Query: Not great, not terrible

This could have been much worse! The only problem was the ending, which seemed hurried and slapped together due to a deadline. Too bad, because the actual 'investigation' was engrossing - though the denouement was so disappointing that in my disgust I forgot that I actually enjoyed the rest of the book.If you're into forensic investigations, this book is for you. It was too technical for me, not enough action, not enough profiling . . . I won't be reading another. Though it was good while it lasted (see above: Four stars).
