Many years ago (when I was approx 12 years old) I checked out a paperback from the local public library on the subject of “strange but true” phenomena. I really don’t remember most of them but the one that still sticks out in my mind was the story of a renowned & meticulous french detective who is assigned to a homicide case. No real clues, dead body on a beach. He discovered a faint footprint nearby that others had missed and came to the conclusion (as it had some distinct trait- club foot perhaps?) that he committed the murder through a split-personality of his. The book went on to say that he was let out frequently when guards were assured that he was not in the “bad” personality mode.
I remember specifically checking to see if there was any disclaimer that these were fictional stories (I was a pretty skeptical 12 yr old) and there were none. This one ranked pretty high on the BS meter but I haven’t heard anyone bunking or debunking this one.
All “French detective” searches get me is Inspector Clouseau references. Anyone?
