Human remains found at the bottom of a well are matched to a woman who disappeared on October 30, 1938; the night of Orson Welles' infamous "War of the Worlds" radio broadcast, which many people mistook for a real Martian invasion. Meanwhile, for Vera, a chance encounter at a hospital might mean a second chance with Toni.

- The 100th episode.
- As with many cases from the 30's and 40's, the older actors are much younger than the character they play are supposed to be. Ralph Waite was only ten years old at the time of the real "War of the Worlds" broadcast. Julianna McCarthy was only nine. Peter Haskell was barely four years old (his birthday is October 15, and the broadcast was on October 30). Lawrence Pressman wasn't even born until the following year. Len Lesser comes closest to being his character's age. He would have been just over a month short of his sixteenth birthday.
- This episode draws many parallels with the first season episode "Churchgoing People". In both cases, the victim was murdered in their home (then discarded elsewhere) by their spouse shortly after the revelation that they'd been seeing someone else. In both cases, the killer suffered from Alzheimer's in the present and was cared for by their son (who initially protects them, to some degree, from the investigation). In both cases, the killer, in their confused state, confuses Lilly with someone else, which she uses to her advantage. Both episodes end with the killer being arrested or locked up, though it seems unlikely, in either case, that the killer would be considered fit to stand trial.
- Several fans were confused by Stillman's mentioning driving around with his wife and kids at the time of the "War of the Worlds" broadcast, noting he couldn't possibly be that old. In fact, he was merely reading someone else's account.
- In all likelihood in his late nineties if not older, Felton Metz is the oldest doer seen on the show, excluding the long-deceased killers in "Torn" and "Beautiful Little Fool."
