True crime books on cases similar to The Watcher of Westfield?

Hi, I realise I might be looking for something that doesn't exist, but I figured I'd ask anyway. The true crime happening that interests me the most is the story of The Watcher of Westfield. I've always hoped that an investigative journalist would look back into that case and manage to solve it and write a book about the whole thing, but I know that might never happen.

Does anyone know of any true crime books on cases similar to that one?
