How does the setting contribute to the atmosphere of the story "The open Window ?

The setting of the story "The Open Window" by H.H. Munro
(Saki), is the Stappleton house: A house in the country, we can assume it to be a
country estate, often owned by the Victorian and Edwardian middle classes to spend time
with nature after the London season is over.

A country
house is an interesting setting for this story because it immediately instills in the
reader a feeling of isolation, separation, and quietness. This, combined with the fact
that Mr. Nuttel went there to cure his nerves, hints at a semi-Gothic scenario involving
a lonely place in the middle of nowhere.

This is effective
because, as we see later, the story that Vera creates to scare Frampton is quite eerie
and goes perfectly well with the atmosphere of the place: Foggy, quiet, isolated. In a
typical Gothic story, something creepy always happens in a setting of that kind. Saki
treated this "horror" aspect of his funny short story by providing the perfect scenario
in which Vera's story would seem valid.
