A short but witty novel about the interconnectedness of all things and the somewhat mad Dirk Gently who uses this system to solve crime and con his way out of paying the bills.
This book is itself an example of the elemental concept upon which it is based. The first several chapters are seemingly unrelated but quickly resolve themselves into a single and cohesive whole.
The book is hilarious in the style which no-one but Douglas Adams would ever be able to replicate. The humour is unique but brimming and the sci-fi elements are subtle enough that most anyone could relate to them but definately present for the enthusiast.
Dirk Gently's Holistic Detective Agency, like other of Adams' books that I've read was written purely for pleasure and I thoroughly enjoyed the process. It was so easy to read I managed in a day.
On a side note I promise I'll try and read more of these soon and get up to date, it's nearly the summer and then I'll have much more free time.
