A song, a pressed flower, and the sound of two girls' voices recovered from a burned wooden beam by using a brand-new laser technique to read a charred surface like the grooves of an old 78 rpm record. These are the clues that archaeologist Digger Morgan discovers while working on a routine dig at a Maryland plantation. Who were the girls? When was the fire? The answers all lead to 1920s jazz pioneer Kit Jeffers, whose voice mysteriously appears on Digger's computer and whose existence remains haunted by a singular tragic event.
