Charles Lenox is at the pinnacle of his political career and is a delighted new father. His days of regularly investigating the crimes of Victorian London now some years behind him, he plans a trip to his uncle's estate in the expectation of a few calm weeks. When he arrives in the quiet village of Plumley, however, what greets him is a series of strange vandalisms upon the local shops. Only when a far more serious crime is committed does he begin to understand the great stakes of those events.
