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.

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.

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.

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 Doctor and Charley travel to the remote Cimmerian System to unravel the mystery of its sun. But darkness has already embraced the scientific base on Cimmeria IV in more ways than one. In a fight for survival, the Doctor must use all his wits against a deadly artificial lifeform and an ancient race whose return to the Cimmerian System threatens suffering and death on an apocalyptic scale. Written and directed by Nicholas Briggs.

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.

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 Doctor and Lucie go glam when the Tardis makes an unexpected landing in 1974. Slade, The Sweet and Suzi Quatro are Top of the Pops - and brother-and-sister duo The Tomorrow Twins will soon be joining them, if the star-making Svengali Arnold Korns has his way. But will their dreams turn to dust at a service station somewhere on the M62, besieged by a pack of alien monsters?

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 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.'
