A Trixie Belden book…update 3

What's In Your Brain? What's In Your Mind?: Somewhere after this I sensed this was a book, I don’t know the title…

There was a woman in Hyde named Trixie…during the KKK and Black Panther shoot out, she tried to protect herself by getting into a coca cola cooler and got stuck…1965

I suspect it was a barrel during the burning of the Alexandra library and or after that…

I suspect there is some love story in the mix as well…
