When it comes to crime, it's not always a question of "who dunnit?" Sometimes there's more mystery in the why or the how. And what about the clever few who carry out what appears to be the perfect crime? Or whose most essential selves are changed by the crimes they commit? And what about those who know the identity of the murderer but keep the information to themselves? These are some of the questions that these six stories begin to unlock as they draw us into the inner workings--the thoughts and emotional machinations, the recollections and rationalizations, the dreams and desires--behind both murderous cause and effect. And no one gets inside the head of a perpetrator--or makes it a peerlessly thrilling and entertaining read--like the incomparable P. D. James.
