Neither Mom nor I watch a lot of serialized television. I prefer stand-alone movies. She prefers going to bed with a mystery novel. We've found an overlapping sweet spot of entertainment that we both enjoy in the Hallmark Mysteries and Movies channel.
Most of the following are what used to be called "made for television movies," if that distinction has any meaning anymore in the modern landscape of streaming media. Most of them are based on series of books.
64. (1503.) Murder, She Baked: A Plum Pudding Mystery (2015)
We started by watching the misadventures of professional baker and amateur sleuth Hannah (Alison Sweeney). Mom had read and loved the books. The movies are cute, if heavier on the romance than the mysteries. Alas, Sweeney has moved on to other series and will bake no more murders.
65. (1504.) Site Unseen: An Emma Fielding Mystery (2017)
41. (1480.) Past Malice: An Emma Fielding Mystery (2018)
42. (1481.) Emma Fielding: More Bitter Than Death (2019)
Emma Fielding is the Indiana Jane of mystery fiction, an archaeologist who somehow spends more time chasing murderers than relics. On television, she's played by the botoxed face of Courtney Thorne-Smith of Melrose Place fame. I'm okay with these, but it's not my favorite series.
68. (1507.) Morning Show Mystery: Mortal Mishaps (2018)
69. (1508.) Morning Show Mystery: Murder on the Menu (2018)
70. (1509.) Morning Show Mysteries: A Murder in Mind (2019)
81. (1520.) Morning Show Mysteries: Countdown to Murder (2019)
82. (1521.) Morning Show Mysteries: Death by Design (2019)
These are based on books co-written by Al Roker about a morning-show celebrity whose entire social network appears to be filled with murderers. Holly Robinson Peete of 21 Jump Street has the lead opposite Rick Fox, who could probably be replaced by a block of wood without anyone noticing. I enjoy this series, partially because I like a bit of ethnic diversity in the otherwise lily-white Hallmark landscape and partially because I'm always able to solve them before the halfway point. (They make me feel smart, even though by design a toddler could likely put the clues together.)
85. (1524.) Darrow & Darrow (2017)
86. (1525.) Darrow & Darrow 2 (2018)
87. (1526.) Darrow & Darrow: Body of Evidence (2018)
Unquestionably my favorite of the Hallmark mystery bunch. The younger titular Darrow is Kimberly Williams-Paisley, who I had something of a crush on in the mid 90s in her pre-According to Jim appearances in Steve Martin's Father of the Bride remakes and the Relativity television series I watched with my girlfriend at the time. I could still watch her for hours, and I have.
So that's what my Mom and I do together — even when it isn't Mother's Day.
