How does Framton Nuttel react to Veras story of the great tragedy" in Saki's "The Open Window"?

Framton
Nuttel is an eccentric hypochondriac who visits the country under his doctor's advice to cure
his nervous disorder. Upon visiting Mrs. Sappleton's home, he is greeted by Vera, Mrs.
Sappleton's niece. Vera then proceeds to frighten Mr. Nuttel with a lie about her uncle and his
two brothers-in-law drowning in a bog. Vera begins by telling Framton that three years ago her
aunt suffered a , which is why they leave the large French window open. Vera then tells Mr.
Nuttel that three years ago her uncle and his two brothers-in-law went off to shoot and drowned
in a treacherous bog. She also tells Framton that their bodies were never discovered, and her
aunt sadly believes that one day they will return through the open French window.
When Vera finishes her aunt's tragic story, Framton feels unnerved and frightened but is
relieved to see Mrs. Sappleton enter the room. However, when Mrs. Sappleton begins talking about
shooting, Framton becomes hysterical and finds the topic of conversation "purely
horrible." Framton's horror intensifies when Vera's uncles arrive, and he
believes they are ghosts. Framton reacts by racing out of the home in terror without saying
goodbye.
