Zagreus sits inside your head. Zagreus lives among the dead. Zagreus sees you in your bed and eats you when you're sleeping....
October 1930. His Majesty's airship, the R101, sets off on her maiden voyage to the farthest-flung reaches of the British Empire, carrying the brightest lights of the imperial fleet. Carrying the hopes and dreams of a breathless nation. Not to mention a ruthless spy with a top-secret mission, a mysterious passenger who appears nowhere on the crew list, a would-be adventuress destined for the Singapore Hilton...and a Time Lord from the planet Gallifrey.
The legend dates back to Roman times, at least: a great White Worm, as wide as a man, slithers out of the rocks of the Dark Peak Gap to take animals, sometimes even children, for its food. When the Doctor and Leela arrive in the wilds of Derbyshire only to get caught up in the hunt for a missing girl, they soon discover that the legend of the Worm is very much alive - even now, in 1979. Worse still, it seems that the Doctor isn't the only renegade Time Lord on the trail of this deadly and mysterious Worm....
The web of time is stretched to breaking. History is leaking like a sieve. In the Citadel of Gallifrey, the Time Lords fear the end of everything that is, everything that was...everything that will be. The Doctor holds the Time Lords' only hope - but exactly what lengths will the Celestial Intervention Agency go to in their efforts to retrieve something important from within his TARDIS? What has caused Imperiatrix Romanadvoratrelundar to declare war on the rest of creation? And can an old nursery rhyme about a monster called Zagreus really be coming true?
The first time the fearsome Kraals attempted to take over the Earth, with the help of their android agents, things didn't go quite according to plan - thanks to the time-travelling alien Doctor and his allies at UNIT. This time Marshal Grinmal and his belligerent cohorts are ready for them. This time they'll make no mistakes. This time Chief Scientist Tyngworg has not just one plan but a backup plan and a backup backup plan worked out.
Nineteen thirty-five: a message from a Time Lord in trouble sends the Eighth Doctor and Charlotte 'Charley' Pollard to the streets of London's West End, in search of a mysterious alien adversary - unaware that something monstrous is already on their trail. They soon discover that an insidious conspiracy is indeed at work, its tentacles extending the length of the British Isles.
