Skull in the Halloween Tree

 "Cuevos!" sang a far voice up the hill.
  Inside the graveyard, voices echoed the song.
  Leaning against the graveyard walls, some with guitars in their hands or bottles, were the men of the village.
 "Cuevos de los Muertos-" sang the faraway voice.
 "Cuevos de los Muertos," sang the men in shadows inside the gate.
  "Skulls," translated Tom.  "The skulls of the dead."
