On New Year's Eve, 1930, the Doctor lets Charley keep her appointment at the Raffles Hotel in Singapore. But his unease at what he's done to time by saving her life soon turns into fear. Sebastian Grayle: immortal, obsessed, ruthless, has come to the city to meet the Time Lord. To the Doctor, he's a complete stranger, but to Grayle, the Doctor is an old enemy. An enemy that, many years ago, he finally succeeded in killing. And this is his only chance to gloat.

The universe stands on the brink of a dimensional crisis - and the Doctor and Raine are pulled into the very epicentre of it. Meanwhile, on Earth, UNIT scientific advisor Dr Elizabeth Klein and an incarnation of the Doctor she's never encountered before are tested to the limit by a series of bizarre, alien invasions. At the heart of it all is a terrible secret, almost as old as the Time Lords themselves.

The Doctor and Charley decide to take a well-deserved break from the monotony of being chased, shot at and generally suffering antisocial behaviour at the hands of others. And so they end up in Venice, well into Charley's future, as the great city prepares to sink beneath the water for the last time...which would be a momentous, if rather dispiriting, event to witness in itself.

Trapped and afraid, the Doctor and Charley are forced to play detective to murders with no motive, where even the victims don't stay dead.

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?

Britain. The height of the Roman occupation. The Doctor has brought Leela to ancient Norfolk to learn about her ancestors...but has no idea how much of an education she is going to get.

As Leela begins to be swayed by the warrior queen's words, the Doctor has to make a decision: save his friend...or save history itself?

An excellent jumping-on point for new listeners....

Originally broadcast on BBC Radio 7.... 'The crashed ship. The one Tom Cardwell saw all those years ago. And you borrowed its technology, didn't you? Maybe even found a Dalek or two in the wreckage. Dead but intact. And you began to turn human beings into creatures like them.'
