We have been waiting for months, and now it's official : BBC Radio 4, which has broadcasted all the Hitchhiker's radio series from the first episode in 1978, have commissioned Dirk Maggs and Above The Tittle to make a 18 episodes radio adaptation of the Dirk Gently books. There will be three series (with 6 episodes each) and the broadcasting will begin in next october.
I can't tell you how happy I am. Dirk Maggs has made an incredible work with the last three series of Hitchhiker's and will certainly make some wonderful work with Dirk.
I think that the Dirk Gently series will include the unfinished book "salmon of doubt" as there are three series, and maybe Dirk will write the end of the story, but i'm not sure right now.
