It being October, here is one I wrote a while back,
something creepy enough for the season I hope....

"Black Horse of Death is Nigh"

They sold it off to save the family
the stallion with the coat of onyx
that stalked their fields every night
refusing to be stabled even in storms.
Times were tough, choices were few
so off to the dog food factory the sent it.
But three nights later, like a ghost
it returned to the pasture's grasses
where he foams at his mouth awaiting
the children to come and try to ride him
so he can take them to his new master
down in Hell's darkest and deepest pits,
where the nightmares neigh in glee
knowing the Black Horse of death is nigh.
