Dirk Gently's Holistic Detective Agency

Douglas Adams' Dirk Gently's Holistic Detective Agency is undeniably a cult classic. It is also, in the immortal words of the author himself, a 'thumping good detective-ghost-horror-who dunnit-time travel-romantic-musical-comedy-epic'. You don't get much more holistic than that. Along with the equally surreal sequel, The Long Dark Tea Time of the Soul, (which co-stars Thor, God of Thunder, God of Rain, God of the High Towering Clouds, God of - you get the picture) Douglas Adams' answer to Sherlock Holmes has perplexed and delighted readers for decades. Fans of Terry Pratchett, Jasper Fforde, PG Wodehouse and of course the Hitchhiker's Guide to the Galaxy series will revel in the warmth and whimsical humour of these novels - which have spawned not one, but two TV series.
