Review title: plot and characters both a mess
Product review: I suppose to get into "suspense," you need a pedophile, lots of murders, and a supposedly competent woman who wanders alone into a darkened empty area just after having received a death threat. As some other reviewers noted, to consider a thieving pathological liar who incites others to murder, who pays no heed to the consequences of her actions and who is consistently foul-mouthed and minded a "victim" just stretches things too much. It's as if a pedophile in the plot serves the same function as a demon: absolves everyone else of responsibility and awareness. Add in forensic and medical improbabilities, and this is really a mess.
