets that might prove Sal innocent. But someone in Fairview does not want Pip digging around for answers, and her own life might be in danger.
