Buckingham Palace Gardens by Anne Perry (2008)
Anne Perry researches the Victorian era thoroughly so her stories are historically accurate. The real bonus in this mystery is the plot that encircles the Prince of Wales. It’s a cliff hanger. Perry also introduces a new character, Gracie into the series. Gracie infiltrates the servants’ staff of the Prince and is a source of vital information for special investigator Thomas Pitt. Perry revitalizes the historical mystery.
