What did Framton think of Mrs. Sappleton in "The Open Window"?

It is important to
remember how
Framton's opinion of Mrs. Sappleton, a woman he has never met before, has
been
coloured completely by Vera's account of why the window is open and what
supposedly happened to
Mrs. Sappleton's husband and brothers one day.
Therefore it is understandable that Framton finds
meeting Mrs. Sappleton a
horrible experience when she talks about her husband and brothers as if
they
were still alive. Note the following quote:

She
rattled on cheerfully about the shooting and the scarcity of
birds, and the prospects for duck
in winter. To Framton it was all purely
horrible.

Framton
therefore thinks
that Mrs. Sappleton is so deranged by her grief and the tragic accident that

happened that she is completely unable to accept the reality of the tragic accident that
Vera
told him about. Framton's opinion of his host is therefore a direct
result of Vera's
manipulation, which it is only the reader who comes to
realise, as Framton leaves far too
rapidly to discover the way he has been
tricked.
