The Hitchhiker's Guide to the Galaxy: the complete story of all five books, from the bulldozer on a Thursday morning to the last page of Mostly Harmless — and the missing question behind 42.

Everybody knows the answer is 42. Almost nobody knows the question — and that is the joke Douglas Adams spent thirteen years and five novels refusing to resolve.

This is the full story of The Hitchhiker's Guide to the Galaxy, told for someone who has never opened one of the books, and for readers who want the whole shape of the series laid out end to end. We follow Arthur Dent from the mud in front of a bulldozer in the West Country to the job of village Sandwich Maker on a quiet planet far from anywhere, with every major idea, joke and reveal in between.

Covered in this video:

• Book 1, The Hitchhiker's Guide to the Galaxy (1979) — the bypass, the Vogon demolition order, the Babel fish, Vogon poetry, the Infinite Improbability Drive, the whale and the bowl of petunias, Slartibartfast and the fjords, Deep Thought, and the reveal of what the Earth actually was.
• Book 2, The Restaurant at the End of the Universe (1980) — who really paid the Vogons, the cup of tea that nearly destroyed the Heart of Gold, the Total Perspective Vortex, Milliways, the Golgafrinchan B-Ark, and the Scrabble tiles that spell out a broken question.
• Book 3, Life, the Universe and Everything (1982) — Wowbagger, the Ashes, the Krikkit Wars, Agrajag, how Arthur Dent learns to fly, the prophecy of Stavromula Beta, and Hactar's conscience.
• Book 4, So Long, and Thanks for All the Fish (1984) — the restored Earth, the dolphins' farewell, Fenchurch, Wonko the Sane, the rain god, and God's Final Message to His Creation.
• Book 5, Mostly Harmless (1992) — plural zones, the Guide Mark II, Random Dent, Tricia McMillan, the Grebulons, and the ending Adams himself called bleak.

Along the way: the real story of why Douglas Adams picked 42 (and what he said about base 13), the field near Innsbruck, the 1978 BBC Radio 4 series, the Infocom text adventure, the 2005 film additions, Towel Day, the puddle analogy, and what "Don't Panic" actually means as advice.

Characters covered: Arthur Dent, Ford Prefect, Zaphod Beeblebrox, Trillian, Marvin the Paranoid Android, Slartibartfast, Deep Thought, Fenchurch, Random Dent, Prostetnic Vogon Jeltz and Agrajag.

If you enjoy long-form science fiction lore and full book series breakdowns, subscribe — and tell me in the comments: is Mostly Harmless the honest ending, or should the series have stopped at book four?

Like, comment and share if this made you want to reread them. Always know where your towel is.
