This book sounded good and even started ok (it was well written if nothing else) but by the time I finished it I found it to be one of the most annoying books I've read.
The book was supposedly written by the 'grandmother' of one of the victims. The link between the victim and the author was so tenuous that to call her the 'grandmother' or 'step-grandmother' was laughable and smacked of someone trying to make money out of a very tragic situation.
The author wasn't really involved in this case (although I think she had convinced herself by the end that she had solved it single-handedly!) but she was a private investigator who did some research into it. This would have been fine and getting a PI view of a case would have given a good angle but it didn't quite work out that way.
The author saw fit to almost skim over details of the crime but to include every mundane, pointless detail of her conversations with her family and friends (yawn). I found myself skipping through the sections of the book that were about her (probably about a third of the book in total).
While this woman obviously cared about the case, she wasn't really anything to do with it. It's very easy to say that you knew who it was after the fact - if she had been so sure and had so much evidence, why didn't anybody listen to her at the time, I wonder (she described a scene where she took all her evidence to the FBI who apparently threw her out before she finished her first sentence)!? And it doesn't seem that she tried very hard - even when leads seemed to 'drop' into her lap, it appeared that she left them for weeks before following them up, if at all.
The most irritating bit of the book was after the murderer was finally apprehended (and only because of another crime he committed). The author's husband said to her (twice!) 'You did it, you got him'. I was wondering if I'd been reading a different book because, as far as I could see, the author had no part in it at all - she merely had some suspicions behind the scenes.
The whole book was very annoying and also did that annoying low-budget thing of printing the photos on cheap paper so they were hard to make out. I wish I'd spent my money on something else because this was a big disappointment.
