Franz Kafka's most famous novella, Metamorphosis is a masterful mix of horror and absurdity which tells the story of travelling salesman Gregor Samsa, who wakes up one day to find out he has turned into a giant insect. Kafka's novella has been adapted for film and television a number of times, most recently for radio when BBC's Radio 4 broadcast the story, read by Benedict Cumberbatch, to celebrate the 100th anniversary of its first publication.
