I found this episode to be above the already high standard for this series. The opening tragedy, triggered by an apparently drunk-driving mom who kills herself, one of her children and both of her nieces by driving at reckless speed and the wrong way onto a highway ramp is quite shocking and mysterious. The only reason I suspected there was more than meets the eye here is because every episode of L&O deals with pre-meditated murder, not a drunk driving "accident." The skilled writers of this excellent show usually foretell the main story line with subtle hints in the early scenes and that happens here when they introduce the grieving father's cancer-afflicted mother. At first it just looks all the burdens of the world are being dumped on this poor guy.
An earlier post here is wrong about Anita's own condition being unknown to her colleagues. She did indeed inform them in an earlier episode since her treatments would require considerable time away from work. What the brave woman does not want is showy sympathy and pity. This is why the detectives show pleasure at the fact that she has regained her appetite, but they do it subtly. It's been made clear in earlier episodes that she was struggling with being able to eat, due to chemo. You can see their affection for her and how they struggle with supporting her without offending her. She's a great actress and it's quite apparent in these episodes.
