Every detective has a certain kind of case that he or she finds almost unbearable, against which the usual shield of practiced professional detachment turns brittle and untrustworthy. Cassie, though nobody else knows this, has nightmares when she works rape-murders; I, displaying a singular lack of originality, have serious trouble with murdered children; and, apparently, family killings gave Sam the heebie-jeebies. This case could turn out to be perfect for all three of us.
That's kinda the MO for the whole series... Each book focuses on a different detective working the case most likely to strip them down to their bare essentials
