Dirk Gently’s Holistic Detective Agency began as a book (or two) by Douglas Adams. Not as well known as the Hitchhiker’s series, which I think is a shame. They have the same absurd humour, but with tighter, cleverer plots. Dirk Gently, a detective who refuses to ‘eliminate the impossible,’ solves crimes by looking for connections between seemingly unconnected events and objects. Against all likelihood (and despite his seeming incompetence), he succeeds in unravelling a supernatural mystery and foiling whoever was threatening the world. If I did have a complaint about the book, it’s that it took me too long to get the resolution in The Long Dark Tea-time of the Soul. I felt that too much was implied. (That could just be me being slow, of course.)
