Thanks to my local Library, I watched "Blackheath Poisonings" in its entirety. The excellent cast includes Judy Parfitt, who is absolutely perfect as the deliciously vicious family matriarch. There are a few recognizable faces including Zoe Wanamaker and Patrick Malahide. Warning! If you want family fare, this ain't it. There are many Adult Themes in this movie. But those of us who live on Planet Earth know that there were many sexual perversions in the Victorian Age just as there are today. They were just well hidden under a hypocritical veil of moral decency. This mystery unveils them all, with death by poisoning woven in. It begins by introducing us to a wealthy family that owns a Toy factory. We learn immediately that there are extramarital sexual relations going on and sooner than we catch that fact, someone dies. When a second death occurs, the smartest member of the family starts hound-dogging around. The police put one person on trial believing they have caught the real killer. But is it really the true killer?? I can guarantee that you won't guess the twists and turns that lead to the real killer. I kind of guessed the additional twist at the end. I love mysteries set in bygone times, especially Victorian dramas. In "Blackheath Poisonings" it's great fun and entertaining to watch. The costumes are great, so are the sets. The actors each do a terrific job of making their characters dis-likable, despicable, or likable. I have cable TV and I've seen stuff like this on USA, TNT, PBS and other non-premium channels, so I wasn't shocked at the adult content like some who've commented here. It also didn't surprise me in the least that all this happened in a rich, so-called respectable, Victorian family. That's part of the entertainment factor!
