The Scottish crime writer Val McDermid has sold more than 10 million books around the world. Her latest book is a study of the history and science of forensics; those tiny clues from DNA to specks of pollen that betray where we've been and what we've done while we've been there.
Forensics: The Anatomy of Crime is published by Profile Books and Wellcome Collection.
