First paperback edition. Novelization of the 6-episode 1968 storyline, with Pemberton adapting his own teleplay. Due to the 192-page book having a much higher than usual page count than the usual 128-144 page Target novelization, the cover promotes it as "a bumper volume". No. 110 in the Doctor Who Library.
