Marking the grave

If you truly believe in the supernatural myths they tell you, would you wanna prove its existence? Or would you mark its forgotten grave? The forgotten spirits are spirits who are permanently stuck in the in-between unless they make contact with a human and have the letters "R.I.P." marked on their graves. My name is Mr. X. But, you can call me Mr. X. And, I have a dark and depressing poem to tell.

An elderly WWII Veteran learns about a beautiful spirit lurking in the spring woods and decides to check it out. This spirit, a white vixen, is stuck in the in-between because her grave was never marked.

Note:

No demons are in this poem. And, the title didn't come from the song "Mark the grave".
