I Bury the Living

A newly-appointed chairman of the local cemetery has a large map of the grounds on the wall in his office. Pins on the map represent the plots, with black pins showing those plots occupied and white pins showing those plots sold but not in use. The chairman mixes up some of the pins and discovers that the owners of some plots he inadvertently marked with a black pin suddenly die. He comes to realize that he has the power to cause the death of the plot owners by simply marking their site with a pin.
