are my memories of Robots of Death.
Always a fan of the Agatha Christie locked room mystery, Chris Boucher gave us the sandminer murders.
Claustrophobia at its finest as the killer and the victims are all confined together and no one knows who is which.
Add to that the Asimov Three Laws of Robotics and a cracking supporting cast not to mention one of the best lines of dialogue outside "City of Death" in "Do not throw hands at me" and you have quality entertainment at its finest.
