Ten stories - Seven Doctors - One enigma

Los Angeles. The war's over, the GIs are home, Truman's in the White House and the mobsters are making a killing - as usual. Into the office of a private investigator walks a mysterious little man with a story that's out of this world. He says he's lost his memory. He wants the PI to help him. When he turns out his pockets, he produces a pile of bizarre objects, each of which restores a memory and solves a part of the puzzle.

And the memories seem to belong to seven different people.

Decalog is a new concept in Doctor Who fiction: A cycle of ten linked stories. The stories are written by authors who are well known to readers of the New Adventures or Doctor Who magazines - Paul Cornell, Marc Platt, Vanessa Bishop, Jim Mortimore, Andy Lane - and have been brought together by Mark Stammers and Stephen James Walker, who are part of the team that researches and writes in-depth factual books about Doctor Who such as The Sixties and the Handbook series.

ETERNITY WEEPS

The Doctor and Chris are called in to a situation fast getting out of control, as countless numbers flee a biological terror.  The world is about to undergo a new genesis.  While Chris gets himself a job with NASA, the Doctor must unravel the ties between Mount Ararat, the moon, and an ancient exedus.

Mankind faces apocalypse.  But can the aid of a far older race, alongside companions past and present, prevent the planet being twisted into the image of a long-dead world?

THE NEW ADVENTURES

JIM MORTIMORE lives in Bristol, and has reluctantly agreed to the removal of all jokes from this biog.

Easter Island, 1842.  Horace Stockwood, eminent archaeologist, has stolen a stone tablet sacred to the islanders.  He escapes into the open sea, but massive, sinister stone figures are lining the cliff tops, watching him go…

Thirty years later, Stockwood is desperate to return.  He has devoted his life to studying the sacred stone, and needs to know if his theories are correct.  Visiting Earth with Leela, the Doctor's interest is piqued, and he offers to fund Stockwoods expedition.  But their journey proves more hazardous than anyone would have expected.

What is the terrible secret that pushes Stockwood on - and what is his real agenda?  Who is trying to stop their mission before it has even begun?  As the Doctor begins to piece the answers together, it seems he may become an unwitting accomplice to the terrible tragedy that threatens to befall the island.  Ancient powers are invoked, and dangerous secrets may soon be secret no longer...

'If I'd wanted to spend the rest of my life hoofing it around grimy spaceships for no good reason I'd have stayed in Spacefleet.'

Ace is back. And she's not in a good mood.

Bernice has asked the Doctor to bring the TARDIS to the planet Lucifer, site of a scientific expedition. It's history to her: the exploration of alien artifacts on Lucifer came to an abrupt halt three centuries before she was born, and she's always wondered why.

Uncovering the answer involves the Doctor, Bernice and Ace in sabotage, murder, and the resurrection of eons-old alien powers.

Are there Angels on Lucifer? And what does it all have to do with Ace?

Full-length, original novels based on the longest-running science fiction television series of all time, the BBC's Doctor Who.  The New Adventures take the TARDIS into previously unexplored realms of space and time.

'Change, Benny. It's the most terrifying thing of all.'
'And that's what's happening to you, is it, Doctor?'
'It's what's happening to all of us.'

The TARDIS has arrived in the Elysium system, lost colony of distant Earth and site of the Artifact: a world turned inside out, a world of horrific secrets.

For more than a century scientists have studied the ecosystem flourishing within the Artifact. Now the system is in collapse and even the humans trapped inside are changing into something new and strange.

With the members of one expedition murdered, those of another fighting for their lives and a solar system on the brink of civil war, can the Doctor, Ace and Benny survive a journey to the heart of the Artifact in their search for the truth?

'I'm sure the Beach Boys didn't have mutant elephants in mind when they wrote "Surfin' USA.".'

When Bernice Summerfield finds human skull fragments containing her own DNA in the stomach of a mummified dinosaur, she embarks on a trail of murder and betrayal. From the alien jungles of France to the primal continent of Pangaea, the trail leads ever further back in time. Together with Patience, the cloned smart-raptor, Benny must brave alien hybrids, agents of the Knights Templar guarding a secret older than time - and have breakfast with the man who would be Emperor of Earth.

All to find the fabled Sword of Forever, a mythical device with the power to destroy and create civilisations - but at what price?

Everything goes critical as Bernice and Patience travel across 120 million years and two universes - where ancient traps guard crumbling ruins, love is unrequited, time is running out, treasure is always buried and X never fails to mark the spot.
