What is the climax in the short story "The Open Window" by Saki?

Theis the most dramatic
moment in the story; it could also be called a turning point. It is the moment when the main
conflict of the story reaches its most tense moment. The main conflict here appears to be one of
the character versus character variety: between Vera, the story's , and Framton Nuttel, a young
man who suffers from an anxiety disorder and has come to pay a visit to Vera's aunt, Mrs.
Sappleton (an old acquaintance of his sister).

When Vera learns that Framton
doesn't know anyone, she is interested to learn that he knows next to nothing about her aunt.
Vera begins to weave a story about an uncle having died in the swamp, her aunt's denial of the
loss, and her own creepy belief that he will return one day with her aunt's brother and a dog
(both of whom were with him); she tells Framton that they all drowned.

Mrs.
Sappleton finally comes in, and Framton goes on and on about his health issues and the treatment
he receives for his weak nerves. Mrs. Sappleton jumps to alert attention when she sees her
husband, brother, and dog, coming toward the house (likely because she is so bored by Framton).
When Framton looks to Vera to "convey sympathetic comprehension," she is "staring
out through the open window with dazed horror in her eyes."

This is the
climax, the moment of the highest tension in the text, as it seems that the men's ghosts have
returned to the house until we hear Vera's next fabricated story and recognize that she is
simply good at inventing "Romance at short notice."
