Death strikes home when Audrey Martin, the wife of Sheriff Tupper's night deputy, turns up dead on her kitchen floor. While Sheriff Tupper originally dismisses it as suicide, Jessica has her doubts. The investigation reveals the sordid secret life of Mr. Martin and multiple local ladies, but will any of the secrets reveal how Mrs. Martin met her end?
This episode includes examples of the following tropes:
- Accidental Murder: George the mailman sneaked into the Martins' house late at night to steal Audrey's winning lottery ticket, and she surprised him and threatened him with her husband's spare gun. It went off as they struggled.
- Ad Hominem: After being accused of causing Audrey Martin's death, George the mailman pulls Sheriff Tupper aside and says that Jessica has been touchy since he caught her and his deputy in a sensitive position. However, Jessica has already told Sheriff Tupper about the incident and he doesn't buy George's insinuations.
- Awful Wedded Life: Neither Jonathan nor Audrey seem to have been very happy in their marriage. Audrey brushes off all Jonathan's attempts to do something nice for her and moans about how miserable she is and how she should have married another man in front of him. On Jonathan's side, he runs around with multiple other women.
- Book-Ends: Near the beginning of the episode, Sheriff Tupper intrudes on Jessica and Seth's Italian dinner to return a book and samples the calamari. At the end of the episode, he intrudes again and gets a taste of escargot.
- A Deadly Affair: For a while, Jessica and Sheriff Tupper both consider whether Jonathan or one of his women killed Mrs. Martin. However, her death turns out to be an accident unrelated to Jonathan's cheating.
- I Ate WHAT?!: Two examples, both involving Sheriff Tupper. When he tries the Italian dish Dr. Hazlitt is cooking for himself and Jessica, he likes it until Seth tells him he just ate squid. While the episode ends before either Jessica or Seth can explain what escargot contains, they're clearly thinking he'll have a similar reaction.
- Lighter and Softer: Despite the slightly dark ending, it's mostly just a hilarious tale of a granny chaser sleeping with a different woman every day!Amos: Even The Lord rested on the seventh day.
- Motor Mouth: Jessica begins using a lot of words at high speed when she's trying to get away from Deputy Martin and then get him out of the house after the massage he's giving her for her neck pain leads into more intimate touching.
- Prompting Nudge: When Jessica tells Beverly that Dr. Hazlitt became very concerned when she didn't arrive on time Thursday, Sheriff Tupper has to bump the doctor's elbow to get him to make the appropriate response.
- Public Secret Message: Jonathan and each of his mistresses have a code for their rendezvous which is called in over the police radio. Jessica discovers it after noting that certain complaints are registered by certain ladies with uncanny regularity (eg, Mrs. Simpson saying that her cat got herself stuck up a tree every Tuesday).
- Shout-Out: Presumably the title refers to the play If It's Tuesday, It Must Be Belgium.
- Skewed Priorities: Sheriff Tupper seems more bothered by the ladies' attraction to his night deputy than by his philandering. At one point, he asks what Jonathan Martin has that he doesn't have.
- Third Wheel: Sheriff Tupper comes in to return one of Frank's old fishing books and remarks that the food smells very good. Dr. Hazlitt shows clear annoyance that Amos has intruded on his evening with Jessica.
