“The Spook House,” an 1899 short story by Ambrose Bierce is suitably spooky for the season, but not in the way you expect.It was a favorite of H. P. Lovecraft, who praised its “terrible hints of a shocking mystery.” Also, a macabre bit of poetic whimsy from A.E. Houseman, and an intruder is welcomed in Mr. Ridenour’s library.
