What are Vera's main characteristics in Saki's "The Open Window"?

Vera
might be compared with adolescent Briony Tallis in the novel Atonement by
Ian McEwan, published in 2001. The novel was made into an excellent motion picture in 2007 and
won many prestigious awards. It won an Academy Award for Best Original Score and was nominated
for six other Academy Awards, which is quite unusual for a foreign film. The photography,
costuming, and settings are all exceptionally good. Both Vera and Briony appear innocent and
ingenuous, but both have hidden mean streaks. Vera's transgression is comical, but Briony's is
very serious. Both girls tell untrue stories, but Briony's story gets an innocent man sent to
prison.
