The Sixth Doctor continues his travels with Flip and Constance in The Middle.

The latest tale in the Doctor Who Main Range is out now. Colin Baker, Lisa Greenwood and Miranda Raison are in ‘The Middle’ of their trilogy of adventures (see what we did there ?!).

It’s L/Wren Mrs Constance Clarke’s birthday – and Flip is determined to make it an anniversary to remember.†¨†¨

The futuristic colony of Formicia, where the pampered populace pass their days in endless leisure, seems the perfect place for a ‘Wren Party’. But all is not as it seems. Looking down from the Middle, the skyscraping tower that ascends as far as the colony ceiling, Formicia’s overseers can see that the Doctor doesn’t fit in – and it’s not just his coat that makes him conspicuous...†¨†¨

‘The End is the Beginning’, say the propaganda-like posters all over Formicia. Because to be part of this perfect society comes at a price. And the Doctor's already in arrears.

"The idea of The Middle sort of came from two places,” writer Chris Chapman tell us, “the first one is the less silly of the two.

"I had been spending a lot of time with my 94 year old grandfather (now deceased) and had found myself thinking about how formidable and capable his generation was. He'd gone to war, landed on the Normandy beaches in 1944, and even aged 94 he was still driving himself wherever he wanted to go. So that led me to pitching The Middle, a story about ageing, and how you can underestimate the older generation at your peril.

“The second part of the idea, the sillier part, came from a visit to the zoo, and a sign I saw about ants! But I'll let you listen to episode 2 to see how that fits in..."

The next adventure for the Sixth Doctor is the most terrifying tale yet, Static comes out in December.

Deep in the heart of nowhere, near a place called Abbey Marston, there’s a caravan site. The perfect place to get away from it all. Close by, there’s a stone circle they used for human sacrifice in olden times. A little further afield, there’s an old RAF research station, where they did hushhush things in the War.

There’s only one rule: the use of radios, cassette recorders and portable televisions is strictly forbidden.

People come here to get away from it all, you see. No-one wants to hear the noise. No-one wants to hear the voices in the static…

No-one wants to hear the ghosts.
