Please take a look at my Substack – www.personsunkown.net – for in-depth features on true crime and non-fiction books on the subject

Why do people commit crimes? How are they caught? Or not caught? These are questions I think we are all interested in to some degree. I'm a journalist and author delving into cases old and recent, as well as a contributor to documentaries such as Murder by the Sea, Voice of a Killer, The Real Prime Suspect and Dark Son: The Hunt for a Serial Killer. I'm currently working on a book about corruption and how the hit BBC drama Line of Duty echoes real-life wrongdoing in the police.
