Paul Cameron heard voices.
There were two of them. They were whispering to each other in the bones
of his skull, wearily, interminably, making monstrous plans to conquer
the Earth....
Cameron was an educated man, an English professor at a leading
university. Was he going insane? Or was he really tuned in somehow on
the telepathic conversations of a recon patrol for a terrible Martian
invasion?
He tried warning the others, but nobody believed him.
And then one day the voices stopped for a moment. "_Wait_," one of them
said then. "_There's a listener. We've got to get the listener. When
you find out who he is, kill him...._"
