Things in Jars, Jess Kidd

In Jess’s third book she introduces us to the formidable Bridie Divine, a flame haired female investigator in nineteenth century London who has been hired to recover the kidnapped daughter of a Baronet. Young Christabel Berwick has strange powers, she can control the tides and see into the mind and pick out thoughts the way a skilled angler lands a trout.
Bridie is assisted by housekeeper Cora - rescued from the circus, Ruby, a deceased boxer with spectacular tattoos and Inspector Rose of Scotland Yard.
The rivers of London are rising from their burial grounds, threatening to turn London into a suburb of Atlantis. To find Christabel Bridie has to revisit her past; one she would prefer stay buried but with a child’s life at stake she will not fail, again.
