The continuing adventures of Henry Gordon Jago and George Litefoot, characters first introduced on television in Doctor Who: The Talons of Weng-Chiang (1977), who have become Infernal Investigators, solving mysteries involving paranormal or alien phenomena in 1880s London.

It's 1812, and the Doctor, Steven and Dodo get ready to spend their winter in a Russian village. The French are on their way, but that's not the only invasion the travellers will have to deal with. Written by: Marc Platt. Directed by: Nigel Fairs.

Professor Litefoot and Henry Gordon Jago are accustomed to the murky fog of Victorian London and the palatable pints of half and half at the Red Tavern. They are not used to travelling through time and space with their old friend the Doctor. And now they find themselves whisked off to the planet Venus in the distant future, at a time when warrior women rule from a floating city in the clouds. There’s a mystery here, one that the Grand Empress Vulpina intends to keep secret. Even if it means destroying these visitors from the long-dead planet Earth....

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.

On the isolated planet of Indigo 3, far out in the wastes of the Blue Desert, lies the Sanctuary of Imperfect Symmetry. It is a place of contemplation and reflection. It is also a place of death. Something from another time, from another world, has found its way inside the hallowed walls. Something with a leathery hide, a long snout and sharp, pointy teeth.

Stepping out of the Tardis into Victorian London, Leela and the Doctor are confronted by menacing, diabolical horrors shrouded within the swirling London fog - a man's death cry, an attack by Chinese Tong hatchet men, giant rats roaming the sewers, young women mysteriously disappearing... The hideously deformed Magnus Greel, conducting a desperate search for the lost Time Cabinet, is the instigator of all this evil. Posing as the Chinese god Weng-Chiang, Greel uses the crafty Chang, and the midget manikin Mr Sin to achieve his terrifying objectives.

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.

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

'Prison in Space' by Dick Sharples, adapted by Simon Guerrier: A relaxing break for the Doctor and his companions Jamie and Zoe becomes something decidedly more sinister when they are arrested for trespassing. But what has happened to the planet Earth? And how has the malevolent Chairman Babs gained control? As the Doctor and Jamie are incarcerated in a prison that they can never escape from, Zoe is forced to change sides....

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. The police are baffled, the public enamoured...but Professor George Litefoot and Henry Gordon Jago are on the case. Or at least they will be when they've finished their beer. What is the source of The Pugilist's spectacular supernatural powers? Is he alone in his noble quest?

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?

Patrick Troughton, Jon Pertwee and Tom Baker star as the Doctor in these seven narrated full-cast TV soundtracks of classic Doctor Who TV serials.

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?

Business as usual? Not at Hulbert Logistics, where staff are facing a menace far worse than the prospect of the office Christmas party. Lucie’s made some new friends and the Doctor’s met some old enemies. But just who will become the Headhunter’s new apprentice? Welcome to the job interview from hell. Note: This adventure continues from Doctor Who: Human Resources Part 1

Lucie Miller's been headhunted to join the staff of Hulbert Logistics, a respectable blue-chip firm in Telford. Great prospects, competitive salary - you don't have to be mad to work here! But wasn't she made for better things, like travelling by TARDIS through time and space? The Doctor, meanwhile, has been fired - into a confrontation with the most terrifying of enemies....
