Holmes and Watson face treachery and danger in the latest 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 organization. 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.
