Mesopotamia—the cradle of civilization. In the fertile crescent of land on the banks of the rivers Tigris and Euphrates, mankind is turning from hunter gatherer into farmer, and from farmer into city-dweller. Gilgamesh, the first hero-king, rules the city of Uruk. An equally legendary figure arrives, in a police telephone box: the TARDIS has brought the Doctor and his companion Ace to witness the first steps of mankind's long progress to the stars. And from somewhere amid those distant points of light an evil sentience has tumbled. To her followers in the city of Kish she is known as Ishtar the goddess; to the Doctor’s forebears on ancient Gallifrey she was a mythical terror—the Timewyrm.

The pursuit of the Timewyrm leads the Doctor and Ace to London, 1951, and the Festival of Britain—a celebration of the achievements of this small country, this insignificant corner of the glorious Thousand Year Reich. Someone—or something—has been interfering with the time lines, and in order to investigate, the Doctor travels further back in time to the very dawn of the Nazi evil. In the heart of the Germany of the Third Reich, he finds that this little band of thugs and misfits did not take over half the world unaided. History must be restored to its proper course, and in his attempt to repair the time lines, the Doctor faces the most terrible dilemma he has ever known...

The end of the Universe. The end of everything. The TARDIS has tracked the Timewyrm to the edge of the Universe and the end of time—to the lush planet Kirith, a paradise inhabited by a physically perfect race. Ace is not impressed. Kirith has all the appeal of a wet weekend in Margate, and its inhabitants look like third-rate Aussie soap stars. The Doctor is troubled, too: If the Timewyrm is here, why can’t he find her? Why have the elite Panjistri lied consistently to the Kirithons they govern? And is it possible that the catastrophe that he feels impending is the result of his own past actions?

Fourth and final book in the Timewyrm series. The parishioners of Cheldon Bonniface walk to church on the Sunday before Christmas, 1992. Snow is in the air, or is it the threat of something else? The Reverend Trelaw has a premonition too, and discusses it with the spirit that inhabits his church. Perhaps the Doctor is about to visit them again? Some years earlier, in a playground in Perivale, Chad Boyle picks up a half-brick. He's going to get that creepy kid Dorothy who says she wants to be an astronaut. The weapon falls, splitting Dorothy's skull. She dies instantly. The Doctor pursued the Timewyrm from prehistoric Mesopotamia to Nazi Germany, and then tot he end of the universe. He has tracked down the creature again: but what transtemporal trap has the Timewyrm prepared for their final confrontation? An original Doctor Who novel. Full length science fiction novels; stories too broad and too deep for the small screen.
