“The Robots of Death” is a badly named but otherwise fantastic story from 1977. It’s one of my favorites from the Tom Baker years. It’s written by Chris Boucher and was the final Who serial to be directed by Michael E. Briant. The great guest cast includes David Collings, Russell Hunter, and Pamela Salem. I absolutely love it. It perfectly places an Agatha Christie plot in an Isaac Asimov world, with tips of the hat to Frank Herbert and Poul Anderson along the way, and then designs the costumes and rooms of this huge, moving mine with a lush jazz age sheen. Our suspects and victims are all idle rich, with fancy clothes and gaudy makeup, and the robots who do the work are built to be more beautiful than functional.
Our son is being incredibly observant but his deduction skills need a little tuning. He didn’t see what we were meant to infer from the over-the-top headdresses and lush common rooms of the mine, but he did catch that there are three color schemes for the robots: black, silver, and emerald. The second episode explains that the black robots are mute D-class and the lone silver robot is the controlling SV-class, but it also gives us a black robot who talks a great deal to Leela when none of the crew is present to hear his voice. Wonder what’s up with that?
