Terrance Dicks has long been a Doctor Who traditionalist, a writer with very clear ideas about both what The Doctor should be like and "Doctor Who" should be like. This novel is, then, an utter surprise as he abandons both of those lines. This Doctor 5 is very little like the Doctor 5 we saw on TV, and very little like any other Doctor. And this story is very little like traditional Doctor Who stories. Ostensibly, the novel takes the reader to the backstory of "Brain of Morbius." The reader gets to see Karn prior to its war-torn ruins on TV, the Sisterhood as a powerful and influential organization, Solon as the self-absorbed chief surgeon, and Morbius on his rise to power. Of course, getting a later Doctor to an earlier period on Karn where he knows all these characters, but they don't know him, is a tricky matter. So, the Doctor spends much time and effort preserving an incognito. That is all fine, as it is. The difficult part for this reader is the elaborate plot Dicks has built around that central idea. To get The Doctor to Karn at the right time, the plot (but not the story) begins when The Doctor takes Peri to a planet unencumbered by civilizations and their various problems, so she can get some R&R. In less than half an hour, Peri is almost fatally wounded by a prehistoric creature, and the Doctor takes her to the best surgeon he can think of - Mehendri Solon, chief surgeon at the Hospice of Karn, a hospital renowned in the galaxy. There is some business with Peri's stumbling upon Solon's secret experiments and The Doctor's surprising uninterest in that, at least surprising to her. There is quite a bit of this before Morbius arrives, nearly midway through the novel. At that point, the novel takes a sudden turn to full not-Doctor-Who territory while using all the trappings of Doctor Who. The Doctor ends up going back to Gallifrey to convince the Time Lords to do something about Morbius. They do, mainly by setting up The Doctor as military leader who gathers forces from various, and given Doctor Who history highly unlikely to join such an endeavor, races. The Doctor becomes supreme military commander, must become everything he hates, but somehow finds that he actually kind of likes it. Meanwhile Peri, of all people, becomes a guerilla leader by accident.
Dicks with his later Doctor Who novels seems to be very interested in war, the phenomenon of war, the political necessity of it, and the tactics of it. With this novel, Dicks has forced the Doctor, who is otherwise both uninterested and opposed to all those things, to share these interests out of necessity.
As I read the book, I kept thinking of it as being much like Lance Parkin's "The Infinity Doctors." Like that novel, "Warmonger" has the recognizable characters, the references to various episodes and periods of the show, the trappings of "Doctor Who." And yet, like "The Infinity Doctors," "Warmonger" reads as if it occupies a parallel universe to Doctor Who's. It reads as a kind of "what if" exercise.
It might have worked in some way. However, Dicks, who is usually pretty careful about keeping his plots tidy, has left many loose ends; plus, he has created an unresolved paradox in which Borusa meets The Doctor and knows who The Doctor is before The Doctor is even born, if I get my time lines right. Certainly, it is before Borusa is a teacher at the academy and the young Doctor his pupil. How is it that the CIA know who The Doctor is before he becomes The Doctor? Why aren't the Time Lords panicking about time paradoxes and crossing one's own timeline? Plus, the whole beginning of the story (though not of the novel, which uses flashback storytelling) when Peri gets injured seems a mere contrivance to get The Doctor to Karn.
Audacious in some ways, "Warmonger" just does not quite hold together well enough to make the ambition pay off.
