The Metamorphosis (German: Die Verwandlung) is a novella by Franz Kafka, first published in 1915. The story begins with a traveling salesman, Gregor Samsa, waking to find himself transformed into a "monstrous vermin".
A terrifying psychological trip into the life of one Joseph K., an ordinary man who wakes up one day to find himself accused of a crime he did not commit, a crime whose nature is never revealed to him. Once arrested, he is released, but must report to court on a regular basis - an event that proves maddening, as nothing is ever resolved. As he grows more uncertain of his fate, his personal life - including work at a bank and his relations with his landlady and a young woman who lives next door - becomes increasingly unpredictable. As K. tries to gain control, he succeeds only in accelerating his own excruciating downward spiral.
