Rich men are being targeted in the strangest possible way, an assassin is breaking into their homes, and showing just how easy it would be to murder them.
There are a wealth of ideas throughout this great episode, so much cleverness, so many mind vending concepts, I don't think I've ever seen a show with such a plot.
Beautifully shot and produced once again, I'm sure many didn't forget Emma Peel's Riverside fight scene, the whole thing looked wonderful.
I've sometimes been a little critical of some of the villains, and it's fair to say that Needle ranks up there are one of the wildest, but George Murcell was awesome here I thought, I really enjoyed his presence.
I know this was written by Philip Levene, but for me it felt like it had come from the imagination of Brian Clemens, it felt to me like an episode of his series Thriller, it had that vibe, that cleverness.
Mrs Peel is definitely getting some classics, and going out in style.
9/10.
