Interesting tale about a writer who feels that his very being is being taken over by an entity that eventually plans to take over the world. He thinks it is holed up on a big boat that sits in a port that he can see from his residence. He determines that the boat, along with the entity, has to be destroyed. The writer of the original story, Guy De Maupassant, is as interesting to read about as the episode was to listen to. Apparently, he had a form of madness near the end of his life and attempted suicide, and this story was written during the midst of it.
