This is a favorite series of mine which focuses on Sherlock Holmes' fictional wife Mary Russell. She's super sharp too, of course, and also solves mysteries. They're a great team, and I love her spirit and spunk.
This is a pretty convoluted storyline that involves pirates imitating pirates imitating pirates in a play within a play within a play. It's pretty wild and wooly.
This is a great series for fans of Sherlock Holmes, but I'd recommend you read some Sherlock Holmes before trying this series because it will have more meaning for you if you know some background.
Available at Multnomah County Library. I listened to this on audio.
