It sounded like it should be a good mystery. There was no mystery. Filmed in a TV interview show style - like "Dateline". Interview then re-enactment, only in this case we saw what happened. I wouldn't call this English family eccentric. They seemed more quirky, self-centered, not terribly cognizant and caught off-guard taking in a friendly stranger. The dog was the only normal one and he had 3 legs. And, yes, they do get accused of murdering the stranger, which they didn't do. Guilty of culpable stupidity. I don't know that I'd watch it again, but it was droll and I don't begrudge the time.
