The second novel in the series «Twelve Victorian Detectives». Interest in wartime treasures connected to the Spanish inheritance flares up anew almost two hundred years later. The owner of an invaluable casket is robbed and brutally murdered. Investigating the crime, Inspector Knight seeks advice from retired judge Sir William Crawford. The judge’s niece, Patricia, doesn’t want to stand aside—almost leading to tragic consequences. The plot is based on real events from the history of Soviet criminal investigation, but the action is moved to Great Britain of the Victorian era—and to Sherlock Holmes. Real historical figures appear in the narrative, but the events they are involved in are fictional.
