A portrait painting is stolen from a London home. Shortly afterwards, the owner, Nat, calls on genealogist Jefferson Tayte for his help. She believes the subject of the painting, a young girl called Jess, is a past relative and wants to learn more about her. The problem is that Nat's research has hit a brick wall—Jess appears to have vanished from the slums of Victorian London soon after the portrait was painted.
When Tayte learns that the theft is connected with a recent murder, he's right to be wary, but solving crimes through genealogical research is what he does best. He quickly becomes intrigued by the girl in the painting and agrees to help. What became of her? Who stole the painting, and why would they kill for it all these years later?
As Tayte and Nat go in search of the answers, can they solve the mystery and bring the murderer to justice? Or will they become the killer's next victims?
