Eliza and her rival Patrick Nash have both traveled to France to try to catch a notorious conman. Problem is, they both think they have the right man. Which one is right?

Eliza investigates the disappearance of a magician during his act on behalf of a popular newspaper. But the arrangement puts a wedge between her and William, who doesn't trust the paper and is annoyed by leaks to it from his men. 

Eliza Scarlet of Miss Scarlet and the Duke may be fictional, but she does have a few real-life historical analogues of trailblazing female detectives and forensics experts, including in Chicago. 

Eliza and William confront an imminent major change in their relationship while Eliza tries to find out who tried to kill her rival detective, Patrick Nash, and ends up in danger herself.

Patrick Nash has come to see Eliza as a rival undercutting his business and so wants to hire her by any means necessary. But Eliza refuses, instead competing with Nash to solve a case before him and prove herself. 

William and Moses reluctantly work together when Eliza comes under suspicion of a series of break-ins at the city mortuaries and has to go into hiding. Ivy also helps out Moses, while Eliza finds a new helpful accomplice. 

Eliza is hired to investigate the theft of a sketch by Charles Darwin from a natural history museum, but she eventually discovers that the case is much more of a puzzle than it initially appears.
