Theory:Doctor Who prose discontinuity and plot holes/Goth Opera


 * This book apparently occurs "between Snakedance (TV story) and Mawdryn Undead (TV story)". Unfortunately these two stories are consecutive, with the former flowing directly into the latter. (This is actually a problem with many Missing Adventures.)
 * The Mara lurking in Tegan's mind in this book is actually just a mixture of her own paranoia and the trauma of having her mind taken over twice now. Presumably she also has a nightmare or trouble sleeping after the close of this book, which leads into her conversation with the Doctor at the beginning of Mawdryn Undead (TV story). (I'd noticed. Why Planet of Giants (TV story), for example, is considered the best spot for the original TARDIS team is beyond me.)
 * till doesn't work. The conversation at the beginning of Mawdyn Undead makes it clear beyond any ambiguity that Snakedance has just happened.
