Soon after Sally Lockhart's father drowns at sea, she receives an anonymous letter. The warning it contains makes a man die of fear at her feet. Determined to discover the truth about her father's death, Sally is plunged into a terrifying mystery in the dark heart of Victorian London, at the centre of which lies a deadly blood-soaked jewel.
An elderly lady loses her money on an investment; a conjuror is pursued by thugs; and a clairvoyant mentions the name of the richest man in Europe and his mysterious company. Seemingly unconnected events set Sally Lockhart on the trail of an evil far more awful than she could ever imagine.
In London in 1881, twenty-four-year-old Sally finds her young daughter and her possessions assailed by an unknown enemy, while a shadowy figure known as the Tzaddik involves her in his plot to defraud and exploit the hordes of Jewish immigrants pouring into the country.
In 1882 sixteen-year-old Becky applies for a tutoring job in London and becomes embroiled in assassination, intrigue, and dangerous politics in the small European kingdom of Razkavia.
