Query: Disappointing

I've read all of Faye Kellerman's books and was looking forward to this one, but I had to force myself to go beyond the first 30 pages or so. It sounded as if she started writing the book without knowing where it was going. The plot was confusing. The cop language sounded forced. Do cops today really still say "grub", as in "lets get some grub" ? which appears more than once in one form or another. I also find it hard to believe that a college-educated cop is such a rarity on today's police force.
