Autumn, 1897. As fog and unrest descend on London, a renowned Kensington spiritualist delivers an extraordinary message: the ghost of a murdered man has appealed to Sherlock Holmes for justice.



Holmes dismisses the séance as nonsense-until a body bearing the dead man's distinctive scar is pulled from the Thames.. As London grows ever more unsettled, only the razor-sharp minds of Mrs Hudson and her resourceful assistant Flotsam can separate superstition from murder - and expose the killer before another victim is claimed.



Martin Davies is the author of twelve novels, including international bestseller The Conjuror's Bird which was a Richard and Judy Book Club selection and Havana Sleeping which was shortlisted for an Historical Dagger award by the Crime Writers' Association. The Holmes & Hudson series was begun when Martin was at a loss for a suitable birthday gift for his father, an inspired teller of stories, who first introduced him to the household on Baker Street.
