It’s 1924, and Ginger Kelly has fled south to safety in the company of disgraced Prohibition agent Oliver Anson Marshall and her newly orphaned young sister, Patsy. But then Marshall is reinstated to the agency with suspicious haste and put to work patrolling for rumrunners on the high seas, from which he promptly disappears. Gin hurries north to rescue him, only to be trapped in an agonizing moral quandary by Marshall’s desperate mother. It’s 1998, and Ella Dommerich has finally settled into her new life in Greenwich Village, inside the same apartment where a certain redheaded flapper lived long ago. Ella is eager to piece together the history of the mysterious Gin Kelly, whose only physical trace is a series of rare vintage photograph cards for which she modeled before she disappeared.
