How would you describe the content of the book and your writing style?

Essentially, the book takes each story of Series 5 as a chapter in its own right where in roughly three, maybe, four sections I review the relevant episodes and look at the series's character development, major themes, the use of design and music, references to previous episodes and the original series. The spine of each chapter is about themes and characters and that's where a lot of the research is included. So, I will bring in cultural, literary, political, sociological and psychoanalytical material to inform my views of the episode. Crucially, this is just one person's view and as I say in the introduction it is not intended to be an essentialist one. I am aware that a lot of references, particularly around cultural politics, might alienate some fans and with that in mind I've attempted to pitch the book at a level that is accessible to all. Anyone who is interested in what the episodes mean on many different levels will I hope find the book fascinating.

Time Hunter: The Severed Man

What links a clutch of sinister murders in Victorian London, an angel appearing in a Staffordshire village in the 1920s and a small boy running loose around the capital in 1950?

When Honoré and Emily encounter a man who appears to have been cut out of time, they think they have the answer. But soon enough they discover that the mystery is only just beginning and that nightmares can turn into reality.

Part mystery, part detective story, part dark fantasy, part science fiction... original adventures in time and space.

We expect to perform very well this Christmas, our sales so far are better than last year. This is mainly down to our good product range. We expect the Doctor Who, ZhuZhu and Armed Forces Collection brands to be our best-sellers.

Shadows of the Vashta Nerada

Kicking off immediately after the cliff-hanger ending of episode three, the latest Adventure Game picks up the story of the Doctor and Amy who've materialised just south of London (and about a 1000 miles to the left), inside a sea-bed colony called Poseidon. Shadows of the Vashta Nerada features a cracking plot which surrounds a real-world conspiracy and, of course, it takes place at Christmas.

Steven Moffat, executive producer and lead writer for Doctor Who: "We've gone all-out for the season finale. Shadows of the Vashta Nerada takes place entirely underwater - something which would be impossible for the TV series, as water is so expensive. It's thrilling, terrifying, educational and fun. Just steer clear of those shadows..."

Earthling Jeff Spooner accepts an offer to explore the galaxy with his barber, Ray Scump. The pair are thrown into a non-stop adventure as they embark on a quest to find the fabled Universal Remote – avoiding danger, doom and embarrassing situations as they go.

Aided by two badly-programmed robots and an army of warrior spacehoppers, our heroes duck, dive and try to dodge the biggest threats in the galaxy: Overlord Kelvin of Skragg, the terminally dreary Emo people and Queen Shelley – a bald, cannibalistic Amazon who has a score to settle from way back...

In the lead up to this year's Christmas Special, Doctor Who: A Christmas Carol, airing on BBC AMERICA — the BBC is developing a brand new action adventure puzzle app to be available for the iPhone, iPod Touch and iPad.

It's the deepest part of winter, the exact midpoint, Christmas Eve – halfway out of the dark. Amy and Rory are trapped on a stricken space liner that's plummeting through banks of thick icy fog to the surface of the planet below.

Only one man has the power to save them; only one man is in possession of a machine that can clear the fog and let them land safely.

That man is Kazran Sardick, a rich but lonely old miser who rules Sardicktown with a sky-mast of iron.

The Doctor's only chance of rescuing the ship's four thousand passengers is to save Kazran's soul and show him that life is worth living. For this he needs to go back, way back, to when Kazran was a boy with a life full of promise.

But can the Doctor put a song in Kazran's heart and love in his life, in time for Christmas? Can he bring him out of the dark?

I've always wanted to be part of the Christmas Doctor Who experience, and I think this is certainly one of the most Christmassy and inventive Doctor Who stories so far. Steven just keeps getting even more imaginative and the great thing about this episode is that when Doctor Who and Christmas are put together you combine the spirit of both those things; it's a fun old yarn and the Doctor simply loves Christmas.

It was a real privilege to work with Michael (Gambon). I had a great time with him and he was really naughty! He's so crafty and when I asked him about working with iconic actors such as Olivier and Bates he said the one thing they all had in common was they were naughty – and he's exactly the same. He was very mischievous, constantly telling jokes and getting into the spirit of play.

With Katherine I was astounded by her professionalism. Considering it was her first acting experience I thought she handled it with real craft and diligence. It's exactly the type of casting we want; someone fresh, exciting and new."

I had the most amazing time; I must admit I was very nervous and I felt out of my comfort zone because I hadn't done any acting before. However, when I arrived on set the whole team was so welcoming and supportive. They made me feel like I could do it. It certainly felt very Christmassy when we were filming it in July! The story is very emotional which I hope is going to touch people.

I do get to sing though which was nice and I had a really good laugh with Matt between takes. He kept mucking around and singing to me but you know people should hear his voice; I think he's got a great bass voice!

Oh, we're going for broke with this one. It's all your favourite Christmas movies at once, in an hour, with monsters. And the Doctor. And a honeymoon. And... oh, you'll see. I've honestly never been so excited about writing anything. I was laughing madly as I typed along to Christmas songs in April. My neighbours loved it so much they all moved away and set up a website demanding my execution. But I'm fairly sure they did it ironically.

Matt Smith and Karen Gillan captivated audiences in their debut series, and Doctor Who's clever twist on the much loved A Christmas Carol will thrill BBC One viewers this year with special guest stars Sir Michael Gambon and singing sensation Katherine Jenkins joining Amy and the Doctor for an unforgettable present!
