The Serpent Under

Published on .
Collins Crime Club, 384 pages.
ISBN: 9780008380922


Regular price £9.99 GBP

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.
