Lady Adelaide Compton had prepared herself to say good-bye forever to Detective Inspector Devenand Hunter. It would be a welcome relief not to get mixed up in any more murders. Not to mention become un-haunted by her late and unlamented husband Rupert, whose post-life duty had been dedicated to detection and her protection. Surely he’d performed the necessary number of good deeds to get out of Addie’s fashionably bobbed hair and gain access to Heaven by now. But when Addie’s prim and proper mother Constance, the Dowager Marchioness of Broughton is accused of murdering her secret lover, there can’t be enough ghosts and gentlemen detectives on hand to find the truth. The dead Duke of Rufford appeared to lead a blameless life, but appearances can be deceiving. Unless Addie, Dev and Rupert work together, Constance will hang, and Great War flying ace Rupert will never get his celestial wings.
