I have never employed a private investigator. For the moment I didn't have to. I think the work is interesting but it's a work that if you have a family is difficult, because you don't have a timetable. There is a swedish writer called Henning Mankel, that all his books are about a private investigator called Kurt Wallander, when you read those books you can imagine the life that a private investigator has. They are very interesting. Each book is about a different case.
I have never thought about working as a private detective.
