I have always enjoyed reading books about True Crime. I have read all the Ann Rule, John Douglas's Mind Hunter and his other books, Zodiac is one of my all time favorites. I think Zodiax is really the book that started my interest in reading about true crime. I don't keep a lot of the books on my accessible shelves due to space but another title that might be of interest is The Mind of a Monster...I can't think of the author right now.
An interesting book I read a while back is called "The Trials of Maria Barbella" by Idanna Pucci. If not found in True Crime, then look in Women's Studies. It is about the 1895 trial of Maria Barbella who was accused of killing the man who raped her. At the age of 22, she became the first person sentenced to die in the electric chair. This is set in New york, she was Italian and was tried in English, which she didn't speak or understand. I found the story fascinating and well written. It is also a fairly short book so not a huge investment in time. I think I might sit down and read it again.
