Family Plot: Another John Pickett Mystery (John Pickett Mysteries #3)

In disgrace—again!—with her aristocratic in-laws, recently widowed Lady Fieldhurst is exiled to Scotland with her three young nephews in tow. On impulse, she and the boys decide to stay at an isolated seaside inn under an assumed name, where they can enjoy a holiday far away from the scandal that still plagues the family.
But trouble soon finds them when the boys discover an unconscious woman on the beach—a woman who bears a startling resemblance to the local laird’s daughter, missing and presumed dead for the last fifteen years. Uncertain whether to welcome her as a returning prodigal or denounce her as a fraud, Angus Kirkbride sends to London for a Bow Street Runner.
Meanwhile John Pickett, hopelessly pining for Lady Fieldhurst, resolves to forget her by marrying another. When magistrate Patrick Colquhoun receives Kirkbride’s summons, he packs Pickett off to Scotland before he most junior Runner can do anything rash.
When Agnus Kirkbride dies only hours after announcing his intention to change his will in his daughter’s favor, John Pickett and Lady Fieldhurst must join forces to discover the truth about a family reunion suddenly turned deadly.
