Masterpiece Mystery is one of my favorite shows on television. It runs a bunch of different mystery stuff, mostly old Agatha Christie retreads (my favorite!), but also some other series like Inspector Lewis and Foyle’s War. Foyle’s War is about some guy who’s too old, nerdy, and wimpy for military service (the British military seems to think so, anyway), so he’s a police inspector who solves murders and stuff instead of fighting during WWII. It’s pretty good, but they missed out on something that could have been fun for the viewers.
What they should have done is to have all of the diditers (the ones that “did it”, that is, and so they are the “diditers”) be people who have been arrested by Foyle before for something else, and so when he arrests them for whatever murder or crime, they can say: “Curses, Foyled again!” Then the show could always end the same way, like in Scooby Doo, with the: “And I would have gotten away with it too if it weren’t for you meddling kids and your dumb dog!”
