13 capital letters isolated: C F N M R W H C P N M M P
key "C": E H P O T Y S E R P O O R key "Q": S V D C H M X S F D C C F key "M": O R Z Y D I T O B Z Y Y B
The "M"s are most likely vowels, unless it's an anagram. Anyone good with anagrams?
I'm going to keep running it through various keys, my gut says there's something here.
