I have read Cliff Black stories before but "Perfect Crimes" was like reading an outline of a story or a first effort of a college writer; maybe high school.  I almost quit reading in the first chapter but decided to finish it and hope it got better.  The writing was literal and linear, meaning from the very beginning the reader knew about the crime.  Much of the internal dialogue was repetitive and in some cases unnecessary.  There was no mystery or clues to ferret out what was happening toe the main characters.  Two characters, a husband and wife, find themselves in the midst of a criminal act against them and choose not to engage the police because they think they will get in trouble.  This despite the fact the police begin to uncover clues that something is amiss.  The main characters brother is a policeman and instead of interrogating the main character just accepts "I'll tell you when I retire" statement in response to the question "What is going on?"  No police officer would accept this.  Nor would anyone else, particularly a family member.  Just not believable at all and the ending was....what can I say...incomplete.  It felt as if I fell off a cliff with half of the story unresolved.  Too bad.  A good premise but poorly written.
