The Dark Lantern by Gerri Brightwell (2008)
In late Victorian London, young maid Jane Wilbred comes from the country to take a position with the Bentley family. Soon Jane becomes the pawn of both upstairs and downstairs. Jane’s mistress Mina Bentley has a secret past she is desperate to outrun and a mysterious woman shows up claiming to be the widow of Mr. Bentley’s older brother. Is the young man wooing Jane in love with her, or only using her for his own master’s devious plans? Wonderfully gothic and atmospheric.
