It's not always a question of "whodunit?" -- sometimes there's more mystery in the why or how. And although we usually know the unhealthy fates of both victim and perpetrator, what of those clever few who plan and carry out the perfect crime? The ones who aren't brought down even though they're found out? And what about those who do the finding out who witness a murder or who identify the murderer but keep the information to themselves? These are some of the mysteries that we follow through those six stories as we are drawn into the thinking, the memories, the emotional machinations, the rationalizations, the dreams and desires behind murderous cause and effect.
