Funny Cx2, I've never come across dramatizations of Derk Gently myself, i'll have to look int those.
The Derk Gently novels are about a rather odd detective who solves very weerd mysteries. I must admit I'm less keen on them plot wise than the hitch hiker books, though they are well worth reading just for Adams' own writing, ---- as in fact is his documentary about endangered species, last chance to see.
Btw, did you also know he was script editer for the bbc and actually produced several doctor who stories involving the 4th doctor? maybe that was why Tom baker was so loopy.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
