What to expect

The new novel from the author of Art in the Blood. December 1889. Fresh from debunking a “ghostly” hound in Dartmoor, Sherlock Holmes has returned to London, only to find himself the target of a deadly vendetta.

A beautiful client arrives with a tale of ghosts, kidnapping and dynamite on a whisky estate in Scotland, but brother Mycroft trumps all with an urgent assignment in the South of France.

On the fabled Riviera, Holmes and Watson encounter treachery, explosions, rival French Detective Jean Vidocq… and a terrible discovery. This propels the duo northward to the snowy highlands. There, in a “haunted” castle and among the copper dinosaurs of a great whisky distillery, they and their young client face mortal danger, and Holmes realizes all three cases have blended into a single, deadly conundrum.

In order to solve the mystery, the ultimate rational thinker must confront a ghost from his own past. But Sherlock Holmes does not believe in ghosts…or does he?

Critics Review

‘Haunting, vivid and beautifully plotted, Unquiet Spirits is both an elegant tribute and a cunning update of everything we love about Sherlock Holmes and his world. Bonnie MacBird has done it again!’—Daniel Stashower, Edgar, Agatha, and Anthony award winning author of Teller of Tales: The Life of Arthur Conan Doyle
‘If the original 60 Holmes stories aren't enough for you, read Bonnie MacBird's Unquiet Spirits for another dram of the Great Detective. MacBird deftly blends a series of grisly murders and dark secrets from Holmes’s past into a strong brew!’—Leslie S. Klinger, editor of The New Annotated Sherlock Holmes
‘A superb Sherlockian adventure. Bonnie MacBird’s take on Holmes and Watson is inventive and true to the canon, a splendid blend of fast-paced action and detection in a deliciously gothic Highland setting. I can’t wait for her next book.’—Dana Cameron, BSI, Agatha, Anthony, and Macavity award-winning author of the Emma Fielding mysteries
‘Pour yourself a wee dram, toss another peat on the fire, and prepare to be swept up in the great detective's Highland fling. MacBird's spooky, scholarly, thoroughly ‘spirited’ follow up to Art in the Blood is a triumph of voice, place, and plotting. Highly recommended for fans of Sherlock, Scotland, and whisky lovers everywhere.’—Catriona McPherson, bestselling author of the multi-award-winning Dandy Gilver series
