Season 4 opens with Eliza having taken over the business of Nash & Sons (not that he has any sons) and things are not going entirely smoothly, although help comes from some familiar sources.

In fact, Eliza teams up with Duke to investigate a burglary in a high-end brothel whose clients include important members of the British government.

Eliza is on the verge of earning life-changing money when she offers to help the heir to an unclaimed fortune. It's a race against time to claim the money and Eliza will need Duke's help, but a revelation about his personal life makes working together impossible.

Eliza is on the trail of a notorious conman and tracks him down to a hotel in a remote part of France. She believes she has finally caught Scotland Yard's most wanted man, but she's not the only hotel guest who wants to claim the reward.

A famous magician does the ultimate disappearing act and vanishes into thin air. All of London is talking about the mystery and Eliza is hired by a newspaper to investigate, despite the fact that Duke is already on the case.

Scotland Yard has its eye on potentially disruptive gangs and political groups. Eliza is hired by The Duke to go undercover and infiltrate one such group.

Eliza is conflicted. Is she a woman or is she a detective?

Eliza steps into her father's shoes and takes over his detective business, following the shocking news of his death.
