#19 Another Letter Series

first off I would like to officially add this to the rules via this post
I would ask that if you have heard a riddle before, or some version of it or
even saw it on the internet, then I would ask you to please refrain from posting the answer,
simply post that you have heard the answer before, and then contact me with the correct answer (preferably soon after) and then perhaps I will make a point system involving such a phenomena, but I try to keep the riddle variety vast and I don't think that will happen much
with out further to do. . . the riddle

What letter is missing from this sequence:

A A A A ?A A A A A A

hint #1 "alphabets"
hint #2 "ancient"
the unpresidented hint #3 "GREEK"

just to let you know the answer is not "A" I repeat Not "A"

#14 Old Mr. Tidy

Old Mr. Tidy was found dead in his study by Mr. Fiend. Mr. Fiend recounted his dismal discovery to the police. " I was walking by Mr. Tidy's house when I thought I would just pop in for a little visit. I noticed his study light was on so i decided to peek in from the outside to see if he was in there. There was frost on the window so I had to wipe it away to see inside. That is when i saw his body. So I kicked in the front door to confirm my suspicions of foul play. I called the police immediately afterward."
The officer immediately arrested Mr. Fiend for the murder of Mr. Tidy. How did the officer know Mr. Fiend was lying?
