I was very sorry to read that author Andrew Vachss had passed away. He wrote excellent gritty crime novels and was always interested in protecting children. I saw him speak at the Barnes & Noble store at the Inner Harbor in Baltimore many years ago.
I haven’t read all of his books but certainly recommend him to readers who haven’t tried them. I would start with Strega (1987) which was his second novel featuring Burke, a private investigator.
Sad!
