With his skills as a forensic genealogist, Morton must untangle the mysterious Ann Fothergill's association with the notorious Aldington Gang and the brutal killing of Quartermaster Richard Morgan. As Morton's research deepens, he begins to suspect that his client's family might have more troublesome and dangerous expectations of his findings.
