In Peter Bowen's The Tumbler, money makes a major difference.
When Metis fiddler Gabriel Du Pré hides artifacts from the Lewis and Clark expedition, money causes murder.
A computer billionaire tries to buy the artifacts, first with gifts and then with money. He finally offers fifty million dollars. And the murders begin.
Du Pré doesn't have the artifacts. Benetsee does.
Du Pré's friend Bart is trying to salvage a wayward niece. She and her boyfriend are gymnasts, tumblers. They teach Du Pré's grandchildren (there are a passel of them) to do tricks on the jungle gym.
The Tumbler is filled with threats, and those threats end in murder. Modern computer-oriented society (which Du Pré despises) comes head to head with what Du Pré calls, "Long time gone."
Two intertwined mysteries make it so that Du Pré has trouble sorting things out.
Along the way, someone attacks and tries to rob Bassman, one of Du Pré musical partners. Between books, Talley, the handicapped accordion player, died of an infection, a testimony to the dynamic nature of these characters. They grow, change, and die.
As always, the music plays a huge part in the story. Also, Metis history echoes through everything Du Pré does. In a sense, he is one of the people's historians with the history preserved, most of all, in the music.
I would have never heard of the Metis were it not for Peter Bowen. Bowen has been a Metis historian for me.
I find these books to be unique. I still have a couple to read to finish the series (in its present form).
