The climax in " Roman Fever " by Edith Wharton appears at the very end of the story, however the author, she has prepaired subtly for this shocking ending by using a series of foreshadowdings and hints before reaching the climax.
At the first part of the story, the foreshadowings mostly concentrates on Mrs. Ansley.

The author foreshadows more clearly as the story goes along. The scene when Mrs.Slade's gaze "turned toward the Colosseum" (middle of...
