The year is 1878, and Sally Lockhart (Billie Piper, Mansfield Park) has started her own financial consulting business. When her client, Miss Walsh, loses a fortune from the unexpected collapse of the Anglo-Baltic shipping line, Sally is determined to find out why so many of their ships have mysteriously vanished without trace. Hoping to recover her client’s money, she turns for help to her friends, Frederick (JJ Feild, Northanger Abbey) and Jim, who have started up their own detective agency.

While pursuing their enquiries into the disappearance of the steamship Ingrid Linde, the three sleuths find themselves investigating stage magician Alistair MacKinnon who is being threatened by mysterious thugs, and a psychic medium who seems to be tapping into shady business secrets – all of which draws them unwittingly into a dark and sinister plot fuelled by the dealings of the cruel and heartless industrialist Axel Bellmann, whose business is built on a horrifying secret.
