Victorian London comes to life as an intrepid female sleuth wades through a murky world of collectors and criminals to recover a remarkable child. Bridie Devine-flame-haired, pipe-smoking 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 in this age of discovery. Winding her way through the sooty streets of Victorian London, Bridie won't rest until she finds the young girl, even if it means unearthing secrets about her 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 nothing is quite what it seems.
