Having been thrown from Brighton Pier by the leader of The Canvey Island Mod Squad, the hero narrowly escapes drowning thanks to the Perfect Master, the self-styled Logos of the Aeon--not to mention the reinventer of the Ocarina--also known as Hugo Rune. The hero has lost his memory, and in desperation he agrees to join The Lad Himself in the solving of 12 mysteries based upon The Brightonomicon, the new zodiac signs formed by the alignment of Brighton streets. Together they must find the Chronovision before it falls into the wrong hands and affords ultimate power to the would-be world dictator Count Otto Black.
