How does the author use foreshadowing in the novel, Valencia and Valentine?

Krause allows for a sense of foreshadowing when she drops hints in the narration about how the two stories (Valencia and Valentine's) may intertwine. For example, in Chapter One, the narrator reveals that Valencia is a debt collector, and in Chapter Two, the narrator remarks that Mrs. Valentine often accrues credit card debt so that she can talk to debt collectors. The close placement of these details seems to imply that the two women would meet in a phone call related to debt, but this is not what occurs.

Valencia’s chapters are written in past tense, whereas Mrs. Valentine’s chapters are in present tense. This serves as a hint that Valencia’s story takes place in the past and Mrs. Valentine’s in the present since Valencia and Mrs. Valentine are later revealed to be the same person. However, it is so subtly placed into the narration that it likely goes unnoticeable by the reader.
