Susan Jameson reads a brand-new original story featuring the Fourth Doctor and his companion Mrs Wibbsey. In 18th Century coastal Italy, the local fishermen haul in an extraordinary catch: a gigantic serpent. The Doctor identifies it as an alien, but to the ailing locals this fabled sea creature has the capacity to heal them - if only Count Otto will share it with them. When Mrs Wibbsey comes under the influence of the Count, the Doctor finds himself snared by the wicked power of a seemingly immortal magician, the infamous Cagliostro!

Hired assassin Doom is on a mission to save her own life before Death catches up with her. If she can find the Doctor they might be able to help her - but where in Time and Space are they? These four missions take Doom to a Mediterranean cruise ship in 1966, the planet Mars in the distant past, San Francisco in 1999, and finally a desolate planet in a dying solar system. Along the way she meets former TARDIS travellers Ian and Barbara, the mighty Ice Warriors, and Brian the Ood. But when a mysterious stranger with silver hair and sunglasses turns up, will he be Doom's salvation?

The TARDIS crewmembers have taken a break from their adventures and are enjoying a rest in a luxury villa. But, in the gory grandeur that is Imperial Rome, things don't stay quiet. If the time travellers can save themselves from being sold as slaves, assassinated by classical hit-men, poisoned by the evil Locusta, thrown to the lions, maimed in the arena and drowned in a shipwreck, they still have to face the diabolical might of the mad Emperor Nero. As if that wasn't enough, they also discover that, although Rome wasn't built in a day, it burnt down in considerably less time.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

Ashley Perrin is fresh out of college and starting a job as a community liaison for the Third District–the city’s only sector with more alien residents than humans.
