For those of you who have mentioned liking (or not!) Patricia Cornwell, I have switched over from her to the Kathy Reichs (sp?) books. She is a forensic anthropologist herself, & she writes the same type of books as Cornwell, but I like them much better.
I am also a big fan of Ann Rule. She does a great job of telling true crime stories that are gritty & suspenseful, without being over the top (which seems to happen more with men authors, IMHO, for some weird reason).
Two other mystery suspense authors I like are Faye & Jonathan Kellerman. They are a married couple who both write. Her books are especially interesting, because they feature an Orthodox Jewish husband & wife as the main characters. The husband is a homicide detective. Great books…a lot of detail about their lives as well as the mystery!! (His books do have a gay supporting character, but I have not found ths as blatant an attempt at political correctedness as Cornwell’s).
