March 1941 and the Nazis have occupied British soil. While the Doctor investigates a possible problem in the timeline, Bernice finds herself facing a situation she hoped she'd never have to face...
Benny, Chris Cwej, Roz Forrester, with appearances by Mel.
Page 18 Mainland Britain (despite the cover, the TARDIS is not on the Channel islands, except possibly for the prologue). The events take place in March 1941, but the TARDIS has been there since December 1940. The Doctor and Mel were also in Cairo in 1936 (flashbacks).
Page 230 Benny materialises the TARDIS in a different part of the city, homing in on the Doctor.
It's not essential, but Just War provides another side of the Second World War, last seen in Timewyrm: Exodus.
Page 106 The Doctor is suspected of being the mysterious spymaster Doctor von Wer, the name the Doctor took in The Highlanders.
Pg 42 "The Doctor was in the middle of an anecdote. '...and when I turned around, they were all wearing -'"
Pg 125 "'...eyepatches!' he finished." This is Nicholas Courntey's anecdote from Inferno when (all together now) he turned around and they were all wearing eyepatches.
Page 159-160 Benny connects the Nazis to Daleks, referencing them in just about every possible way, except saying it outright.
"Two syllables, harsh in the mouth [...] Evil. [...] They exterminated everything that wasn't like them. [...] Indestructable monsters. [...] Divide and conquer. Invasion. [...] Advance and attack. Attack and destroy. Their right arms stuff, extended in a permanent salute. [...] Their rightful place, supreme being in the universe."
"A planet full of graves" is a reference to Heaven, which was a planet for the dead (killed in Dalek wars), that Benny was investigating when she met the Doctor in Love and War.
"Remembrance Day" Remembrance of the Daleks.
"Power. Conquer and destroy. [...] War machines pouring from their production lines" Power of the Daleks
"Genesis: an insane genius, wounded in last war. Wanting the best for his people, knowing that they must change in this hostile environment, become harsher, more disciplined, more loyal. Change their very genetic makeup. [...] Scintists, working in laboratories, conceiving new terrors [...] Germ warfare Powerful explosives. Their supreme ruler barking orders. I obey.[...] Racial purity. They ran slave camps, killed their prisoners for sport. Experimenting on the inmates. Twisted science. Permanent warfare." Genesis of the Daleks (and The Daleks)
"Their Nation must return to its former glory" Terry Nation.
"Resurrection." Resurrection of the Daleks
"Master plan" The Daleks' Masterplan
"The future, with London in ruins." The Dalek Invasion of Earth
"Destiny" Destiny of the Daleks
"Planet, Doctor, not universe" Planet of the Daleks.
"Revelation." Revelation of the Daleks.
Roz has a dream of dying violently, prefacing So Vile A Sin. In that book (page 306) we also find out that she kept a wedding dress, with white high heels, in the TARDIS, indicating that she was planning to return to George Reed.
Page 256 Aside from the Doctor, only one character is mentioned in both Exodus and Just War - Albert Speer, the famous Nazi architect.
