I only recently discovered Minette Walters and have been picking off her novels one by one. The author is a master story-teller, revealing the background and "clues" gradually, as would occur in a developing criminal investigation. What I find interesting about this particular story is that the main character, Olive, is not an "attractive" person, in either appearance or nature, and it seems that this encourages others to easily believe that she is capable of evil things. Would a slim, good-looking, pleasant person be judged in the same way? Do we find it easier to believe "ugly" people capable of ugly acts? I find that this is more interesting that the actual "did she or didn't she" that she story reveals.
