What does Vera make Framton believe about her aunt? What does Vera explain to her aunt about Framton?

Upon
meeting Framton Nuttel, Mrs. Sappletons mischievous niece Vera creates a tragic story regarding
her aunt's large French window in hopes of scaring the neurotic stranger. Vera anticipates the
arrival of her uncles coming home and entering the house through the large French window.
However, Vera tells Mr. Nuttel that these uncles tragically passed away three years ago while
they were shooting, which significantly affected her aunt's mental state. According to Vera,
Mrs. Sappleton's husband and her two brothers were engulfed in a treacherous piece of bog and
never returned. She goes on to tell Mr. Nuttel that Mrs. Sappleton never fully recovered from
the tragic event and keeps the French window open every day, hoping that they will eventually
return.

When Mrs. Sappleton's husband and brothers finally arrive home from
shooting, Framton sees them and believes that they are ghosts. Without saying goodbye, Mr.
Nuttel dashes out of the home in complete terror, which confounds Mrs. Sappleton. Vera once
again fabricates a story to explain Mr. Nuttel's puzzling reaction by telling her
aunt,

I expect it was the spaniel...he [Framton] told me
he had a horror of dogs. He was once hunted into a cemetery somewhere on the banks of the Ganges
by a pack of pariah dogs, and had to spend the night in a newly dug grave with the creatures
snarling and grinning and foaming just above him. Enough to make anyone their nerve.
