The author really tried hard to build up the suspense before the reveal, so it would be very odd if they gave it away in the title. I even think they gave away too much, since my first thought was "baby" when I read "in the freezer". I think this kind of story is one of the rare cases where I would have preferred a less revealing title. Some people enjoy reading stories without knowing the end beforehand.
