The 1996 Virgin Missing Adventures novel The Scales of Injustice by Gary Russell also explores the events surrounding Liz's resignation from UNIT. Liz additionally appears with UNIT in the Missing Adventures novel The Eye of the Giant (1996) and the Past Doctor Adventures novel The Devil Goblins from Neptune (1997). Scales of Injustice directly acknowledges that Liz left UNIT because she felt surplus to requirements with the Doctor around and wanted to focus more on scientific research, the Doctor assuring her that he understood her reasons and regretted that they hadn't been able to spend more time together as friends. Liz eventually does travel in the TARDIS with the Third Doctor and Jo Grant in the Past Doctor Adventures novel The Wages of Sin (1999), which takes place after the Doctor regains his freedom, with the Doctor's attempt to take her to witness the Tunguska Event accidentally resulting in them becoming caught up in the truth about the death of Grigori Rasputin. A parallel version of her appears in the novel Blood Heat where she is still part of UNIT fighting against the Silurians in a world where the Doctor died before defeating the reptiles. According to the 1997 Virgin New Adventures novel Eternity Weeps by Jim Mortimore, Liz dies in 2003, the victim of an extraterrestrial terraforming virus contracted while she was part of a UNIT team investigating an alien artefact on the Moon, despite the efforts of the Seventh Doctor and his current companion Chris Cwej to save her.
