Miss Scarlet and the Duke, The Black Witch Moth

The sister of a missing woman hires Eliza to find her, but the case was already closed by the police - creating new tensions between Eliza and the Duke.

A valuable sketch by the recently deceased Charles Darwin has been stolen, and Eliza is hired by an insurance company to find it.

Eliza is forced into hiding when she is the prime suspect in a series of break-ins at city mortuaries. While the Duke tries to find other suspects, she turns to Moses for help.

Eliza investigates a case of blackmail and finds herself with a new rival - Patrick Nash, owner of a large private detective agency who wants to hire her or crush her agency.

A famous mystery writer is at the centre of Eliza's investigation when a series of murders copy scenes from his books. Meanwhile, the Duke juggles problems at work.

While Eliza and the Duke struggle around the edges of their relationship, private investigator Nash is shot just as Eliza agrees to work with him.
