How does the opening event of Dana describing the loss of her arm and Kevin being questioned by the police connect with foreshadowing?

The
fact that Dana has lost her arm in the present day gives us an immediate understanding that what
led to this will be explained with flashbacks. The book gives us this information in a , not in
the first chapter, which is an important distinction. As a prologue, the information is more
directly given to the reader. The narrator specifically says that she lost her arm on her last
trip home, which makes us aware that there were multiple trips before this last one. The reader
is also told that time may function differently, as Dana has lost a year of her life. It is yet
unclear if this isor a function of speculative , but we know that we will find out. These
together make this momentof the rest of the book, some of which takes place shortly before the
prologue, and some of which takes place far before the prologue, in a different
century.

In terms of Kevin, there is foreshadowing that he is aware of some
violence and potentially involved in it or covering up for it. The scene intimates violence
without explaining the details behind it. Kevin talks to the police because they assume Dana is
being abused since her story, that she got stuck in the walls of her house, is so unusual. The
reader is left confused over whether the arm was really crushed or if Kevin had something to do
with it. Thus a tension is introduced that will be understood and resolved by the end of the
book.
