I came across a reference to a book called Billie Bradley at Three Towers Hall today, so naturally I looked it up. It's part of a Stratemeyer Syndicate series and was written under the name of Janet D. Wheeler. More info here: http://www.series-books.com/billiebradley/billiebradley.html

There are 9 books. At least 5 of them are PD in the US and available at Gutenberg:

I found conflicting information about the years in which some of the volumes were published.

Interesting. Children's mystery books are always fun.
