When a lobster fisherman discovers a dead body in Scotland's Firth of Forth, DCI Karen Pirie is called into investigate. She quickly discovers that the case will require untangling a complicated web—involving a long-ago disappearance, art forgery, and secret identities—that seems to surround a painter who can mimic anyone from Holbein to Hockney. Meanwhile, a traffic accident leads to the discovery of a skeleton in a suburban garage. Karen has a full plate, and it only gets more stressful as the man responsible for the death of the love of her life is scheduled for release from prison, reopening old wounds just as she was getting back on her feet.
