Terrance Dicks Novel Adaptation For Series 6?

I recieved an email about 30 minutes ago from someone who is usually really reliable, stating that they are adapting Terrance Dicks Seventh Doctor novel, Blood Harvest, for series 6, probably the latter half.

It claimed that the filming of the adaptation will tie in with the supposed US filming, possibly in Chicago.

If you arent familiar with Terrance Dicks, then shame on you! He was one of the main reasons Doctor Who became what it is today. And if you arent familiar with Blood Harvest, this is a synopsis.

'Doc's peddling bootleg liquor in an illegal speakeasy. You’re carrying a gun for him, Ace - which makes you no better than any other gun-moll.'

Dekker is a private eye; an honest one. But when Al Capone hires him to investigate a new joint called ‘Doc’s’, he knows this is one job he can’t refuse. And just why are the Doctor and Ace selling illegal booze in a town full of murderous gangsters?

Meanwhile, Bernice has been abandoned on a vampire-infested planet outside normal space. There she meets a mysterious stranger called Romanadvoratrelundar -- and discovers an ancient and malevolent power, linking 1929 Chicago with a lair of immortal evil. The consequences of this story are inextricably linked to events in the Doctor’s past.

This also ties in with the speculation of more vampires in series 6.

Other stories in recent series that have been adapted are The Lodger and Human Nature/Family of Blood.

As always guys, treat this as speculation until we know something more concrete.
