The Story of Martha - Trivia

Trivia

• The beginning of the novel takes place during the end of "The Sound of Drums", where Martha teleports back to Earth with Jack's Vortex Manipulator and witnesses the decimation of London by the Master.
• Martha is four months into her trek when she meets Brigadier Erik Calvin; who had previously worked with UNIT. Brigadier Lethbridge-Stewart is mentioned as well as the Doctor (described as a 'dandy', referring to Jon Pertwee's third Doctor), and the code Martha is given as proof for the Brigadier is "Benton"; a referral to Sergeant Benton, a character who had worked with the Second, Third and Fourth Doctors. It was revealed that Martha had no knowledge of either the Brigadier or Sergeant Benton at this point.
• Martha's perception filter seems to have become faulty at some points; revealing her to the guards in Japan, and even allowing Aleesha to notice her earrings. Nonetheless, the filter prevents the Toclafane from noticing her in "Last of the Time Lords."
• It is revealed that the Earth was seemingly going to be invaded by another alien race by the name of the Drast. They aborted their mission when the Master arrived, as they knew they would not be able to match his power. This led to the death of Japan, as the Master discovered the Drast's appearance on Earth. Martha narrowly escaped being killed along with the country by skipping out on a boat. (In "Last of the Time Lords," Tom Milligan tells Martha that the stories say she was the only one to escape Japan alive, hinting at these events)
