For years, a killer stalked the hills around Florence, Italy, preying on young couples making love in their cars. In 2000, thriller writer Douglas Preston moved to the Tuscan hills to write a book. But once he got there, he found anything but sunshine. Instead, Preston got trapped in the strange case surrounding the murders. His book about the saga, The Monster of Florence, is a fantastic read, which I got to review for World Hum this week. But I think also think it’s a fascinating look at what lies beneath the surfaces we travel across.
