Deep Blue (novel)
Deep Blue is a BBC Books original novel written by Mark Morris and based on the long-running British science fiction television series Doctor Who. It features the Fifth Doctor, Tegan, Turlough, and members of UNIT, mostly embodied by Captain Mike Yates.Placement
As a Fifth Doctor novel set in the Third Doctor's era, Deep Blue is notable for possessing a particularly complex chronology. To minimize confusion with later meetings between the Fifth Doctor and Brigadier Lethbridge-Stewart, Mike Yates, someone who never met the Fifth Doctor on screen, is used as the main UNIT contact. One of the chief points of interest in the work is how the Brigadier, Turlough and Tegan can appear together, both long before — and long after — they apparently met for the first time in Mawdryn Undead.
