Anna Katharine Green 
Circular Study 

An early innovator in the detective fiction genre, author Anna Katharine Green gained acclaim for her careful attention to detail and accuracy. However, as she gained confidence as a writer, she also broke ground in the genre by focusing her attention on the motivation and psyche of both criminals and the detectives that pursued them. The Circular Study highlights both of Green’s talents, offering readers an expertly plotted story and a fascinating glimpse into the mind of a killer.
