What is one example of irony in "The Open Window," and what type of irony is it?

There is verbal irony in The Open Window by Saki, because
Vera talks about a "tragedy" that had occurred; however, she knew
that the "tragedy" was a lie, when Framton Nuttel believed this story to be
true.

You can tell that Vera is lying because at
the end of the short story, Vera mentions how Mr. Nuttel had developed a fear of dogs,
so must of been afraid of the spaniel. The reader heard the only conversations between
Vera and Mr. Nuttel, and it never mentioned anything about
dogs...

What the names in The Open Window mean
relative to the content of the story:

Mrs.
Sappleton: "sap" = fool; believes anything or taken advantage if
easily

Framton Nuttel: "framton" = frantic , "nut" =
crazy

Vera: "ver" = veer people off in the wrong direction
, "vera" = truth (so there is irony within the names as well).
