After having read Adams's 'Hitchhiker' series, I then wished to read the recently published posthumous compilation of his works, 'The Salmon of Doubt'. Yet after viewing the back of that particular book, I realised that I would benefit from reading his two preceding Dirk Gently novels beforehand. The first, 'Dirk Gently's Holistic Detective Agency', is hilariously written, with characters that compliment each other perfectly. Dirk Gently himself outranks Sherlock Holmes and Dick Tracy, in every manner but conventionality of methods, and it is his theory of the 'interconnectedness' of all things that gives the entire novel its sharp and refreshing originality. If read over a prolonged period, the ending may prove a little confusing; but if closely followed, the intelligent climax will be appreciated. Read this book, then read the others!
