Engrossing crime story with a few minor twists and turns along the way. Satisfying. The nuts-and-bolts of the investigation are detailed in enjoyable fashion, with time spent showing us Hunter and McCall on the trail of the prime suspect (in traffic and, later, in a hotel). As ever, the soundtrack and the little details make these scenes (like most of the scenes in any given episode) very enjoyable to watch. Curiously it is Rocco (a highly regarded character actor) who gets least to do in the episode. The rest of the guest cast get plenty to do. And are very good. Especially Morgan who brings a steely-eyed determination to her character this is fun to watch and is sufficiently strong to make us think she might actually be the killer, even if it makes no logical sense for her to do so yet. Logic is the story's biggest asset. Joseph Gunn and Joe Menosky's script frequently skips developments in the action. But because everything that happens off-camera makes perfect sense when you know the full story it is very rewarding for the viewer to watch and piece it all together along with the detectives. Typically of this show, the lead characters are smart. We are never ahead of them. Every time the narrative returns to them they are accurately piecing it all together. And if they are wrong about anything, it's only because the writers are trying to misdirect us a little bit. And it pretty much works.
