Former Chief Warrant Officer Sam Blackman, a disabled veteran, is opening a detective agency with his partner Nakayla Robertson. 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. Nothing is simple for Sam. The lockbox is sealed with a swastika, a symbol his client insists predates the Nazis and reflects a scene from The Great Gatsby. But when a security guard is killed and the lockbox disappears, Sam realizes this case is more than he bargained for.
