Anyone who loves alternative versions of London a la Neil Gaiman or Alan Moore should get their hands on Albertopolis Disparu, a short story available for free at the Science Museum. It's a densely-laden tale of secret machines, converted turrets and tunnels and Edwardian techno-espionage, played out over the rooftops and catacombs of Exhibition Road. Any eight-page story that references Michael Moorcock and ends with a fleet of Zeppelins attacking Imperial College with plasma weapons is a winner with us. You can pick up a copy from the listening post room at the Museum, or download a PDF (we hear rumours that the green cab shelter opposite the V&A also has free copies). The campaign starts here to persuade the author, Tony White, to turn this into a full-length novel.
