Dirk Gently's Holistic Detective Agency by Douglas Adams, author of The Hitchhiker's Guide to the Galaxy, is a much-loved cult classic, that has spawned radio dramas, television, theatre and comic book adaptations across the globe.

What do a dead cat, a computer whiz-kid, an Electric Monk who believes the world is pink, quantum mechanics, a Chronologist over two hundred years old, Samuel Taylor Coleridge (poet), and pizza have in common?

Apparently not much; until Dirk Gently, self-styled private investigator, sets out to prove the fundamental interconnectedness of all things by solving a mysterious murder, assisting a mysterious professor, unravelling a mysterious mystery, and eating a lot of pizza - not to mention saving the entire human race from extinction along the way (at no extra charge).
