The Long Dark Tea-Time of the Soul (radio serial)

Starring Harry Enfield, Peter Davison, John Fortune[2] and Stephen Moore, it started broadcasting on 2 October 2008 on BBC Radio 4.

[3] The title is a quotation from the Adams novel Life, The Universe and Everything, where it says of the immortally annoyed Wowbagger:[4] ...it was the Sunday afternoons he couldn't cope with, and that terrible listlessness which starts to set in ... as you stare at the clock the hands will move relentlessly on to four o'clock, and you will enter the long dark teatime of the soul...In adapting the story for six half-hour episodes, Dirk Maggs rescheduled the novel's convoluted plot:[5] The challenge was to retain Douglas's mischievous delight in strewing barrel loads of red herrings across the path of his detective story - all of which prove to be vital clues to its solution...The adaptation is an inverted detective story, shuffling the importance of characters: elevating the Draycotts, turning Neil Sharp into Kate Schechter's landlord and former Pugilism and the Third Autistic Cuckoo member with the now returned Richard MacDuff.

[6] On the audio trailer,[7] Susan Way sells Way Forward Technologies to Sirius Cybernetics, Richard MacDuff is detained by the Vogon catchphrase "resistance is useless", and the I-Ching Calculator has the 'Guide activation' sound, and is obtained from Nobby.

On Douglas's hard drive a sub-folder marked "The Old Salmon" contains a document named "The Whole Resource (Relevant)", forty-three pages of his earliest notes ... quite a few ... feature characters .. from his previous magnum opus [The Hitchhiker's Guide to the Galaxy] ... these have informed ... passages in these recordings, and ... the [now cancelled] third radio series next year.Examples of updating to bring the story into the 21st century (the book was written in the 1980s) include the explosion now being at Heathrow Terminal 5 (with a new joke about lost luggage), this now being explained as "freak indoor Global Warming", various price increases, the introduction of mobile phones, e.g. text messages replacing telegrams, a discussion about only audio purists still using gramophones and the removal of American Kate's frustration at the unavailability of pizza delivery in the UK (now thankfully ancient history).

Episode 4 contains a telephone conversation where Richard MacDuff explains to Dirk that the motherboard of the I-Ching calculator was rubbish and is better put to use as an ultimate talking multi-media hand-held device.
