Over the years I have come across dozens of women authors of crime, detective-mystery, and suspense on the internet and I confess to having read very few of them. Below are the covers of seven paperbacks written by female writers who, I assume, were (and are) noted for their craft. I didn't know about them, let alone read their books. I just happened to find them online. Looking up 20th century authors is a pastime. Have you read their books?
