Bridie Devine--female detective extraordinaire--is confronted with the most baffling puzzle yet: the kidnapping of Christabel Berwick, secret daughter of Sir Edmund Athelstan Berwick, and a peculiar child whose reputed supernatural powers have captured the unwanted attention of collectors trading curiosities in this age of discovery. Winding her way through the labyrinthine, sooty streets of Victorian London, Bridie won't rest until she finds the young girl, even if it means unearthing a past that she'd rather keep buried. Luckily, her search is aided by an enchanting cast of characters, including a seven-foot tall housemaid; a melancholic, tattoo-covered ghost; and an avuncular apothecary. But secrets abound in this foggy underworld where spectacle is king and nothing is quite what it seems.
