Our teenage hero, having been thrown from Brighton Pier by the leader of The Canvey Island Mod Squad, narrowly escapes drowning thanks to the Perfect Master, Cosmic Dick and self-styled Logos of the Aeon (not to mention the reinventer of the Ocarina), Hugo Rune Himself.

Our hero has lost his memory, and, in desperation, agrees to join The Lad Himself in the solving of twelve cases based upon The Brightonomicon, the new zodiac signs formed by the alignment of Brighton streets and discovered by Rune: carriageway constellations.

And together they must find the Chronovision before it falls into the wrong hands and affords ultimate power to the would-be world dictator. And this being an adventure most exciting, they must find it before the sinister Count Otto Black, would-be World Dictator and all-round bad guy. Or the whole world will all go to pot.
