Publisher's Summary

Holmes and Watson face treachery and danger in this full-length thriller by Bonnie MacBird, author of the bestselling Sherlock Holmes novel Art in the Blood.

Murder, jealousy, and deceit underscore three interlocking mysteries as Holmes and Watson take on a high-profile case at Windsor Castle, a boy drowned in the Serpentine, and a crusading women’s rights activist who suspects a traitor in her organisation. The cases send them into danger into locales as varied as the palace itself, a dockland cannery, an arts and crafts atelier, and a gypsy encampment. But is there peril underfoot as well – right at 221B Baker Street?

The twisting, breathlessly plotted conjoined mysteries that Bonnie MacBird is known for provide a thrill ride that will delight Sherlockians worldwide.
