The Black Dog of the Hanging Hills

[Erik T. Burns]

 The story is written by W. H. C. Pynchon, grandfather of acclaimed author
Thomas Pynchon, and was clearly labeled as fiction by *The Connecticut
Quarterly*, which published poems, fiction and nonfiction. The elder
Pynchon was 31 and a Harvard-educated scientist working as a professor at
Trinity College in Hartford. Over the years, perhaps because of the
similarities between Pynchon and his fictional narrator, the story came to
be taken as truth rather than fiction.
