Two days before an auction of the contents of High Gates House in Borrowdale, Christopher Henderson bumps into Jennifer Reade, the heir to the entire estate, and the expected recipient of the proceeds of the house clearance sale. She discovers a dead man in the cellar of the house but threatens and cajoles Christopher into remaining silent about it until after the auction to avoid complications and delays.

The auction begins but is soon halted by the police with the news that a murder has been committed. Simmy, Christopher's wife and amateur sleuth, applies herself to the mystery of the deaths but not everyone is as they appear and Simmy will have to contend with a ruthless and determined killer in her fight for the truth.
