Gallifrey is in a state of crisis, facing destruction at the hands of an overwhelming enemy. And the Doctor is involved in three different incarnations - each caught up in a deadly adventure, scattered across time and space. The web of time is threatened - and someone wants the Doctor dead. The three incarnations of the Doctor must join together to set time back on the right track - but in doing so, will they unleash a still greater threat?

The Great Time War has raged for centuries, ravaging the universe. Scores of human colony planets are now overrun by Dalek occupation forces. A weary, angry Doctor leads a flotilla of Battle TARDISes against the Dalek stronghold but in the midst of the carnage, the Doctor's TARDIS crashes to a planet below: Moldox. As the Doctor is trapped in an apocalyptic landscape, Dalek patrols roam amongst the wreckage, rounding up the remaining civilians.

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?

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.

Twas the night before Christmas, and all through the house not a creature was stirring.... But something must be stirring. Something hidden in the shadows. Something which kills the servants of an old Edwardian mansion in the most brutal and macabre manner possible. Exactly on the chiming of the hour, every hour, as the grandfather clock ticks on towards midnight. 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.

The human race is locked in deadly combat with the android hordes in the Orion System. Light-years from the front line, the Doctor and Charley arrive to sample the dubious delights of a galactic backwater, little suspecting that the consequences of the Orion War might reach them there. But High Command's lust for victory knows no bounds.

When the Doctor and Donna visit London's Technology Museum for a glimpse into the future, things don't go to plan. The most brilliant IT brain in the country can't use her computer. More worrying, the exhibits are attacking the visitors, while outside, people seem to be losing control of the technology that runs their lives. Is it all down to simple human stupidity, or is something more sinister going on?

An excellent jumping-on point for new listeners... Paul McGann's Eighth Doctor starts another phase of his adventures with a brand new companion (Lucie Miller - played by the award-winning Sheridan Smith) and an all-star supporting cast. Originally broadcast on BBC Radio 7.

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.

On a dark, frozen planet where no planet should be, in a doomed city with a sky of stone, the last denizens of Earth's long-lost twin will pay any price to survive, even if the laser scalpels cost them their love and hate and humanity. And in the mat-infested streets, around teatime, the Doctor and Nyssa unearth a black market in secondhand body parts and run the gauntlet of augmented police and their augmented horses.

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 Doctor has always admired the work of William Shakespeare. So he is a little surprised that Charley doesn't hold the galaxy's greatest playwright in the same esteem. In fact she's never heard of him. Which the Doctor thinks is quite improbable. General Mariah Learman, ruling Britain after the Eurowars, is one of Shakespeare's greatest admirers, and is convinced her time machine will enable her to see the plays' original performances. Which the Doctor believes is extremely unlikely.

An epic adventure uniting the Doctor's friends across time and space, featuring Jago & Litefoot, Counter-Measures, the Vault and Gallifrey!

At the heart of it all is a terrible secret, almost as old as the Time Lords themselves.

Hallowe'en 1938. A year after a mysterious meteorite lit up the skies of New York State, Martian invaders laid waste to the nation. At least, according to soon-to-be infamous Orson Welles they did. But what if some of the panicked listeners to the legendary War of the Worlds broadcast weren't just imagining things? Attempting to deliver Charley to her rendezvous in Singapore in 1930, the Doctor overshoots a little, arriving in Manhattan just in time to find a dead private detective.

They call him The Pugilist. It is the dawn of a new century and a vigilante is on the loose. The scourge of the criminal underclass. The saviour of the virtuous and the protector of the weak.
