Advertisements PBS called this episode 4-1, but all other sources called it 5-1. Did they goof, or are they using some altenate numbering scheme? Maybe some "new math" in their schedules? While most of the episodes of Lewis were logical and made some sense, I just got totally lost with this one. I get why Jud had to be killed ten years ago, but not exactly why the new bunch of murders were being committed today. Maybe I wasn't paying attention, or I just need to see it again, but I was really confused by the character's motivations? Why was Poppy sending out all those accusitory letters? Do I need to diagram this? Oh, and I guess not smoking isn't working for Hathaway.
