This was really good...besides being predictable, having a few bizarre choices, and being obviously a man trying to write from a woman's perspective (we aren't generally that surprised when a tough female cop has an effeminate voice, for example). And he maybe should have researched child psychology better before writing this. Good, old fashioned whodunnit, in more ways than one (I refuse to believe even Baby Boomers are this internet illiterate). The film noir references were the only clever parts.
