The Murder of Tom Bombadil

Tom Bomdrill had dealt with the joke all his life. "Tom Bombadil" he was called since grade school, after the name of the character in 'Lord of the Rings'.
Tom embraced the nick-name, even running his life round the strange stanza'd poem.
But forty years of marriage can change a man.
Even a normal man like Tom Bomdrill.
One August day, taking one barb too many from his wife, in a moment of passioned rage, he murders her.
For days he sits with the body in the bedroom, haunted by the sight of his dead wife, and the mutated echoes of JRR Tolkein's poetry in his head.
Wrapped up in his own guilt, he does not see any of the strangeness around him.
He decides to walk to the local police station and report the crime, but the simple act does not go exactly to plan.....
When the police can't find a body, something is wrong with the world somehow.
