Louis Friend is an anagram for IRON SULFIDE which is also known as fool's gold. This name was used in the movie The Silence of the Lambs, as the name Dr Hannibal Lector told the Senator Ruth Martin was Buffalo Bills real name. ( if these names make no scene to you i suggest you read or watch The Silence of the Lambs).
Dr Hannibal Lector; His name is Louis Friend, he was referred to me by my patient Benjamin Raspil.....
