This is a ghost story. A story which one might call scientific in comparison with the ordinary tale of shades and spooks. The ghost of a dwelling as well as of its inhabitants is a novelty in the literature of the supernatural, yet, if one accepts Mr. Beale's reasoning, both come within the limits of possibility. Do you think you understand ghosts? Now you will. Paul Henley, seemingly summoned to a mysterious rural Virginia mansion from his home in New York, finds himself as a guest at a remote, dilapidated colonial house with a host and a hostess every bit as mysterious as the house itself. Might Dorothy, his hostess, somehow be implicated in the hideous crime which he came to know took place in the hidden depths of Guir House some years ago? He hardly thought so, she seemed so innocent.
