Over the last nineteen years, I've worked on a lot of murders. I can't discuss or disclose the details of any of them, of course, but I remember them all. One thought that has often occurred to me is why those who deal with murder in their professional capacity, such as police officers, crime scene investigators, paramedics, scientists, don't commit more murders.
Perhaps they do and just don't get caught. That's a very frightening thought.
I suppose that it comes down to being able to cope mentally after the deed, rather than the practicalities of planning and carrying out a killing.
How long would you be able to live with yourself if you took another life? I know that I'd almost instantly go insane but I wanted to explore the area of historic murders so I wrote the second in the DC Nina Foster series.
