Re: I'm touched by the weirdness of this request...
"I would recommend "Dirk Gently's Holistic Detective Agency" and possibly "The Long, Dark Teatime of the Soul" (not as good) by Douglas Adams"
And I would thoroughly recommend _avoiding_ the TV serialisations of Dirk Gently. DNA was a brilliant TV scriptwriter but whoever turned these into TV programs wasn't (HHGTTG TV and movies were both brilliant because DNA had his hand on the directors' throats.)
