Do Androids Dream of Electric Sheep?

San Francisco lies under a cloud of radioactive dust. People live in half-deserted apartment buildings, and keep electric animals as pets because so many real animals have died. Most people emigrate to Mars - unless they have a job to do on Earth. Like Rick Deckard - android killer for the police and owner of an electric sheep. This week he has to find, identify, and kill six androids which have escaped from Mars. They´re machines, but they look and sound and think like humans - clever, dangerous humans. They will be hard to kill. The film Blade Runner was based on this famous novel.
