== Letter ==
"Hell March 13, 1919 
Esteemed Mortal: 
They have never caught me and they never will. They have never seen me, for I am invisible, even as the either that surrounds your Earth. I am not a Human being, but a spirit and a demon from the hottest Hell. I am what you Orleanians and your foolish police call the Axeman. 
when I see fit, I shall come and claim other victims. I alone know whom they shall be. I shall leave no clue except my bloody axe, besmeared with blood and brains of he whom I have sent below to keep me company.
If you wish you may tell the police to be careful not to rile me. Of course, I am a reasonable spirit. I take no offense at the way they have conducted their investigations in the past. In fact they have been so utterly stupid as to not only amused me, but His Satanic Majesty, Francis Josef , ect. But tell them to beware. Let them not try to discover what I am, for it were better that they were never born than to incur the wraith of the Axeman. I don't think there is any need of such a warning, for I feel sure the police will always dodge me, as they have in the past. They are wise and know how to keep away from all harm. 
Undoubtedly, you Orleanians think of me as a most horrible murder, which I am, but I could be much worse if I wanted to. If I wished, I could pay a visit to your city every night. At will I could slay thousands of your best citizens, for I am in close relationship with the Angel of Death.
Now, to be exact, at 12:15 (earthly time) on next Tuesday night, I am going to pass over New Orleans in my infinite mercy, I am going to make a little proportion to you people. Here it is: I am very fond of Jazz music, and I swear by all the demons of the nether regions that every person shall be spared in whose home a jazz band is in full swing at the time I have just mentioned. If everyone has a Jazz band going, well, then, so much the better for you people. One thing is certain and that is that some of your people who do not Jazz it out on that specific Tuesday night (if there be any) will get the axe.
Well, as I am cold and crave the warmth of my native Tartarus, and it is about time I leave your early home, I will cease my discourse. Hoping that thou with publish this, that it may go well with thee, I have been, am and will be the worst spirit that ever existed either in fact or realm of fantasy 
-The Axeman." in response the police of New Orleans told everyone to play Jazz music all night long and that night there were no reported deaths and the Axeman stopped on October of the same year.https://en.wikipedia.org/wiki/Axeman_of_New_Orleans#Suspects
