Laura, you asked about the Hallmark channel holiday movies. So far I have found two:
Halloween: The Good Witch’s Destiny
It is premiering this Saturday (Oct. 26) right after they show a run of all of the past The Good Witch movies (at 8:00 PM and also at 10:00 PM) and then on Sunday, Oct. 27 at 12:00 AM and again at 8:00 PM.
Thanksgiving: The Thanksgiving House
It is airing Saturday, Nov. 2 at 7:00 PM and again Sunday, Nov. 3 at 1:00 PM (Central)
As I haven’t seen either of these movies, I can’t vouch for them. (But, I am rather partial to the Hallmark holiday movies.)
Also, you had better consult your TV guides as I could be a little off on times and/or dates (although I don’t think I am.)
(I wrote this as a comment response to Laura’s comment, but decided some of the rest of you might want to know about both of these Hallmark channel Halloween and Thanksgiving movies. They are not mystery movies.)
