When a lobster fisherman on an early morning run pulls in his traps, he finds something he wasn't expecting to catch-a body. Turns out the dead man was the brother of a senior Scottish government official who vanished without a trace, and Detective Chief Inspector Karen Pirie is asked to take over the investigation. At the same time, a woman in the wealthy enclave of Perth is clearing out her sister's home after a fatal road accident and finds a mysterious camper van in the garage containing a skeletonized body. But who is it? And how long has it been there? The two cases will draw Karen into the world of imposters, identity theft, and art forgery.
