Note: At least two printings of this paperback sported two different ISBNs - the one above on the back cover but 0-426-20103-5 on the inside copyright page. Neither ISBN belongs to another book, so it is impossible to tell which is the "right" one.
The Doctor and Romana had successfully retrieved five of the segments and now they have reached the planet Atrios in the middle of an atomic war, to search for the last, most vital piece.
Sinister dangers await them in this final stage of their quest...
Note: This was the last UK hardback novelisation to have a removable dustjacket — all future hardbacks from WH Allen (from The Curse of Peladon onwards) had laminated covers, i.e. the artwork was actually part of the cover.
Unending atomic war, a vanishing planet and the sinister power of the Shadow, Master of Evil...
All these dangers and more stand between Romana and the Doctor and the last, most vital segment of the Key to Time.
Even at the moment of apparent victory the last, most terrifying peril still awaits them...
