Former chief warrant officer and amputee Sam Blackman and his partner, Nakayla Robertson, are opening a detective agency. They have high hopes that the thriving mountain region will provide a steady stream of cases. Their first client, a quirky elderly woman in a retirement community, makes a strange request. She wants Sam to right a wrong she committed over seventy years ago. Her victim: F. Scott Fitzgerald. Her crime: stealing a manuscript when Fitzgerald resided in the stately Grove Park Inn. Sam's task seems simple enough: retrieve the woman's lockbox and deliver the manuscript to Fitzgerald's heirs.
