Fiona Moore's book for The Black Archive on "The Robots of Death" (including a section on Kaldor City of course) is shortly to be released. And Sci-Fi Bulletin apparently approves:
""Fiona Moore loves The Robots of Death as much as we do, unravelling the various threads that combine to create a pretty much perfect story. And as much as you might think you know there’s nothing new to say here, you might just be surprised. 9/10""
