One star short of perfect because of the open-ended and unresolved plot, but by far the most eerie.
Pay particularly close attention to the frantic, pale, brown-haired woman at the door in the beginning of the episode. It haunts you, so be aware.
The following scenes are harrowing and brutally violent for the program, which does not often venture into such gore-soaked territory.
When the truth of the investigation becomes clear, the vise-tight grip of tension throughout the episode escalates, until a confrontation between the normally rock-solid Det. Logan withers under intense scrutiny by Chesley Watkins.
Perfectly venal character attributable to Whoopi Goldberg taking the part as seriously as she always does. But is there a resolution to this important episode?
Do not watch this episode if you are easily frightened or agitated. You will not sleep well.
