Publisher's summary
In a small mining colony on the dark and distant planet of Lethe, strange events are occurring -- the results of which could dramatically affect things on a universal scale. For within the dingy corridors of the artificial biosphere, the lone survivor of a devastating crash has expertly wormed his way into the lives of the colony's personnel.

A scientist known as Davros.

Separated from one another across space and time, the Doctor and Mel find themselves in very different predicaments: Mel has been employed on Lethe, while the Doctor has been imprisoned aboard an alien spacecraft. Both situations are inexorably linked, however, and at the apex of the two sits Davros and the terrifying possibility of a new threat even more powerful than the Daleks!

Rescuing Mel and stopping Davros should be the Doctor's primary goals, but could it be that this time, Mel does not wish to be rescued? And might Davros actually be working on something for the benefit of the civilised galaxies...?

 * Geoff has feelings for Mel. He was previously attracted to Sonali but she rejected his advances.
 * Prior to her arrival on Lethe, the only computer languages at which Mel was adept were BASIC, COBOL and FORTRAN.
 * Professor Vaso is, in actuality, Davros.
 * The ship carrying Davros to Skaro was attacked in the Beta Orianus system and was presumed to have destroyed with all hands. However, the Daleks later discovered that it crashed on Lethe and Davros survived. After adopting the identity of Professor Vaso, Davros claimed that his physical status as a result of injuries sustained in the crash.
