From IMDB:

Eliza Scarlet joins forces with a Scotland Yard Inspector to solve crime in 19th century London.

PBS Masterpiece is showing each episode one week at a time. From PBS Passport all 6 episodes can already be streamed. Each episode is about 1.5 hours.

Eliza Scarlet is the daughter of deceased detective Henry. She needs to earn a living and wants to be a detective herself.  She meets resistance to this goal from Scotland Yard Detective William ‘The Duke’ Wellington who was also a friend to Henry.  In each episode she fights to be included in the current investigation and also in each episode she gains a bit more respect from the anti-feminist William. Of course, a romance is in the making. Overriding the 6 episodes is the question: How did Eliza’s father Henry really die?

Involving period piece.  Worth the watch.
