Made of Steel
Roots: There are references to David Attenborough, Einstein, Radio 5 Live, Rolls Royce, Isaac Newton, and Frankenstein.
Goofs: Wondering how the Cybermen avoided being sucked into the Void, it never occurs to the Doctor that they might be the Cybermen from his own universe that he's encountered a very large number of times...
The Cybermen know about the events that transpired in Torchwood HQ and they want the Doctor to open the rift. So what are they planning to do about the millions of Daleks that were also sucked into the Void and that were in the process of exterminating them all?
Dialogue Triumphs: "When people are faced with the unbelievable, they tend to react by not believing it."
Continuity: The handful of Cybermen here avoided being sucked into the Void because they were converted on Earth, using materials from this universe. They want the Doctor to open the Void and release their army.
The Doctor carries a bugle-like object which works much like a duck-call, but on dinosaurs. The Doctor claims to be a genius. He eats ham sandwiches whilst consulting with Major Burton. The Doctor used to rig up simple space-time portals whilst at school.
Rachel is an old friend of Martha's and a fellow medical student. Fanshawe is another friend and medical student. Martha's Mum and Dad dragged her to visit the Millennium Dome whilst she was still a teenager. A Cyberman crushes Martha's mobile phone.
Links: Army of Ghosts/Doomsday. Martha recalls Adeola's failure to return from Canary Wharf tower (Smith and Jones). The website that the Doctor visits is probably Clive's (Rose), which Mickey later took over (Aliens of London/World War III). In a nod to his Fifth incarnation, the Doctor notes that he used to like a game of cricket.
Location: Prehistoric Earth, the Jurassic Period; London, c2007.
Unrecorded Adventures: The Doctor and Martha recently visited Mount Vesuvius, apparently during an eruption.
The Bottom Line: Easily the best thing that Dicks has written for some time, since the "Quick Reads" imprint basically demands novels of the length and complexity of his old Target novelisations. As a result, it's a slight affair but very entertaining; Dicks has a handle on the Tenth Doctor, although as an early glimpse at Martha this doesn't really give many clues about Freema Agyeman's performance.
