LONDON HAD SHERLOCK HOLMES. THE DARK ALLEYS OF EDINBURGH HAD INSPECTOR McLEVY. Halloween 1881, Edinburgh, and the dead are restless. In respectable Edinburgh society, beautiful young American spiritualist, Sophia Adler, is causing a furore with her dramatic seances. But the ghosts of the past seem hell-bent on retribution. Inspector James McLevy finds his investigations distracted by more earthly concerns when Muriel Grierson, an outwardly genteel widow is robbed at home. Her knight in shining armour - one Arthur Conan Doyle, recently graduated from medical school - is keen to learn from such a master of detection as the renowned inspector, but McLevy is less sure that he requires a new acolyte. A vicious murder occurs with evidence of supernatural strength and violence. Treachery revenged from a battle long ago. All roads lead to Sophia Adler and the inspector becomes involved with one of the most dangerous women he has ever encountered.
