No blurb on back cover. Blurb on inner dustjacket flaps as follows:
On a peaceful rural planet, where the colourful pageantry of old Ruritania mingles with ultra-modern Android technology, the Doctor becomes a king-maker in spite of himself.
In his search for another segment of the Key to Time the Doctor matches wits and swords with the evil Count Grendel — aided, of course, by Romana and the invaluable K9.
